B33 Horsehead, Partial Red

Start of B33 Horsehead for this year.  11 300-second subs in Red light.  Only 11 subs (less than an hour) because of a series of mount problems before acquisition started, resulting in running out of time – target sunk behind neighbours houses after 11 subs.

11 x 300 subs, binned 2×2, Red filter on QSI583wsg, on AT8RC, on G11, autoguided by Lodestar. Stacked and sum-combined with CCDStack.
