Open: Tuesday, 22 January 2019, 1810 MST
1815 MST: LX600 ON, StarLock OFF, High Precision OFF.
Viewed Mars, 102X. Nothing impressive.
Next, I did an AutoStar One Star alignment to refine the star alignment, followed by a SYNC on the star Aldebaran. Also, tweaked the straight-through finderscope alignment.
I then prepared the D850 DSLR for prime focus galaxy imaging for my Extragalactic Supernova Project. I planned to image NGC676 and NGC772 this session.
1844 MST: Dome OFF (onto PZT).
Mounted the D850 DSLR at prime focus of the 12" telescope, focused on the star Aldebaran, and locked the 12" primary mirror.
1857 MST: the Zodiacal Light was very visible in the dark western sky.
1904 MST: High Precision ON.
Slewed to NGC676.
1906 MST: StarLock ON.
I then began imaging NGC676 (galaxy). Seeing was not good so StarLock autoguiding was bad. This was the best image I managed, StarLock autoguided, 5 minutes, ISO 6400, White Balance 5000K:
Since the seeing was so bad I decided to give up for this night.
1929 MST: StarLock OFF, High Precision OFF.
After removing the camera from the telescope I viewed M42 (the Great Nebula in Orion), 102X.
1937 MST: LX600 OFF, Dome ON.
Close: Tuesday, 22 January 2019, 1949 MST
Session Length: 1h 39m|
