Description

A closeup of the Sh2-37 complex and its adjacent reflection nebulae. Note the purple hue of Sh2-37, a mixture between red Ha and blue dust components.

The scope was a Boren-Simon GSO Newton I could lend from my friends at the WAA club who build an observatory at Hakos. I spent an Octo focuser and took the GPU corrector to photograph at f/4. The mount was a CGEpro which worked fine but had the strange habit of just stopping tracking at meridian.

LRGBHa 30-9-7-7-8 subframes, each 3min at -20°C zero gain.
