2007 MST: StarLock OFF.

Viewed M42 (Orion Nebula), 102X.

Prepared the D850 DSLR for another attempt at imaging the James Webb Space Telescope (JWST). This night it would be farther away and so likely fainter than my attempt the previous night.

2020-2034 MST: took a short break.

Mounted the D850 DSLR at prime focus + focal reducer, focused and SYNCed on the star Betelgeuse, locked the mirror.

2039 MST: Wi-Fi ON.

Used SkySafari 7 Pro on the iPhone to GOTO the JWST.

2042 MST: StarLock ON.

Took two StarLock autoguided images, 5 minutes, ISO 6400, White Balance 4550K, exposures separated by 30 minutes. Unfortunately, I was not able to image JWST.

2119 MST: Wi-Fi OFF, StarLock OFF.

Viewed M41 (open star cluster) and M79 (globular star cluster), 102X.

2130 MST: LX600 OFF.
