This was primarily a test of my telescope optics, and I can indeed see a lot of errors in this image (mostly lateral chromatic aberration, tilt and field curvature). Nevertheless, the star field is also pretty to look at.
M71 – Globular cluster

Total integration time: 69 minutes
The globular cluster Messier 71 in the constellation Sagitta lies very close to M27 (The Dumbbell nebula). M71 was long thought to be an open cluster due to its lack of a dense central core of stars, but was recognized as a true globular cluster in the 1970’s.
I experimented a bit with some new techniques for the star color and I like how it turned out. A lot different from my previous RGB work and with more color in the star cores. I stacked this with 2X drizzle (0.8X drop shrink) and deconvoluted the data to increase the resolution.
