Focuser assembly help!

[Danield06]

Hi,

I just recently got my Meade 6000 80mm apo. The attached focus assembly has the ability to rotate to reframe your object. I have the screw holding down the focus assembly, however, it is still able to rotate and gets annoying when I am loosening the self centering piece to remove my camera. Is this normal or does this need to break in? I can try to tighten it more but I do not want to stretch the threads. Its just annoying that when trying to remove the camera that the whole focus assembly is always rotating still. 

 

I appreciate all of the help, thanks!

Doesn’t the focuser have more than just one screw?   Maybe slightly tighten the small flat screws, the headless ones

They're usually Teflon tipped to guide the rotational movement , don't overtighten them. For £1000 I'd expect the lock screw to ... Lock. Talk to supplier and see how they feel.

It shouldn't be that loose. You can tighten the flat brass screws a tiny bit to give it a bit more friction. Both my Altair EDR scopes have the same type of focuser. What I dont like about mine is that self centering locking collar. It's far too stiff to both lock and unlock and I have to grip the focuser firmly to stop it rotating. If I wasnt using a threaded connection for imaging and I observed more often I'd ditch it and buy a ClickLock.

Thanks! I didn't even touch those screws yet. Had no idea they were for the focuser rotation. I was just using the middle one that sticks up, with the rubber tip. I will tighten the others up a little bit

That is exactly what I have to do as well. I will try to tighten the brass screws some more. Thanks for the help!
