Sergey, why did you shoot at 10 seconds with such a mount?

Yeah, I'm kicking myself for not fully figuring out guiding yet (there's sometimes an error during tracking), and I bought the mount (for the Moon and planets) cheap, not new, about 1.5 years ago, and everything was kind of rushed! I don't really have the time or the weather to just sit down and sort it out properly, but I've seen the photos people take with sub-exposures even at 1 second, so for now, it is what it is! Of course, I've managed exposures up to 3 minutes when I tried! I'll definitely dive into the settings properly later. As for M104. The galaxy is very low in the south, right in the city's light pollution—very strong glare and overexposure! There are a lot of nuances, and by the way, from September 2019 to now, I've only gone out for observing about five times!!! That's how many clear nights we've had))) Honestly, our astroclimate in the Baltics is gloomy! That's just how it is!)

Yes, from early May to mid-August, it's the season of white nights!))
