photography is a very time-consuming process. If I want to have a color image,
I have to shoot each target least three times through a different filter to
have all three-color channels needed for color image. Also, the exposure times
can be very long, in my case even hundreds of hours for some very dim
objects. An average exposure time is around 25 hours per image. Also everything has
to be carefully pre planned.<o:p></o:p></span></span></p>

methods to be able to control this massive project. I needed to get them ready
first since ones started, the project can't be changed anymore without
canceling it. Everything needs to be spot on, the planning of composition and
its relation to the Milky Way objects, many technical aspects, like how to
handle a data from different optics with a different spatial resolution etc. I
won't go very deep into technical details, since the complex technique needed
is just a tool to make my art. <i><o:p></o:p></i></span></span></p></div><div style="font-style: italic; text-align: center;"><span style="font-family: times; font-size: medium;"><br /></span></div><div style="font-style: italic; text-align: center;"><span style="font-family: times; font-size: medium;"><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-VYFtiDi5n2k/YXPywTknXBI/AAAAAAAAT24/CuZZ42trSh863kTHidpchnljl6oRziYgQCLcBGAsYHQ/s1024/20210702_193300%2Bcopy.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="754" data-original-width="1024" height="472" src="https://1.bp.blogspot.com/-VYFtiDi5n2k/YXPywTknXBI/AAAAAAAAT24/CuZZ42trSh863kTHidpchnljl6oRziYgQCLcBGAsYHQ/w640-h472/20210702_193300%2Bcopy.jpg" width="640" /></a></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><i><span lang="EN-US" style="line-height: 107%;"><br /></span></i></div><div class="separator" style="clear: both; text-align: center;"><i><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-Art4hSR5zLQ/YXPy5s-QXVI/AAAAAAAAT28/Zhj13juRMxUkFobi-BSkIVFn_qh2QEvewCLcBGAsYHQ/s1024/20210702_193154%2Bcopy.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="734" data-original-width="1024" height="458" src="https://1.bp.blogspot.com/-Art4hSR5zLQ/YXPy5s-QXVI/AAAAAAAAT28/Zhj13juRMxUkFobi-BSkIVFn_qh2QEvewCLcBGAsYHQ/w640-h458/20210702_193154%2Bcopy.jpg" width="640" /></a></div></i><i><span lang="EN-US" style="line-height: 19.9733px;">A notebook pages from 2009</span></i></div></span></div><div><p class="MsoNormal" style="line-height: normal; margin-bottom: 13.5pt;"></p><span style="font-family: times;"><span style="font-size: medium;">I like to compare my long imaging projects to a relationship. This project was like that too but not just between two entities. This is like a relationship with the whole family, a large Klan. There might be a nasty drunk uncle or other difficult persons in a family but</span><br /><span style="font-size: medium;">you must be able to get along with them too. I felt like that, when I was stitching pieces</span><br /><span style="font-size: medium;">together and some of them didn't fit the way I wanted and I had to reshoot them. That easily took months, or years. but at the end, everything slides together smoothly without any visible seams.</span><br /><br /><span style="font-size: medium;">I'm a perfectionist, when dealing with my photography. This feature is essential for the great results but it also can cause problems. This photo could be ready maybe five years earlier, if I could leave some extremely dim targets out or leave them less detailed but I simply couldn't do that. When the photo was ready, I didn't remember all of those sleepless cold nights, I remembered the joy I felt when the most difficult parts got ready.