Can anyone tell me what these two screws are on the top of my Crayford focuser on my Vixen ED80SF? One directly behind the finder bracket and the other on the opposite side. I thought all locking and tensioning was done on the underside of the focuser with those screws. Thought I'd ask since I cant find the answer after searching on my own.

Those two screws hold a pressure pad in place on the opposite side of the focuser from the Crayford rod.

There is a curved plate with 4 ball bearing inside the focuser that supports the draw tube. Those screws hold the curved plate in place.

Do you like your Vixen?

So far I’m loving it. In all honesty I’ve only had it out once for a couple of hours but I have no complaints other than getting used to the reverse image straight through finder. My Mak came with a straight through correct image finder and then I recently upgraded that to right angle correct image finder. Other than a learning curve with that, I’m completely happy with my purchase.

Glad you are enjoying your ED80SF. The f/7.5 optics of that scope are time-proven and highly regarded. Great choice in a grab-n-go!
