On the night of July 3, 2020, I decided to shoot Saturn. The atmosphere was very stable, but far from ideal. I decided to shoot one big video with a duration of 16 minutes, so that I’m probably already collecting enough good shots. I also further increased the focal length of the telescope using an atmospheric dispersion corrector as an extender tube. Planet altitude – 16 degrees.

Below is the version with video derotation in WinJUPOS. My opinion is that with an aperture up to 203 mm inclusive, you can do without derotation if there are no large eddies or hurricanes in the atmosphere of Saturn.
On the evening of June 17, 2020, I took up a little extreme shooting of nebulae from the city. Extreme, since in conditions of strong urban exposure, the capture of diffuse nebulae without filters is very difficult. Fortunately, I am the owner of the wonderful Optolong L-eNhance filter, which only passes lines of hydrogen H-alpha, oxygen OIII and hydrogen H-beta. I had very little time for shooting, as the nebula quickly moved between the neighboring house and the tree. I am satisfied with the result, given the short shooting time – only 15 minutes. Also for shooting, I used a four-lens apochromat Meade 70 mm quadruplet apo.