</span><br /><span lang="EN-US"><div style="font-size: large;"><br /></div><div><br /><span style="font-size: large;"><br /></span><div style="text-align: center;"><b><span style="font-size: x-large;">Step 2, </span></b></div><div style="text-align: center;"><b><span style="font-size: x-large;"><br /></span></b></div><div style="text-align: center;"><b><span style="font-size: x-large;">COLLECTING THE MATERIAL </span></b></div><div style="text-align: center;"><b><span style="font-size: x-large;"><br /></span></b></div><div style="text-align: center;"><b><span><span style="font-size: x-large;">2009 - 2021</span><br /><br /><br /></span></b></div><div style="text-align: center;"><div style="font-family: "Times New Roman";"><b><span style="color: #999999; font-size: large;">NOTE</span></b></div><div style="font-family: "Times New Roman";"><b><span style="color: #999999; font-size: large;"><br /></span></b></div><div style="font-family: "Times New Roman";"><i><span style="color: #999999; font-size: large;"><b>Each photo in the posters is a slow and complex battle of its own</b></span></i></div></div><div style="font-size: large; text-align: center;"><b><br /></b></div></div>

Many
of us know, how frustrating it can be to notice, that one piece is missing. That's
happened to me too. I was sure that I shot the piece about three years ago

The reason for a long time period is naturally the size of the mosaic and the fact, that image is very deep. Another reason is that I have soht most of the mosaic frames as an individual compositions and publish them as independent artworks. That leads to a kind of complex image set witch is partly overlapping with a lots of unimaged areas between and around frames. I have shot the missing data now and then during the years and last year I was able to publish many sub mosaic images as I got them ready first.<br /><br />My processing workflow is very constant so very little tweaking was needed between the mosaic frames. Total exposure time is over 1250 hours. Some of the frames has more exposure time, than others. There are some extremely dim objects clearly visible in this composition, like a extremely dim supernova remnant W63, the Cygnus Shell. It lays about six degrees up from North America nebula and it can be seen as a pale blue ring. I spent about 100 hours for this SNR alone. An other large and faint supernova remnant in Cygnus can be seen at near right edge of the image. G65.5+5.7 is as large as more famous Veil nebula. There are over 60 exposure hours for this SNR alone. (Veil SNR is just outside of the mosaic area for compositional reasons but can be seen in "Detail" image above.) </div></div><div><br /></div><div><br /></div><div><div style="text-align: center;"><b><span style="font-size: large;">The Mosaic Work, technical info</span></b></div><div><span style="text-align: center;"><br /></span></div><span>I have used several optical configurations for this mosaic image during the years.</span><span style="font-size: medium;"> </span><span>Up to 2014 I was using </span><a href="https://astroanarchy.blogspot.com/2012/09/my-equipment.html">an old Meade LX200 GPS 12" scope,</a><span> QHY9 astrocam, </span><a href="https://astroanarchy.blogspot.com/2009/01/canon-200mm-f18-lens.html">Canon EF 200mm f1.8 camera optics </a><span>and baader narrowband filter set.

After that, I have shot some very high resolution material from the same area of sky and I decided to upgrade my old image with better data. I'm kind of happy with the result, especially the details in dark nebulae are much sharper now and shows the complex structures of unionized gas and dust. Main reason is the long exposure time used, for H-alpha alone, there are 30 hours of exposures. Total exposure time is around 60 hours.</p><p>The dark nebula in the upper part of the photo is the gas bridge splitting visually the Pelican Nebula and the North America nebula so that the they look like two separate nebula. In reality they are actually a one large emission area.