Open: Saturday, 14 November 2020, 1809 MST
12" f/8 LX600 w/StarLock
2" 24mm UWA eyepiece
1813 MST: LX600 ON, StarLock OFF, High Precision OFF.
Viewed Jupiter and four moons, Saturn and three moons, and Mars, 102X.
Viewed M33 (Triangulum Galaxy), 102X. It was faintly visible against the twilight sky.
As I had noted on the previous report, a neighbor's "greenhouse lighting" was turned on once again. The lights had not been on for several months. When I had pointed out the issue months ago the neighbor had installed some shielding, which helped a lot. Unfortunately, the light is once again leaking out.
Mounted the D850 DSLR at prime focus + focal reducer + UHC filter, focused on Mars, and locked the 12" mirror. Slewed to M33.
1847 MST: StarLock ON.
This is a StarLock autoguided image of M33 (Triangulum Galaxy), 15 minutes, ISO 6400, White Balance 5000K, slightly cropped.
1922 MST: StarLock OFF.
Viewed M33, then M45 (the Pleiades), 102X.
1950 MST: LX600 OFF.
1959 MST: took a Sky Quality reading and reported the result to Globe at Night.
