Question about Celestron Advanced C9 1/4-S 11045 (555 x 235mm) Telescope
When I attach any component ie; adapter, diagonal, extender etc to the visual back, the whole tube rotates with the equipment. This causes the eyepiece and all to flop down while observing at an angle. It is evident that the baffle tube / visual back base has worked it's way loose. How can I re-tighten this? If dismantling the scope is required is there a locking nut or grub screw responsible? Any recommendations would be helpful.
Hi David, the visual back should thread on to the rear cell of the OTA but on the visual back there should be a screw to lock in you 1.25" accessories.
