Winter must be on it's way, because I'm getting the bug to design and build again!

This is my sketch for a possible configuration. I've been playing with lots of details and attributes, and this is the design that seems to appease all of my senses. 10" x2 should be about as bright as a 14" scope. 1250mm fl will let me achieve at least 2 degrees using 2" eyepieces. F5 will be just at the edge of coma forgiveness when aligning the two separate optical paths. Finally, it's about as large as I can envision going so that I can still view at zenith, without standing on a stool. This is obviously an early stage mock-up, and open to plenty of modification before the build begins. The scope will include active cooling, active dew prevention, and, of course, an accessory drawer.

Hahahaha! I just realized I named the helical focusers in that sketch "kinematics" instead of "Kineoptics". Physics class fresh on the brain! :lol:
