Hang in there Paul, that's a credible attempt under the circumstances. How do you feel about the collimation with the way you cool the OTA?

Clear Skies,

Thanks for the encouragement, Brian. I really am not upset and whiny. I have to poke fun at myself or I'll go crazy. I believe there is a mathematical relationship between aperture and problems and it is directly proportional one. The bigger the aperture, the more the problems...

Even though the secondary "cradle" is indexed, because I am taking the secondary out and putting it back in, I will usually recheck collimation or wait and perform collimation after the cooling. Fortunately, I haven't seen it change or lose it. Taking the camera, filter wheel and barlow in and out seems to affect collimation a lot more than playing around with the secondary to set up the Cool Edge. Installing some cooling system that is more permanent is probably going to be the way to go. And, get it permanently mounted as I planned.
