Does any one know if Bobs knobs will work on Celestrons Fastar compatible secondary mirror?

I have Bob's Knobs on my N11GPS (with Fastar) and they work great. After installing you leave the screw cover in its rotated position. The cover is cosmetic only and it looks fine in the open position with the knobs installed. It actually looks like it was designed to accommodate the knobs.
If your scope gets a fair amount of jostling then I would say that the screws need to be somewhat tight. That's probably the reason that the manufactures make them so tight. New scopes have to endure shipping across country or maybe to another part of the world.
Bob's knobs do afford a good grip and it IS possible to make them very tight, if you so desire. I personally tighten the knobs only moderately and have not had a problem with losing collimation.
Bob has knobs for many different scopes, just be sure to specify the correct ones if you order. Just follow his very simple instructions and I think you will like them, I do.
