M13 and Hickson 44

[Gerr]

Weather window opened up for a few hours last Saturday night which gave me opportunity to go for two targets:

M13 - The Great Hercules Cluster and the Hickson 44 Galaxy Group in Leo.

Again it was the Zwo ASI 294MC Pro in action coupled with an Astronomik UV/IR Filter in my Bortle Class 5/6 back garden.

The 8" Newtonian was utilised on the HEQ5 Belt driven mount and guided by PHD2 run through APT.

Images stacked in DSS with usual calibration frames for dedicated OSC and processed in Photoshop CS2.

The 294MC Pro was cooled to -10 with default unity gain and offset.

Never done the Hickson Group before and I did struggle trying to tease the detail out!