<br /><br /></p><div style="text-align: center;"><b><span style="font-size: large;">Pelican Nebula, constellation Cygnus, the Swan</span></b></div><div style="text-align: center;"><span>Click for a large image</span></div><div style="text-align: center;"><span><br /></span></div><div style="text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjJLTx6aTQGSyYo2HIF9DRCaBYeNd8g8Q1lW1SAcg_EOA0DKl-5KPI4Fxs2280zZ0Iv5qVjbqg9aRjIvNv7xyfxW9vay7Ym_DuF8uR9g4nKAfhkrXAhThmnaw3d4HS-11kRadQ3fneL_9X2uw0jDQWh46bA58Lrxwyb7dm5vnfq3B0EPFhgz4VtniW7aw=s1178" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1178" data-original-width="900" height="838" src="https://blogger.googleusercontent.com/img/a/AVvXsEjJLTx6aTQGSyYo2HIF9DRCaBYeNd8g8Q1lW1SAcg_EOA0DKl-5KPI4Fxs2280zZ0Iv5qVjbqg9aRjIvNv7xyfxW9vay7Ym_DuF8uR9g4nKAfhkrXAhThmnaw3d4HS-11kRadQ3fneL_9X2uw0jDQWh46bA58Lrxwyb7dm5vnfq3B0EPFhgz4VtniW7aw=w640-h838" width="640" /></a></div><i>Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. </i></div><div style="text-align: center;"><i>The older version of this image can be seen here: <a href="https://astroanarchy.blogspot.com/2016/12/pelican-nebula-two-frame-mosaic.html">https://astroanarchy.blogspot.com/2016/12/pelican-nebula-two-frame-mosaic.html</a><br /></i><br /><br /><b><span style="font-size: large;">Zoomable Image<br /><br /></span></b></div><div style="text-align: center;"><iframe allowfullscreen="true" height="900" src="https://www.easyzoom.com/embed/307214?roi=%5B1452%2C-2971%2C4%5D" width="640"></iframe></div><div style="text-align: center;"><br /></div><div style="text-align: center;"><br /></div><div style="text-align: center;"><br /></div><div style="text-align: center;"><b><span style="font-size: large;">Orientation in large context</span></b></div><div style="text-align: center;"><b><span style="font-size: large;"><br /></span></b></div><div style="text-align: center;"><div class="separator" style="clear: both; font-weight: bold; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhVPo1-NOffW1JQG75cGve2MjyxRa8U-pZBEaf5-81RLNADR2seRCcl2KNo5y14d_JMu5_Ex91DtLj0a7Htpgk3JvSk4peUIvUB5wRBbnH6kwem9Oej4NjJ-9HENV2ieUfn4dZEHGNtQYSGKGannKcpjohGJ5qZILomfitEq5YX2xfEyuNoWvnB70RKtg=s1491" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1150" data-original-width="1491" height="494" src="https://blogger.googleusercontent.com/img/a/AVvXsEhVPo1-NOffW1JQG75cGve2MjyxRa8U-pZBEaf5-81RLNADR2seRCcl2KNo5y14d_JMu5_Ex91DtLj0a7Htpgk3JvSk4peUIvUB5wRBbnH6kwem9Oej4NjJ-9HENV2ieUfn4dZEHGNtQYSGKGannKcpjohGJ5qZILomfitEq5YX2xfEyuNoWvnB70RKtg=w640-h494" width="640" /></a></div><i>The North America Nebula can be seen at upper part of the image</i><span style="font-size: large; font-weight: bold;"><br /></span></div><div style="text-align: center;"><i><br /></i></div><div style="text-align: center;"><br /></div><div style="text-align: center;"><br /></div><div style="text-align: center;"><br /></div>J-P Metsavainiohttp://www.blogger.com/profile/17779793358827771439noreply@blogger.com0tag:blogger.com,1999:blog-6953966401086641771.post-15625348107554010492021-11-24T16:56:00.008+02:002021-11-24T16:56:52.540+02:00The Great Wall of Cygnus<p><span style="font-size: medium;"> Due to very cloudy weather I have remade some of my older photos, this time the Cygnus Wall has been remade. This is a combination of several older images from 2008, 2010 and 2014. Two different longer focal length telescope was used, The Meade LX200 GPS 12" and Celestron Edge 11". Beside long focal length images material from shorter focal length optics was used from the Canon EF 200mm f1,8 and Tokina AT-x 300mm f2.8 camera optics. Older material was taken with the QHY9 astro camera and after 2014 Apogee Alta U16 camera was used. Total exposure time is around 30 hours.<br /></span></p><div style="text-align: center;"><span style="font-size: x-large; font-weight: bold;">The Great Wall of Cygnus<br /></span>Click for a large image <br /><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-_wz7BkutxH4/YZ5PVNyWTYI/AAAAAAAAT-Y/Y3MuCTZObcYrDNSTRdG_26nhRlOl_wV0wCLcBGAsYHQ/s1481/GreatWall2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1481" data-original-width="1228" height="772" src="https://1.bp.blogspot.com/-_wz7BkutxH4/YZ5PVNyWTYI/AAAAAAAAT-Y/Y3MuCTZObcYrDNSTRdG_26nhRlOl_wV0wCLcBGAsYHQ/w640-h772/GreatWall2.jpg" width="640" /></a><br /><i>Mapped colors from an emission of the ionized elements, Red=Sulfur, Green=Hydrogen and the Blue =Oxygen.</i></div><br /><div style="text-align: center;"><b><br /><span style="font-size: x-large;"> Wider field<br /></span></b>Click for a large image </div><div style="text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-oqHNVY1i3uY/YZ5P2tEwSdI/AAAAAAAAT-g/1hzzJIcMvlg9mqHetbKGJT2pBwW2aVw7gCLcBGAsYHQ/s1740/GreatWall.