| Description |
Messier 7, an open cluster in Scorpius. Named after the Greek-Roman astronomer Ptolemy, who was first to record it in 130 CE. It is the southernmost Messier object with a declination of -34.8, rising to only ~19.7 degrees high at meridian from here in Santa Fe, New Mexico. A very challenging target for my current setup. Tried to get everything tightend down and polar alignment as good as possible, but still ended up throwing out around 84% of my subs. Thankfully this is a bright region of space so the data was workable regardless!
