All my photos from year 2020
The year 2020 has been interesting since I'm between the scopes at the moment. I converted my old Tokina At-x 300 mm f2.8 camera optics and paired it with the Apogee Alta U16 astro camera.
At first it looked like an impossible task since the back focus distance of Tokina lens was way too short for the camera. After some heavy handed modifications (including an angle grinder) I managed to marry those too junks of metal, glass and silicon together. Kind of Frankenstein's monster but worked!
After many years shooting with a long focal length instrument it was like a fresh air to work with wide field tool.

Cygnus mosaic gets large
The new composition is made so that the veil nebula supernova remnant fits to the field of view.
There are three large supernova remnants visible in this image. The Veil nebula is the most bright of them, other two are really dim and diffused. I spent about 200 exposure hours for those two alone to show them well. I call this trio to the Three musketeers.
I like the new composition, it's very dynamic and shows the whole constellation Cygnus first time ever at this detail level and deepness. Least I haven't seen anything like this before. Image spans now 31 x 23 degrees of sky and has 118 individual frames in it. total exposure time is now around 700 hours and the resolution 20.000 x 25.500 pixels. Image it took over a decade to finalize this photo between 2010 and 2021.
The previous version of this mosaic can be seen here, Great Mosaic of Cygnus

Three large supernova remnants in constellation Cygnus, the Swan, are in image as colored circles
NOTE, there is an apparent size of the Moon as a scale at lower right corner in a grayscale image.
Beside three supernova remnants there are two Wolf Rayet stars with outer shell formations. NGC 6888, the Crescent Nebula at center of the image and the WR 134, it can be seen as a blue arch just right from the Crescent Nebula, near the Tulip nebula.
Next to the Tulip Nebula lays a Black hole Cygnus X-1, it's marked in small closeup image of the Tulip Nebula at center right in orientation image above.
Constellation Cygnus is an endless source of celestial wonders, both scientifically and aesthetically. For me, as an visual artist, this are of night sky is very inspiring There are endless amount of amazing shapes and structures, I can spend rest of my life just shooting images from this treasury.

Treasures of Cygnus
Technical data and other information
You will found all the images in this collection from my portfolio with technical details.

Collection of images from the Veil nebula supernova remnant
Note. a large image, ~3MB
I have published this image at Autumn 2012, more info in this blog post:

The Cygnus mosaic
Note. A large image 2200x1400 pixels and ~5MB.
The large mosaic of constellation Cygnus covers 22x14 degrees of sky. Total exposure time with QHY9 astrocam and Baader narrowband filters is ~120h.
A Chinese Dragon Nebula
The large panorama of Cygnus looks very much like a "Chinese Dragon"!

Grande mosaic of Cygnus, 18-panels, over 150 hours and 22 x 14 degrees of sky
I have originally published this image back at December 9, 2011 After that I have shot many details out of this are of sky with much longer focal length instrument. Mainly with Celestron Edge 11" reflecting telescope. I have now updated this photo with a new image material and I thought, that it's a good time to republish this updated image again.
The Great mosaic image of constellation Cygnus has 18 individual panels stitched together seamlessly. Each panel has shot three times for a color image. First I shot the light from an ionized hydrogen (H-alpha), then light from an ionized sulfur (S-II) and last the light from an ionized oxygen (O-III). The final image has a resolution of 15.000 x 10.000 pixels. I shot all frames with the Canon EF 200mm f1.8 camera optics at full open, QHY9 astrocam and Baader narrowband filter set.
There are no noise reduction, star reduction or sharpening used for this mosaic. It's very well in focus due to temp compensating focuser I made for this lens. (At f1.8 the critical focus zone is about 7 metric microns.)
Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen.

Cygnus project, the grande finale
Direct link to a 2000x3000 pixel version HERE. (7,5 meg)
(Original one is ~14.000x10.000 pixels)
At top Left, a beautiful open cluster, NGC 6819 , can be faintly seen. (It's well resolved in full res. image)
Two bright objects at bottom middle are Sh2-112 and a bluish Sh2-115. At bottom Right are parts of the North America and Pelicän nebulae visible. The propeller Nebula can be seen at center left. There are many other objects in this large field.
R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
Total exposure time for all channels ~15h
Top of light exposures, there are calibration files shot.
H-a, 21 Flat frames
O-III, 21 Flat frames
S-III, 21 Flat frames
All filters:
99 Bias frames
19 Dark frames
