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!

Tokina 300mm f2.8 and Apogee Alta U16

After many years shooting with a long focal length instrument it was like a fresh air to work with wide field tool.

NOTE, images are not in scale to each other

There are some very rarely imaged objects in the the poster

Supernova remnant Sh2-221 and a planetary nebula Sh2-216. There are very few images out of them, I haven't seen any other three band NB images from Sh2-221

Photo 7 & 25, https://astroanarchy.blogspot.com/2020/03/a-two-frame-mosaic-photo-of-sharpless.html

43 hours of exposures was needed to reveal targets in full glory. There are very few images out there from Sh2-205 and even less from LBN 696.

This is a very large dim and diffused supernova remnant in Cygnus, The dense starfield almost buries faint filament structures. Extremely few photos out there showing the whole SNR.
This SNR is part of the Cygnus mosaic (Image 21).

Photo 21, https://astroanarchy.blogspot.com/2020/01/deep-in-to-my-heart-ic-1805-in-mapped.html

A very commonly imaged target but this deep exposure reveals a very dim supernova remnant just above the "Tip of the Heart". SNR can be seen at eight o'clock position in the photo.

Two massive panorama mosaics

This year I got ready two very large narrowband mosaic images.

Material for them was collected during past ten years.

The Great Mosaic of Cygnus covers now the whole constellation.

Second as large mosaic spans sky from Cassiopeia to Cepheus.

Exposure time for both of then is over 800 Hours.

THE BOOK

At 2020 we published a book about nebulae, "Cosmic Clouds 3D" We = Brian May, David J Eicher and Me. It was a pleasure to work with talented people. The idea for the book came from Brian may, the legendary Queen guitarist and astrophysicist. At the moment the book is practically sold out.
