Description

Andromeda in HaOIII-LRGB.

I don't generally use differing cameras for a given image but in this case over a few nights my setups changed for the needs of other objects, and I imaged M31 while waiting for those targets to rise.

RGB was imaged on the ASI128MC at unity gain 132.

Narrow band was imaged with the ASI6200MM, 1x1 binning, at gain 200 then re-sampled to the native resolution of the 128MC. I combined all five channels into a synthetic L.

Drizzle 2x integrated for post processing then cropped and down-sampled.

Conditions:

Dec 14th OSC; SQM 20.54 clear 0C calm

Dec 15-16th Ha, OIII; SQM 20.59 clear -7C calm
