It turned out beautifully! And why with 10-second exposures? If longer, do the stars get overexposed?

Thank you very much! I set the gain to a level with less noise, but it was quite high, the atmosphere deteriorated, guiding quality dropped, and as an experiment I reduced the exposure time. I also plan to try lucky imaging with exposures around one second.
But honestly, I didn't like the image — it could be better, there's room for improvement! I kept it for the record.

Understood, thank you for the answer!

The quality seems decent to me: stars are round, color is good, and the cluster didn't turn out flat :) It's pleasant to look at.

A bit overinflated, the potential there is considerably higher. There are also a few faint galaxies nearby that could be worked on better—we'll gradually work on that. Overall, of course, they are all beautiful when you imagine these gigantic star islands! Always a delight!
