Description

Holmberg 1  UGC 5139  PGC 27605 Dwarf Galaxy  -  This "not too pretty" galaxy was chosen to test my new ASI 120 mono tracking camera after breaking the USB connector on the old ASI 120 color camera.  The new camera worked great and the PHD tracking error was the best I have had. 

Holmberg 1 is not often imaged.  It is dim (13.66 Magnitude) and 3 arc min in diameter, so it is a push for the 620 mm focal length RASA 11.  The image was taken Bin 2 and drizzled 2x in Deep Sky Stacker and is heavily cropped.
