There were special visitors this night: Dr. Chad Tolly and his friend Brian Sivill from the Prairie Astronomy Club.

We did a lot of talking and sky watching during their visit.

1818 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed Venus, Saturn, and Jupiter, 102X.

1900 MST: I began preparing for more afocal imaging tests with a new iPhone adapter.

Viewed the Double Cluster (open star clusters), 102X and 81X.

Took this iPhone 13 Pro Max afocal 81X image of the Double Cluster using the iOS app NightCap Camera (Long Exposure, Light Boost, ISO 32000, 1sec, 1 minute, 1X lens).


I ended my afocal adapter tests. I will post a review soon.

Viewed the Double Cluster, 81X and 49X.

Viewed M31 (Andromeda Galaxy), 49X, and M33 (Triangulum Galaxy), 102X. We then viewed M1 (Crab Nebula), 102X, low in the eastern sky.

We then chatted more about a lot of different topics. We saw several meteors, many of which were likely from the rare Andromedid meteor shower.

Clouds were increasing.

2120 MST: The final object viewed was M42 (the Great Nebula in Orion), 102X. Clouds hampered the view.

2122 MST: LX600 OFF.

2125 MST: Although hampered by clouds, I took a Sky Quality reading.

2130 MST: The guests departed. They had a wonderful time visiting Cassiopeia Observatory.
