NEW SETUP FOR MY ASTRONOMICAL NATURE IMAGING WORK

 I haven't publish much new images in past two three years since I have had some health problems. Now I'm good as new and can start working again. Past two years I have been slowly building a new imaging platform. I have done some shorter focal length work past six years, now it's time to go closer again.


OPTICS

System is build around Celestron EDGE 14" telescope, I selected this scope due to its light gathering capacity, 356mm diameter and 3910mm native focal length (This very large and heavy 0.7 Reducer is especially made for the EDGE 14") One main difference to normal Celestron EDGE telescope is that I have added a secondary mirror focuser (by Optec)  to get rid of a mirror flop. It can be a problem, especially with a heavy mirror. Bottom line,  this scope has an excellent optical quality. There is some optical analysis and a single full scale 20min frame at end of this post.

In future I can add a "HyperStar system" to replace secondary mirror and use this telescope as a fast f2 astrograph. 


Secondary mirror focuser, Note a curved vane for the flat power/data cable, no diffraction spikes!



MOUNT

I ended up to a MESU Mount MARK II since it has 100kg capacity at imaging work with a periodic error less than 4 arcseconds peak-to-peak, impressive numbers indeed. It also has zero lash back due to its friction drive system.
The pillar I ordered with the mount is bended knee pillar type, that mean, no meridian flip is needed and telescope can track whole sky without stopping. The pillar came in easy to handle parts and assembly was very straight forward, the assembled pillar is very rigid under the weight of heavy telescope, counter weights and accessories. Mesu mount is absolute beautiful engineering work. Support from manufacture is also very good. I had some minor problems with settings at first but they get solved in no time after we went it trough with remote connection, while on site. Bottom line, money wise this mount is a real bargain, if compared its features to any other brand or model of mount.

Bended Knee Pillar angle at my location 65 degree North. 
Counter weights are stainless steal weight lifting weights. (~35kg)

The 14" Telescope barely fits to my SkyShed POD



CAMERA AND ACCESSORIES


CAMERA

The Main camera is a "new" Apogee Alta U9000M with Apogee Filter wheel. It's a second hand camera originally used for the microscopic work and it looks like a bran new, There wasn't any mechanical shutter but I moved a shutter from my old Apogee Alta U16 to this new camera. (My old camera died to old age)
It has 12 micron pixels and it's perfect match to this optical configuration giving imaging scale of 0.9 arcseconds per pixel. The full image spans 46.1 x 46.1 arcminutes of sky. (One degree is 60 arcminutes and Full Moon spans around 30 arcminutes of sky)

INSTRUMENT ROTATOR

At first time I have added an instrument rotator to the imaging path. I haven't use any rotator earlier since there is always some flexure. The Wanderer Astro Rotator Pro has absolute zero flexure by the manufacture. I was skeptical to this since if it moves, it will flex. It turned out, that there is a patented system based on neodymium magnets around the light path holding everything tightly together even when rotator moves.  After measuring carefully everything with the CCD-inspector software from test exposures under the starfield I can say, it really has no flexures at all. It's only 18 mm thick and fit to my limited back focus nicely. It can handle flawlessly all the heavy load I have placed behind the rotator.

ACTIVE OPTIC UNIT

Maybe an overkill but I have added an active optics unit to the light path. It's SXV-AO from Starlight Xpress UK.
I have had really good experiences with long focal length imaging with AO unit during the years. It doesn't correct the actual seeing so much but it corrects every small or big error from heat bubbles and vibrations from heavy traffic, wind, etc. and it does that really really fast. It's as easy to use as any OAG, especially since I have a rotator now. With 14" scope I can guide around 10 HZ by using mag 11 guide star. The MESU Mount is really good but there is lots of mass to move when guiding corrections are made. With AO there is just a small refracting glass element to move instead of telescope and heavy accessories.

DATA & POWER BOX

An other new accessory is power and data box from Wanderer Astro. It makes the system less chaotic with all the data and power cords. Also controlling power and data connections can be done remotely in one software. It can handle nearly 20 amp at peak power.

DEW BUSTER

There is also my old Dew Buster installed to the telescope. it can keep the temperature just little over the dew point, this prevent the heat current. Raising warm air inside the tube will ruin the image, if heater is even slightly too warm.

FAN

I added a 70 mm computer fan to the telescopes air went to reduce the cool down time. There is an air filter in the went to prevent the dust getting inside the OTA. I can control the fan speed by the Power Box software.

QHY POLEMASTER

This is a new addition too, I was amazed how easy it was to use. Polar align took maybe 15 min and it's easy to redo at any time needed. here is a REVIEW about this little helper,



Telescope elements labeled


QHY Polemaster, lens cover removed and ready for the action.


LENS COVER

As a last item here is a lens cover for Celestron EDGE 14" telescope. It's a simple and a must accessory to prevent dust in the collector lens. How ever, in my case there is a secondary mirror focuser sticking out and it prevents to use the standard Celestron aluminium cover over the telescope. 
I solved a problem by cutting a circular hole in the lens cover. After that I bought a steel bowl from local market ( it was just 5 € or about 5 $)  I sprayed it matt black and glued it to the cover with an elastic, rubber like, superglue.

