I like it, but it's a bit noisy.

Yes, that's right, I overdid it. I'll reassemble it when I have some free time.

I want that too. I shot with a color camera and an L-eXtreme filter, almost under dark skies, and of course I didn't accumulate as many hours, but I'm hoping to gather more this summer and get a super result) For now, here's this: https://vk.com/album5413507_294885354?z=photo5413507_457273914%2Falbum5413507_294885354%2Frev Turns out it's actually pretty decent.

Nice! And the center isn't a blob, unlike mine. But when shooting such objects, a narrowband filter probably makes the difference.

The details came out great! Awesome!

Does the Juwei-17 handle the one-meter tube well?

Thank you! I think I can still fine-tune the settings a bit, and it could really use a longer guide star. Roughly averaging, the tracking error is about 0.65-0.8 arcseconds per 4-hour session. But again, I haven't had it for long; I need to tinker with it more. That said, it tracks confidently and doesn't struggle.

0.8 is very good. Thanks for the reply and clear skies!
