Wow. Look at all of those stars. I don't think I've ever seen a single 10 minute exposure so perfect.

Thanks, I wasn't expecting such round stars, it was a "let's try a 10min..." after running a 50 frames at 180sec each.
If tomorrow I get a similar night, I will attempt a 15/20/25 min etc... to see when the star trails arrive :P

I'm impressed by the rounded stars... Excellent image... Can you please advise more about your telescope and its configuration? what do you use for field flattener to get peripheral stars rounded as the central ones? Also, can you describe the light pollution in your location and observation conditions?
Clear Skies!

I have an HEQ5 pro which I've tuned a while ago.
The telescope is an old William Optics Megrez 72 with with an OVL Field Flattener and a Zwo OAG + QHY5L-II-M guide camera.

As for light pollution here... next to none.
