Various thoughts and activities related to my amateur astronomy interests including telescope making and observing. Plus other stuff that may be on my mind.

Secondary Ring Started!
This past Sunday, I braved the cold and started on the secondary ring. I used the brackets made by Dennis at Dobstuff.com and they worked perfectly! The ring is made of 3/4" Baltic Birch plywood and is 21" in diameter. The inside of the ring is 17" in diameter. I will probably have Dennis make a new focuser board because I marred this one up from drilling holes. I still attached it to the ring to get an idea of how it will look.
I have the places marked for the Moonlight truss system. I hope to finish the ring over the next week. Then it will be time to work on the mirror box.