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1530" data-original-width="1740" height="562" src="https://1.bp.blogspot.com/-oqHNVY1i3uY/YZ5P2tEwSdI/AAAAAAAAT-g/1hzzJIcMvlg9mqHetbKGJT2pBwW2aVw7gCLcBGAsYHQ/w640-h562/GreatWall.jpg" width="640" /></a></div><br /><div style="text-align: center;"><br /></div><div style="text-align: center;"><br /></div><div style="text-align: center;"><span style="font-size: x-large;"><b>Zoomable Photo</b></span></div><p></p><iframe allowfullscreen="false" height="900" src="https://www.easyzoom.com/embed/303383?roi=%5B1513%2C-1614%2C3%5D" width="640"></iframe><div><br /></div><div><span style="font-size: large;"><br /></span></div><div><span style="font-size: large;"><br /></span></div><div style="text-align: center;"><b><span style="font-size: large;">Info about imaging technique</span></b></div><div><span style="font-size: large;"><br /></span></div><div><span style="font-size: large;">I have used my new processing/imaging technique VARES for this new composition (VAriable Resolution Imaging) It's really powerful toolset when data from very different focal lengths are combined to a single high resolution image.

Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to know its absolute location since we know its relative location. Stars ionizing the nebula have to be very close to the nebula structure itself. I usually divide up the rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available, I use them, but most of the time my rule of thumb is sufficient. By using a scientific estimate of the distance of the Milky Way object, I can locate the correct number of stars in front of it and behind it.</div></span><div style="text-align: left;"><br /></div><span style="text-align: left;"><div style="text-align: left;">Emission nebulae are not lit up directly by starlight; they are usually way too large for that. Rather, stellar radiation ionizes elements within the gas cloud and the nebula itself is glowing light, the principle is very much the same as in fluorescent tubes. The thickness of the nebula can be estimated from its brightness, since the whole volume of gas is glowing, brighter means thicker.</div></span><div style="text-align: left;"><br /></div><span style="text-align: left;"><div style="text-align: left;">By this means, forms of the nebula can be turned to a real 3-D shape. Nebulae are also more or less transparent, so we can see both sides of it at the same time, and this makes model-making a little easier since not much is hidden.</div></span><div style="text-align: left;"><br /></div><span style="text-align: left;"><div style="text-align: left;">The local stellar wind, from the star cluster inside the nebula, shapes the nebula by blowing away the gas around the star cluster. The stellar wind usually forms a kind of cavity in the nebulosity. The same stellar wind also initiates the further collapse of the gas cloud and the birth of the second generation of stars in the nebula. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.</div></span><div style="text-align: left;"><br /></div><span style="text-align: left;"><div style="text-align: left;">Ionized oxygen (O-III) glows with a bluish light, and since oxygen needs a lot of energy to ionize it, this can only be achieved relatively close to the star cluster in the nebula. I use this information to position the O-III area (the bluish glow) at the correct distance relative to the heart of the nebula.</div></span><div style="text-align: left;"><br /></div><span style="text-align: left;"><div style="text-align: left;">Many other small indicators can be found by carefully studying the image itself. For example, if there is a dark nebula in the image, it must be located in front of the emission one, otherwise we couldn’t see it at all.</div></span><div style="text-align: left;"><br /></div><span style="text-align: left;"><div style="text-align: left;">Using the known data in this way I build a kind of skeleton model of the nebula.

