iPhone Messier Globular Clusters
Posted: 30 April 2022
Open: Friday, 29 April 2022, 1849 MST
Conditions: Clear, hazy
1856-1949 MST: Relaxed on the observatory patio bench.
1907 MST: Sunset.
1910 MST: Took this iPhone 13 Pro Max panoramic photo (west-north-east) of the scene at the observatory.
Prepared the D850 DSLR for imaging.
1955 MST: LX600 ON, StarLock OFF.
Viewed M68 (globular cluster), 102X. It was faintly visible in the twilight sky.
2000 MST: Viewed M60 and NGC4647, 102X. Supernova 2022hrs in NGC4647 was easily seen in the twilight sky.
Mounted the D850 DSLR at prime focus + UHC filter, focused on Arcturus, and locked the 12" primary mirror.
2016 MST: StarLock ON.
After doing some framing test images, I took six StarLock autoguided images (5 minutes each, ISO 1600, White Balance 4550K). Seeing was not good and autoguiding was somewhat erratic. This is a stack of the six exposures (slightly cropped) for an effective exposure of 30 minutes.
