Astro Anarchy gets published, the cover picture of an Official Vatican Observatory calendar 2019



My photo of the Sharpless 115 (Sh2-115) and a planetary nebula Abell 71 get selected as a cover photo of an Official Vatican observatory Calendar for the year 2019.

A Square Degree of Birth and Death

This photo shows  about one square degree of sky from the constellation Cygnus. In this photo, there are both, birth and the death. 
The blueish area at middle up is a stellar nursery, new stars are born there as an ongoing process. 
The blue dot at lower left is a planetary nebula Abell 71. The star has consumed all of its hydrogen resources and then blowed out its outer layers.

Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen.

The Giant Cosmic Squid, Ou4, scale in the sky and a zoom in series

Sometimes it's hard to understand the actual scale and locations of cosmical objects from a photograph. I tend to shoot same objects with a very different focal lengths usually from 200mm up to 3000mm. Form that image material I'm able to build "zoom in series" of the cosmical objects. By that way it's easier to understand the actual scale and location in the sky.

Grande mosaic of Cygnus in visual colors, 18-panels, 150 hours and 22 x 14 degrees of sky


Yesterday I published a mapped color version of this nebula complex, here is the version in visual spectrum.

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 Natural color palette from the emission of ionized elements, R=Hydrogen + Sulphur, G=Oxygen and B=Oxygen + 10% Hydrogen to compensate the missing H-beta emission.

Wonders of Swan

I have made a collection out of the photos I have shot from this area of the sky. I have used 517 hours of exposure time to capture details from Cygnus between 2009 and 2018. I used this material to update my mosaic image of the Cygnus constellation.

Chinese Dragon Nebula 
Click for a large image

The very large, 18-panels, mosaic of the Cygnus was my main work at Autumn season 2011.
I named it to the Chinese Dragon Nebula due to reason seen in the image above.
Image spans 22 degrees horizontally. (22 degrees = 44 full Moons side by side in the sky)