Pickering's Triangle is part of the Veil nebula supernova remnant in constellation Cygnus. It has an amazing structure of complex gas filaments. This image is one of the most detailed presentations, showing the whole triangle shape formation, I have seen so far.<br /><br />Image is in visual palette from emission of an ionized elements, hydrogen (H-alpha), sulfur (S-II) and oxygen (O-III). Red=Hydrogen + 33% sulfur, Green=oxygen and Blue=oxygen + 33% hydrogen to compensate otherwise missing H-beta emission. (H-beta and H-alpha has a same shape but H-beta is weaker. H-alpha emits red light and H-beta emits blue light.)

The scientific information makes my inner visions much more accurate, and the 3-D technique I have developed enables me to share those beautiful visions with others.<br /><br />How accurate my 3-D-visions are depending on how much information I have and how well I implement it.<br /><br />The final 3-D-image is always an appraised simulation of reality based on known scientific facts, deduction, and some artistic creativity.<br /><br />After I have collected all the necessary scientific information about my target, I start my 3-D conversion from stars. Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to know its absolute location since we know its relative location. Stars ionizing the nebula have to be very close to the nebula structure itself. I usually divide up the rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available, I use them, but most of the time my rule of thumb is sufficient. By using a scientific estimate of the distance of the Milky Way object, I can locate the correct number of stars in front of it and behind it.<br /><br />Emission nebulae are not lit up directly by starlight; they are usually way too large for that. Rather, stellar radiation ionizes elements within the gas cloud and the nebula itself is glowing light, the principle is very much the same as in fluorescent tubes. The thickness of the nebula can be estimated from its brightness, since the whole volume of gas is glowing, brighter means thicker. <br /><br />By this means, forms of the nebula can be turned to a real 3-D shape. Nebulae are also more or less transparent, so we can see both sides of it at the same time, and this makes model-making a little easier since not much is hidden.<br /><br />The local stellar wind, from the star cluster inside the nebula, shapes the nebula by blowing away the gas around the star cluster. The stellar wind usually forms a kind of cavity in the nebulosity. The same stellar wind also initiates the further collapse of the gas cloud and the birth of the second generation of stars in the nebula. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.<br /><br />Ionized oxygen (O-III) glows with a bluish light, and since oxygen needs a lot of energy to ionize it, this can only be achieved relatively close to the star cluster in the nebula. I use this information to position the O-III area (the bluish glow) at the correct distance relative to the heart of the nebula.<br /><br />Many other small indicators can be found by carefully studying the image itself. For example, if there is a dark nebula in the image, it must be located in front of the emission one, otherwise we couldn’t see it at all.<br /><br />Using the known data in this way I build a kind of skeleton model of the nebula. Then the artistic part is mixed with the scientific and logical elements, and after that the rest is very much like creating a sculpture on a cosmic scale</span><div><span style="font-size: medium;"><br /></span></div><div><div style="text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-679nRF0j2ps/YUOI2ifWOuI/AAAAAAAATv8/F1OwTU-780k1ZWU3QsGb7n1FVrP2k8ifgCLcBGAsYHQ/s928/TS1.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="792" data-original-width="928" height="546" src="https://1.bp.blogspot.com/-679nRF0j2ps/YUOI2ifWOuI/AAAAAAAATv8/F1OwTU-780k1ZWU3QsGb7n1FVrP2k8ifgCLcBGAsYHQ/w640-h546/TS1.jpg" width="640" /></a></div><i>3D-model without textures</i><br /><span style="font-size: large;"><br /></span></div><br /></div>J-P Metsavainiohttp://www.blogger.com/profile/17779793358827771439noreply@blogger.com0tag:blogger.com,1999:blog-6953966401086641771.post-39289821301556823412021-09-13T11:06:00.009+03:002021-09-14T15:50:18.601+03:00Beyond the astronomical photography<p style="text-align: center;"><i style="font-size: x-large;">NOTE.

