Temperature: 75°F

Session: 1757
Conditions: Clear, hazy

12" f/8 LX600 w/StarLock

1.25" 15mm eyepiece
2" UHC filter

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.

Removed the camera and viewed SN2022hrs, 102X and 163X. Nice view of M60, NGC4647, and the supernova at 163X. Then viewed M68 (globular cluster), 163X.

Attached the LiDAR Cover to the iPhone 13 Pro Max and mounted the iPhone on the 15mm eyepiece using the Levenhuk adapter.

Imaged these globular clusters, afocal 163X, using NightCap Camera (Long Exposure, Light Boost, ISO 16000, 1sec, 1 minute, 1X lens).