OPTICAL ANALYSIS FROM THE CCDINSPECTOR APP


The optical collimation is as good as I get it in my seeing conditions and the optical tube hold it perfectly since the main mirror is always locked down and focusing is done with the Optec Secondary Mirror Focuser only.




This is a 3D-plot of field curvature from the CCDInspector app of Celestron Edge 14" with 0.7 Focal Reducer and Apogee Alta U9000M with 12 micron pixels. This configuration produce a very flat field and stars are sharp from edge to edge in the whole field. This is impressive especially since the CCD in Alta U9000M is so large, about 37x37mm. 

A single full scale 20 min O-III exposure used for the optical analysis

This is one of the test shots after the collimation procedure. Exposure time is 1200s with 3nm O-III filter. Image is calibrated with Dark Frame and Bias corrected Flat Frame. Target is WR 134 in Cygnus. Stars are pinpoint from corner to corner. There is no stretching done, Click for a full scale image.

Grand Mosaic of the Milky Way is now large than ever


Last Spring I published a large mosaic photo of the Milky Way and it went viral!
I have now even a large version of it, the mosaic spans 145 degrees of sky from Orion to Cygnus, the previous version showed 120 degrees of sky.

The new panorama image was published today in Finnish Tähdet ja Avaruus Magazine 
at first time in the World.

This and other of my astronomical photographs can be seen in my NIGHT FEVER exhibition in Helsinki.

WHY?

The reason I keep doing my slow work is an endless curiosity, I love to show how wonderful our world really is. That's how I feel at front of everything I'm able to see through my photography. This is my purpose as an artist. I have to fulfil the demands of my passion – and I have done so for about 25 years.

Photographed area of sky is showing a large part of Northern Milky Way in high resolution. Beside the size, it's very deep, meaning that it shows extremely dim and unimaged nebulae across the galaxy plane. One of the reasons for this massive panorama project was a fact, that there was no such an image anywhere in the world.  I had personal need for the photo like this since I wanted to use it as a map to the new adventures.

Revealing the hidden beauty of our universe is my passion. I stand in rapt adoration before all that I see. When art meets science, the results can be quite mind-blowing.


HOW?



Step 1, 

PLANNING

Astronomical 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.

I made imaging plans over ten years ago, I wrote first ideas about this imaging project to my little black Moleskin notebook. I was aware at the time, that it will take a decade to be finalized but it doesn't bother me since I love long projects, they are giving a purpose and the goal to my work as an artist. 


My little black notebook and first plans for the project at 2008

A notebook page opening from Autumn 2008

I needed to develop many new working 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.  




A notebook pages from 2009

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
you must be able to get along with them too. I felt like that, when I was stitching pieces
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.

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.



Step 2, 

COLLECTING THE MATERIAL 

2009 - 2021


NOTE

Each photo in the posters is a slow and complex battle of its own

Some of my individual photos shot between 2009 and 2021 are collected here. Most of them are now part of the Large Mosaic Image of the Milky Way galaxy.

Step 3, 

2019 -2021, SOLVING THE BIG PUZZLE

Finally at 2019, after so many years, I had enough material to start working with the final mosaic image. The work took about two years due to complex mosaic structure and massive amount of image material. I also needed to shoot lots of missing material for the mosaic at the same time

I used the Cartes du Ciel, a star map software, for planning and a preliminary fit the individual frames.

ALL THE PIECES OF A 

 COSMIC PUZZLE CONNECTED

The final photo is over 120 000 pixels wide and it has 301 individual mosaic panel. Most of the objects are originally shot as a self-standing artworks, due to that, they are in various positions and angles to each other. This is the reason, why the final mosaic structure looks so complicated, as can be seen in this image.

AND FINALLY

At October 2021, after 12 years, 1500 hours of exposures and countless hours of work

Getting to a last piece of the puzzle is always a thrilling process. 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 but couldn't find it anywhere from my hard drives. As a result, I had to wait several extremely long weeks to be able to reshoot the missing piece to get this massive puzzle finalized. 


The Mosaic Work, technical info

I have used several optical configurations for this mosaic image during the years. Up to 2014 I was using an old Meade LX200 GPS 12" scope, QHY9 astrocam, Canon E200mmf1.8 camera optics and baader narrowband filter set.


I have shot many details with a longer focal length, before 2014 by using Meade 12" scope with reducer and after 2014 Celestron EDGE 11" and reducer. Quider camera has been Lodestar and Lodestar II.

I took my current toolset as a base tool since it has a relatively high resolution combined to a very large field of view. Also it collects photons very quickly since it's undersampled and I can have very dim background nebulosity visible in very short time (many times 30 min frame is enough)

I do all my mosaic work under the PhotoShop, Matching the separate panels by using stars as an indicator is kind of straight forward work. My processing has become so constant, that very little tweaking was needed between separate frames, just some minor levels, curves and color balance. 

