This M2 was a funny one. First of all, it never rises above 25 degrees, which is just above my southern tree line, resulting in a lot of haziness. Secondly, the clouds rolled in and left me with one (1) partial green frame which could be registered. Some shenanigans were required to get the color balance, since I didn't want to synthesize the green. So, after managing the trees, clouds and PI madness I'll take this as a small victory.
