Last night, I tested the newly purchased ZWO ASI183MC astro camera through the sky. As the object of testing, I chose the region of the nebulae M 8 and M 20. The sky was clear, but strong winds and abnormally low temperatures limited the duration of the trip out of town. Nevertheless, in 41 minutes of shooting, I managed to collect enough material to obtain a completely adequate result. As an light pollution filter, I used Baader Neodymium IR-cut. The camera is very sensitive, the signal is perfectly pulled. Shooting was performed in Firecapture, calibration in PIPP, stacking in DeepSkyStacker. The impressions of the camera are purely positive, but the Samyang 135\2.0 ED lens did not expect to draw such a small pixel. You must either aperture the lens to f\2.8, or use a sharper lens. Autoguiding with a QHY5III178m camera worked well – out of 41 frames per minute, only a few turned out to be a bit with a shift.

On the night of July 16-17, 2019, I was able to observe and photograph an interesting lunar eclipse. As in the past year, for this we had to get to the outskirts of the city, as trees and houses interfere with the observations from the yard. The weather was unstable, about 50% of the clouds, so I had to catch the moon between the clouds. Also lightings flickered in the distance. The participants in the photo school “Foton” also participated in the observations. I took two telescopes with me – Celestron NexStar 8 SE and Celestron Omni XLT 127 on the mount Levenhuk ATZ, also 8×26 binoculars. There were other astronomy fans — Nikolai from Syktyvkar with the Sky-Watcher BK 102 Mak telescope and Alexander with a home-made 200-mm dobsian. Managed to see Jupiter, Saturn, and, well, actually, a lunar eclipse from start. In the full phase, the moon was not completely closed by the earth’s shadow; The atmosphere was very stable.
