I then viewed Saturn, 102X.
1830 MST: When I viewed Jupiter, 102X, I could see that the moon Europa was just beginning a transit of the Jovian disk. I watched it for awhile.
Next I mounted the D850 DSLR at prime focus + focal reducer + UHC filter, focused on the star Altair, and locked the 12" primary mirror.
1850 MST: High Precision ON.
Slewed to NGC7000 (North American Nebula) to image it for my Herschel 400 Catalog Astrophotography Album.
1854 MST: StarLock ON.
I did some framing test images to best center a portion of the large North American Nebula in the field-of-view. The top image image was taken in 2020 with a piggybacked DSLR and shows the entire nebula. The next photo shows what I imaged this night (5 minutes, ISO 6400).
1941 MST: StarLock OFF.
Viewed Jupiter, 102X.

1959 MST: Took a Sky Quality reading.