I have used lots of longer focal length sub-frames in my mosaic to boost details. (See the mosaic map at top of the page) To match them with shorter focal length shots I developed a new method.

Firstly I upscale the short focal length frames about 25% to have more room for high resolution images.Then I match the high res photo to a mosaic by using the stars as an indicator. After that I remove all the tiny stars from the high res image. Next I separate stars from low res photo and merge the starless high res data to a starless low res frame. And finally I place the removed low res stars back at top of everything with zero data lost. Usually there are some optical distortions and it's seen especially in a star field. Now all my stars are coming from a same optical setup and I don't have any problems with distortions. (I'm using the same star removal technique as in my Tone Mapping Workflow)

Milky Way, 12 years, 1250 hours of exposures and 125 x 22 degrees of sky

You can buy prints by using the contact form at right


It took nearly twelve years to collect enough data for this high resolution gigapixel class mosaic image of the Milky Way.  Total exposure time used is around 1250 hours between 2009 and 2021.


" I can hear music in this composition, from the high sounds of sparcs and bubbles at left  all the way to a deep and massive sounds at right."


The final photo is about 100 000 pixels wide, it has 234 individual mosaic panels stitched together and 1,7 gigapixels. (Click for a large image) All the frames used are marked in this image. Since many of sub-images and mosaics are independent artworks it leads to a very complex mosaic structure.

Imaging info

Image spans 125 x 22 degrees of  the Milky About 20 million individual stars are visible in my photo!

It took almost twelve years to finalize this mosaic image. 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.

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.) 


The Mosaic Work, technical info

I have used several optical configurations for this mosaic image during the years. Up to 2014 I was using an old Meade LX200 GPS 12" scope, QHY9 astrocam, Canon EF 200mm f1.8 camera optics and baader narrowband filter set. After 2014 I have had 10-micron 1000 equatorial mount, Apogee Alta U16 astro camera, Tokina AT-x 200mm f2.8 camera lens and the Astrodon 50mm square narrowband filter set. I have shot many details with a longer focal length, before 2014 by using Meade 12" scope with reducer and after 2014 Celestron EDGE 11" and reducer. Quider camera has been Lodestar and Lodestar II.

Sharpless 114, a Cosmic Dragon, is now the Ukrainian Ironbelly



This cosmic photograph is dedicated to Ukrainian people and a deadly fight they are forced to. 

The whole world is now witnessing the barbaric actions of the brutal Russian dictator Putin. As an artist and astrophotographer, I thought about what I could do to help Ukraine and its people. All proceeds from the sale of this NFT will go to efforts supporting the Ukrainian people during this war.

I have renamed Sharpless 114, the Flying Dragon Nebula, to the Ukrainian Ironbelly, after a dragon seen in Harry Potter movie, Harry Potter and the Deathly Hallows: Part 2

A story behind this artwork

Few days ago I was working with my new photo, showing a rarely imaged object Sharpless 114 in Eastern part of constellation Cygnus, the Swan. The official nickname for the object is the Flying Dragon Nebula. As I worked with this photo, I had a strong feeling that I have seen it before but I couldn't remember where.

I woke up in the middle of the night realizing that I have seen this nebula in the movie,  Harry Potter and the Deathly Hallows: Part 2  (Yes, I'm a nerd)

There is a magical creature in a movie, a massive dragon called the Ukrainian Ironbelly. It turned out to be the creature that among other things, helped Ukrainians during the WW1 as a "wizarding air force" (Source Harry Potter Fandom Wiki)

I believe that this can be a great symbol for the Ukrainian fight against the Russian monsters.

This is also a great symbol for a modern version of Ukrainian Ironbelly, the Turkish made drone, Bayraktar-TB2, a most important weapon in war against Russians tanks in Ukraine. As a dragon, this drone is producing a steel melting "jet of fire" against murderess Russian main battle tanks and saves countless of Ukrainian lives as we speak.

This is an extremely personal art project to me as a Finnish citizen. We have a 1340 km (830 mi) common border with Russia and there is a huge risk that we might be the next victims of the brutal dictator of Russia.

All proceeds from the sale of this NFT will go to efforts supporting the Ukrainian people during this war.


History of Ukrainian Ironbelly by Harry Potter Fandom
Source: https://harrypotter.fandom.com/wiki/Ukrainian_Ironbelly

Ironbellies had been subject to constant observation by the Ukrainian wizarding authorities, ever since a particular Ironbelly carried off a sailing ship from the Black Sea in 1799. Thankfully, the boat was empty at the time.

In 1926, Newt Scamander mentioned to Jacob Kowalski that he had previously worked with Ukrainian Ironbellies during the First World War. In that same war, Ukrainian Ironbellies were also considered for use in a wizarding air force. The Ironbelly could produce jets of flame up to 3,560 degrees Fahrenheit (1960 degrees Celsius).

INFO about Sharpless 114, Sh2-114

Sh2-114 is a complex and unusual HII emission nebula. Its complex, wispy structure is likely the result of winds from hot, massive stars interacting with the magnetic fields in the interstellar medium. But very little is known about it.
