Description

My first attempt at a globular cluster. I used very short subs (30s) due to the heavy moonlight, and only got 30 minutes of data before the clouds came in.

There is less color in this image (especially blue) vs many other versions I've seen -- likely due to the short subs and/or short total integration time. I'll try to go deeper at some point.

Description: Re-imaged as RGB with ASI1600MM, 109x120s, gain 139, temp -10C. This produced far more blue stars than the original OSC version (mostly yellow). Not sure which is more accurate.
