TAAA Eclipse Talk, Comet Tsuchinshan-ATLAS

Posted: 4 May 2024

Friday evening, 3 May 2024, before going to the observatory I participated in the Tuscon Amateur Astronomy Association (TAAA) General Meeting. I was one of eleven TAAA members who gave reports on their 8 April Total Solar Eclipse experiences. I talked about my Hometown Total Solar Eclipse Experience.

You can view the TAAA meeting on Facebook. I come on at 38:40 for about 5 minutes. There are several excellent eclipse experience reports so watch them all.

Prepared the D850 DSLR for imaging.

Viewed Comet Tsuchinshan-ATLAS (C/2023 A3), 102X. The coma and short tail were visible.

2058 MST: Dome OFF.

Mounted the D850 DSLR at prime focus + 2X Powermate, focused on the star Spica, and locked the telescope primary mirror.

2108 MST: StarLock ON, High Precision ON.

Began imaging Comet Tsuchinshan-ATLAS. It took awhile to get the comet centered in the high magnification camera field-of-view. Autoguiding was not great due to the hazy sky conditions. I finally managed to get this StarLock autoguided, prime focus + 2X Powermate image (30 seconds, ISO 12800, cropped).
