Description

Getting back to some LRGB, where I'm less confident than my NB, and I'm more constrained by the moon. This is better than my early OSC efforts, but not 100% satisfied yet. Will keep refining. Maybe add a little Ha in due course...

Last year's OSC, 1.5hrs total: https://astrob.in/5fjax4/0/

This year, 6hrs total:
180 x 60s L2
60 x 60s Deep Sky RGB

3 sessions (nights)

Description: Closer crop, since the detail is there to use! Also a little highlight reduction to better resolve the core.
