M 8 “Lagoon” and M 20 “Trifid” nebulae, August 1, 2019

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 f2.8, 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.
