Description

First run at M101 for 2021, first time in LRGB for me.

12+hrs total integration so far, may try some Ha in due course

517x 60sec L2

85x 60sec RGB each

Improvement from last year's noisy OSC efforts on the same RC8 scope here: https://astrob.in/2tzfd4/0/ and https://astrob.in/919i8j/C/
