Can anyone comment on the efficacy of the HOTECH Advanced CT Laser Collimator?
Do you use one? Have one? Had one?
Can it be used on a Celestron C-11 that is NOT Fastar/Hyperstar compatible? In other words, do you need to be able to remove the secondary to use the Collimator?
Can it help with centering/rotating the corrector plate?
My collimation is about as good as I can get it with bright-star-out-of-focus, and I still have slightly oblong stars. Could be a flexure issue, but I'd like to eliminate collimation first.
I'm considering getting one but I always respect input from CN experience.
