Description

First run at M51 for 2021, first time in LRGB for me.

Also first time using Celestron OAG, ASI1600/ASI174 on the AT8RC for this year's galaxy season.

2hrs total integration only so far, so hope to double this before calling it done. Still a bit noisy, but pleased the collimation looks pretty good on this challenging scope.

Disclosure: this interim version uses Topaz Denoise AI to cover up noise given the relatively short integration.
