So I have a C14 Edge.? I am having I think a centration issue.? I am using a Feathertouch focuser on the back end, screws onto the rear cell.? Collimation is after the scope has acclimated for several hours, Do not use a diagonal, straight through the back end.? Star at fairly high elevation.? Start at low power and work up.? The corrector was centered by the folks who sold it to me.? Using the primary mirror locks.? I am somewhat outside of the 5.75" backfocus spec, this is a visual scope.? I can get a good collimation on the OUTSIDE of focus.? Secondary shadow is centered.? Will run towards focus, just out of focus, star "ring" is evenly bright.? Go INSIDE of focus, secondary NOT centered.? So I can make myself crazy trying to even things out.? I am thinking that the primary might be tilted slightly as there is image shift when using the "factory" focus (the mirror lock are backed off, when using the factory focus), so the primary wobbles a bit.
Question is, how to square the primary to the secondary.? Anyone have this issue and what was the fix?
Thanks, Mike?
