Description

After about a year and a half hiatus I’m back to doing LRGB imaging (but keeping a one-shot color camera for comets and nights I’m feeling lazy).

This is a 1 hour integrated image (5x3 minute for each filter - L, R, G & B). Camera was a ZWO ASI1600MM-Cool and ZWO filter wheel and filters. Scope was an Astro-Tech AT115EDT, an 115mm ED-triplet APO with a field flattener attached to it. The imaging scale was 0.96 arcsec per pixel which, while extreme for me, resulted in no images being discarded due to tracking mishaps.
