Description

I've used this target as something to point the telescope at while waiting for the thing I'm really interested in coming up over the course of about 2.5 months.  I'm very happy with the amount of OIII emission that I was able to get which allowed the oxygen envelope of the Crescent to really pop during processing.  Images were collected over 9 nights from September 12 through December 2, 2021.  Chroma 3 nm filters.  All exposures were 6 minutes each.  Total integration time = 19.9 hours.

SII:  6.0 h
Ha: 6.0 h
OIII: 7.9 h

Gain 100, Offset 50, -10C