The Vision series of photos are forming visual notes about shapes, structures, textures, and colors I have seen and captured during my couple of decades-long journey as an astronomical nature photographer.</span></p><p><span style="font-size: large;">Every single element in Vision series photos are from my original astronomical photos. I have been using the Overlapping Lightning Method (Multi Exposure Method) to create my Vision series photographs. By this method the forms and structures in astronomical object get multiplied, they are now forming a new visual dimension beyond our physical universe.</span></p><p><span style="font-size: large;">The photographic method I'm using was fashionable back in the 1920s among avant-gardists and surrealistic photographers. At the time the work was done in a darkroom, I’m using about the same technique but instead of a darkroom, I’m using digital image processing.</span></p><p><span style="font-size: large;">The original photo is rotated, moved, and/or mirrored as I like, and then multiple layers stacked back together so that the original brightness is maintained. For this task, I use Photoshop and various astronomical stacking methods and applications.<br /></span></p><p><span style="font-size: large;">Few samples of my Vision Series, the original astronomical photo I used to create them at end of the page.</span></p><p></p><p style="text-align: center;"><span style="font-size: x-large;"><b>Visions of Veil<br /></b></span>Please, click for a large image </p><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-uIV5eqKHiJk/YT8M5lTZpVI/AAAAAAAATvI/QjbKJjQoGM8vsET-QmBPMszLeCmVbfPZwCLcBGAsYHQ/s1557/HSTOssssWddLxx3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1557" data-original-width="1542" height="640" src="https://1.bp.blogspot.com/-uIV5eqKHiJk/YT8M5lTZpVI/AAAAAAAATvI/QjbKJjQoGM8vsET-QmBPMszLeCmVbfPZwCLcBGAsYHQ/w634-h640/HSTOssssWddLxx3.jpg" width="634" /></a></div><br /></div><div><br /></div><div><br /></div><p style="text-align: center;"><a href="https://1.bp.blogspot.com/-mxPcmO96lhs/YT8DfE5TrvI/AAAAAAAATuc/02QKHHKMLLgY2RdT1LFTbyYow7a5Ex99wCLcBGAsYHQ/s1557/HSTOssWL3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1557" data-original-width="1542" height="640" src="https://1.bp.blogspot.com/-mxPcmO96lhs/YT8DfE5TrvI/AAAAAAAATuc/02QKHHKMLLgY2RdT1LFTbyYow7a5Ex99wCLcBGAsYHQ/w634-h640/HSTOssWL3.jpg" width="634" /></a></p><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-bxAEZzSDqCs/YT8DmGSSsWI/AAAAAAAATuk/GTIpH8I_DY0F-kE6TNBmx4ZrFvL5dbGewCLcBGAsYHQ/s1557/HSTOssssWddL3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1557" data-original-width="1542" height="640" src="https://1.bp.blogspot.com/-bxAEZzSDqCs/YT8DmGSSsWI/AAAAAAAATuk/GTIpH8I_DY0F-kE6TNBmx4ZrFvL5dbGewCLcBGAsYHQ/w634-h640/HSTOssssWddL3.jpg" width="634" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-sImLKKFxscU/YT8Dr7uywTI/AAAAAAAATuo/Gwh01ynD0uAR76E8VtYdNq7VLt0EMoGewCLcBGAsYHQ/s1557/HSTOssssWrrddL3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1557" data-original-width="1542" height="640" src="https://1.bp.blogspot.com/-sImLKKFxscU/YT8Dr7uywTI/AAAAAAAATuo/Gwh01ynD0uAR76E8VtYdNq7VLt0EMoGewCLcBGAsYHQ/w634-h640/HSTOssssWrrddL3.jpg" width="634" /></a></div><div><br /></div><br /><div class="separator" style="clear: both; text-align: center;"><p><b><span style="font-size: large;"><i>Visions of Veil </i>series is based on my original photo</span></b></p><p></p><div class="separator" style="clear: both; font-weight: bold;"><a href="https://1.bp.blogspot.com/-V_WqXfOVIB0/YT8EIpp9hII/AAAAAAAATu4/f6Nu215J34EewD8UzntPQ2RRltC3Nk5qwCLcBGAsYHQ/s1350/IC443%2Bcopy.