ATIK EFW2 filter wheel grub screws...

Recommended Posts

Just rotated my 460 camera on the back of my EFW2 filter wheel by slacking off the two grubs screws and retightening, as per instructions.  Easy-peasy, but then I noticed that on the telescope adaptor side, there are three little Allen screws on the filter wheel close to the adapter thread.  What do these do?   They are not mentioned in the manual but they show up on Atik’s drawing.  I could take it apart to find out I suppose, but I’d thought I’d ask here first.   Tilt adjustment maybe?
