After opening the observatory, I began waiting for neighbors Dennis and Wendy and their amateur astronomer friend Paul to arrive at the observatory.

1850 MST: Visitors arrived. I explained some of the history of my SkyShed POD observatory and telescope.

1907 MST: LX600 ON, StarLock OFF, High Precision OFF.

We viewed Venus, 174X. We then viewed Jupiter and three of the Galilean Moons, 174X. Seeing was not good this night.

We then viewed M42 (the Great Nebula in Orion), 102X.

Next, I pointed out M31 (Andromeda Galaxy) in the sky and how it could be seen with the naked eye even though it is 2.5 million lightyears away. We then viewed the Andromeda Galaxy and its satellite galaxy M32, 102X.

Several times during their visit I pointed out the Zodiacal Light in the western sky. I also mentioned that Gegenschein was visible from here in Oracle at a certain time of the year.

We viewed the Double Cluster (two open star clusters), 102X.

The last object the visitors viewed was the Eskimo Nebula (NGC2392, planetary nebula), 174X.

2010 MST: The visitors left. They really enjoyed visiting Cassiopeia Observatory even though it was a cold night.

I viewed M42 (Orion Nebula), 174X and 102X.

Due to the breezes and poor seeing I did not do any imaging this night.

2014 MST: LX600 OFF.
