Description

Tonight I could grab a few more UHC subs for my Medusa project ; not enough yet. But I took proper flats - first time... So, as the moon was rising bright in the sky (still 94% illumination), I thought "lets give it a quick try at M51, and see... in quasi B&W treatment...

VERSION B : 15 broadband subs mixed in. Humid sky created excessive orange light, hence the strange color balance... Will need dry nights and/or narrow band.
