Allow the scope to be parked in a reasonable location. I've seen lots of roll off roofs where the owner is trying to save money and make them too short, and then have to park the scope in some very specific, very weird direction to clear the roof. That's all fine and good as long as it actually parks perfectly, EVERY TIME.

Number 2 is one of my main motivations. The top reason is that I'm getting too wobbly to keep hauling the CPC 800 out and back for every session. Plus I waste a lot time setting up, equilibrating and re-aligning.
I've done a few measurements and six feet to the roller track should do it. My horizon is in the trees and there is serious glow to the SSE so below 25 degrees is useless.
