Moon, Barnard Objects, Satellite

Posted: 6 October 2024

Although the nights were clear, I did not open the observatory on Thursday, 3 October 2024, and Friday, 4 October. Thursday night I attended a special Indiana University Astronomy Department alumni event. Friday, I was at Kitt Peak National Observatory for a special night of viewing using the WIYN 3.5 meter telescope.

Open: Saturday, 5 October 2024, 1755 MST

1759 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the Moon, 102X.

Viewed Venus, 102X.

1842-1915 MST: Relaxed on the bench and watched the stars come out.

1916 MST: High Precision ON.

Observed, or tried to, the following Barnard Objects (dark nebulae), 102X: B186, B313, B102, B314, B103, and B188.

Mounted the D850 DSLR at prime focus + focal reducer, focused on the star Altair, locked the 12" primary mirror, and slewed to the first Barnard Object to be imaged this session.

1954 MST: StarLock ON.

Took the following StarLock autoguided Barnard Object images (30 seconds, ISO6400).

2025 MST: When I first imaged B188, guided was not good. A flashing satellite that photobombed the image was the culprit.

2035 MST: StarLock OFF.

Viewed Mirach's Ghost (NGC404, galaxy), 102X.

Viewed Andromeda Galaxy (M31), 102X.

Tried to observe Stephan's Quintet, 102X. Unfortunately, the galaxies were too faint and too small to be seen in my 12" telescope on this night. Fortunately, I had observed them using the WIYN 3.5 meter telescope at Kitt Peak on the previous night.

2047 MST: LX600 OFF.

2104 MST: Took a Sky Quality reading.
