1935 MST: Viewed Mercury, 251X + ADC. About a half-phase visible.

2004 MST: Back to the bench to watch the stars come out.

2030 MST: The Milky Way taken with the iPhone using the Camera app (Night Mode, 10 seconds, 1X lens, handheld).

2031 MST: Back inside the observatory. Mounted the D850 DSLR at prime focus of the 12" telescope, focused on the star Arcturus, locked the primary mirror, and SYNCed on Arcturus.

2037 MST: High Precision ON. 2039 MST: StarLock ON.

Took the following StarLock autoguided images of Herschel 400 objects, ISO 3200. Galaxies were 5 minutes exposures; the rest were 1 minute exposures. 2158 MST: Near the end of the imaging, the sky was brightening from the rising waning gibbous Moon.