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1350" data-original-width="1330" height="640" src="https://1.bp.blogspot.com/-V_WqXfOVIB0/YT8EIpp9hII/AAAAAAAATu4/f6Nu215J34EewD8UzntPQ2RRltC3Nk5qwCLcBGAsYHQ/w630-h640/IC443%2Bcopy.jpg" width="630" /></a></div><div class="separator" style="clear: both;"><b>Image info can be seen here, </b><a href="https://astroanarchy.blogspot.com/2015/09/pickerings-triangle-my-first-light-for.html"><span style="font-size: xx-small;">https://astroanarchy.blogspot.com/2015/09/pickerings-triangle-my-first-light-for.html</span></a></div><div class="separator" style="clear: both;"><br /></div><div class="separator" style="clear: both;"><br /></div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both;"><br /></div><p></p></div><br />J-P Metsavainiohttp://www.blogger.com/profile/17779793358827771439noreply@blogger.com0tag:blogger.com,1999:blog-6953966401086641771.post-4545943468686889072021-08-27T13:20:00.115+03:002021-08-28T11:50:24.724+03:00Visions of Veil<p> <span style="text-align: center;">This is an experimental test with a </span><a href="http://astroanarchy.zenfolio.com/p396910303" style="text-align: center;"><span style="color: #cc0000;">3D-conversion of my astronomical image</span></a><span style="text-align: center;">.

I did develop a unique process to create scientifically accurate 3D volumetric images of 'my' nebulas. The final 3D volumetric image is always an appraised simulation of reality based on known scientific data, deduction, and some artistic creativity.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">After I have collected all the necessary scientific information about my target, I start my 3-D conversion using the stars in the image. Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to know its absolute location since we know its relative location. Stars ionizing the nebula have to be very close to the nebula structure itself. I usually divide up the rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available, I use them, but most of the time my rule of thumb is sufficient. By using a scientific estimate of the distance of the Milky Way object, I can then locate the correct number of stars in front of it and behind it.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">Emission nebulae are not lit up directly by starlight; they are usually way too large for that. Rather, stellar radiation ionizes elements within the gas cloud. So, it’s the nebula itself that is glowing. (The principle is very much the same as in fluorescent tubes.) The thickness of the nebula can be estimated from its brightness, since the whole volume of gas is glowing, brighter means thicker. Nebulae are also more or less transparent, so we can see both sides of it at the same time, and this makes model-making a little easier since not much is hidden.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">The local stellar wind, from the star cluster inside the nebula, shapes the nebula by blowing away the gas around the star cluster. The stellar wind usually forms a kind of cavity in the nebulosity. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">Oxygen needs a lot energy to ionize it, this can only be achieved relatively close to the star cluster in the nebula. I use this information to position the O-III area (the bluish glow) at the correct distance relative to the heart of the nebula.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">Many other small indicators can be found by carefully studying the image itself. For example, if there is a dark nebula in the image, it must be located in front of the emission nebula, otherwise we can’t see it.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">Explosions in space are more or less symmetrical, due to that, most of the supernova remnants and planetary nebulae mainly has a ball like appearance.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">Using the known data in this way I build a kind of skeleton model of the nebula. Then the artistic part is mixed with the scientific and logical elements, and after that the rest is very much like creating a sculpture on a cosmic scale.</div></span></div><div style="text-align: left;"><span style="text-align: center;"><br /></span></div><div style="text-align: left;"><span style="text-align: center;"><br /></span></div><div style="text-align: left;"><span style="text-align: center;"><br /></span></div><div style="text-align: left;"><span style="text-align: center;"><br /></span></div></div></div>
