Judging by the photo, the stars have been found.
You need to experiment with your camera, for example, take 30-second exposures but with a gain of 252. If there is overexposure, then reduce the exposure time further, or conversely, increase it if there is clearly not enough light.
For future reference, write to me on the forum olega66.

Alright, today I'll give it a try. I stitched the images in Siril—the others couldn't handle it, though Siril is a bit complicated. Also, with the Sky-Watcher Dob 130/650 Retractable Virtuoso telescope, which has a helical focuser, focusing is really tough; it always feels like the sharpness is slipping away.
