Milky Way Globular Clusters

Posted: 7 October 2026

Friday, 2 October 2026, was clear, but strong wind kept me out of the observatory. Same for Saturday, 3 October, and Sunday, 4 October. The strong wind calmed down on Monday, 5 October, but clouds returned. Monday evening's sunset.

SYNCed on Antares. Prepared the D850 DSLR for imaging.

Used SkySafari 7 Pro on the iPhone to GOTO globular clusters for my Milky Way Globular Clusters Project.

1911 MST: StarLock ON.

Imaged the following globular clusters, StarLock autoguided, ISO 6400. All were small, faint, and very low in the southwestern sky. Conditions were not ideal.

Then mounted the D850 DSLR at prime focus + focal reducer. Used SkySafari 7 Pro to GOTO Asteroid (52665) Brianmay, Mag. +19.7). I suspected that conditions were not good enough to image this faint asteroid, but I tried. During the one hour between exposures I relaxed on the observatory patio bench and enjoyed the night sky. Unfortunately, I was not able to get an image of the faint asteroid.

2018 MST: Wi-Fi OFF.

2125 MST: StarLock OFF.

Viewed Saturn, 102X.

2133 MST: LX600 OFF.

2142 MST: Took a Sky Quality reading. Did not report it to Globe at Night as the cloud cover had increased.
