Saturday July 30th Black Star Canyon star party

July BSC star party should be great, if it does not rain!!!

Starbecue on 7/30/16!
Barbara Toy |
Our annual Starbecue potluck party will be the next Anza Star Party, on 7/30/16, next Saturday. It will be at the club observatory in the shade on the east side of the building. Bring a dish for about 6-8 people to share. We'll have the barbecue going, so you can bring something to grill. The club will provide plates, tableware and bottled water. Bring a chair if you want a place to sit. We'll be setting things up starting around 5:00, and plan to eat by around 6:00 - hope to see you there!

Kuhn Telescope Back In Action
Barbara Toy |
Thanks to the efforts of Pat Knoll and Trey McGriff, the Kuhn telescope is back in operation, with a new control cable, dec drive that has been cleaned and re-lubricated, and a clean mirror. We expect that it will be operating for the next star party, and hope that, if you are out at Anza for the Starbecue, you'll stop by the observatory and take a look through it!
