12" f6 Newtonian on my very old Starliner mount. Rotating rings are 14" lazy-suzans. This is my best performing scope.

Larry, that is a super good looking pipe mount!
But what are the straps going below the deck for? A counterweight?
Thank you! The 8" f11 stays outside all the time, so the straps fasten a canvas tarp to keep the weather off when the scope is not in use.

Nice scopes Larry, love the cassegrain
Thank you! I have spent a lot of time on it. I re-figured the primary a few times, and made a few new secondaries. Each iteration is a slight improvement. The f3 primary is demanding of surface accuracy and the whole system needs close alignment. I enjoy the challenge, but when I just want to look at stars, I'll use a long Newtonian.

That is a nice collection Larry! Guess I can post my most recent. Poor camera pic from this evening. 103mm F15 Jaegers lens. I machined the lens cell, rear cell and the finder.

bemms; the down angle shot your scope makes it look like a 50mm table top scope, 
After I read the size and make I did a double take

This is my 'Little Dipper' project, about one week into making sawdust. The composite pic shows the primary end and my method of mirror attachment, as well as the 'tube' next to me for scale. I just lightly pressed together the poles and parts to see how it was coming along. Oh, in case you're wondering, it's going to be a 6" f/8 using the old Synta mirror from Mighty Mouse, pictured in my avatar.
Thanks to my friend Brian for inspiring me to build this scope. I'm really enjoying the project.

The Yard Scope, built in 1992. It is a 36" f/5. Photo taken at the '94 WSP.
The guys in the photo (L-R) are Jack Newton, Richard Berry, and Don Parker.

Actually, not at this time, although the base plate is center punched should I want to cut a hole and maybe install a fan at a later date. Humidity is the biggest problem we have in the everglades and the open design and use of wood will immensely help. There is ample space between the base plate and the mirror cell for air flow. We get nice ocean breezes that keep the air moving, and we also use box fans to blow the mosquitoes off us which also circulates air around the scopes.

This is my 12" f/6 Newt that I made in 1997 and cost only $300. This was because I scavenged around for two years for stuff. Ground and polished by me.
And yes, this made S&T in 1998 or so. I sure was looking better and doing a lot better in 1997!
