Description

A very short stack of unguided 30-second sub-exposures. The sky background, not surprisingly, was a little noisy so I intentionally set the black level low to clip the noise, which is reflected in the histogram. No darks, bias or flat frames but I did use long-exposure noise reduction.

The Meade LXD55 SN6 is a 6-inch f/5 Schmidt-Newtonian.
