I am having the same problem I saw on this thread (https://www.cloudyni...vel-what-to-do/ by vkhastro1) but I am not finding the same solution.
My 86 year old father has asked me to take over his observatory. Tonight I hefted up his C14 onto the GEM for the first time. The mount is a bit over my head. Whew. I am not sure which C14 model I have but interesting to see it has a Fastar secondary mirror system.
The factory focus knob only turns a half turn or so and only serves to move the object around in the view finder.
I seem to only have two mirror lock screws with the black thumb knobs and they are loose. There are no apparent obstructions of the main mirror as seen through the corrector. I pulled the rubber focusing knob off, pulled out the end screw and threaded the bearings all the way off. The remaining threaded rod is rock solid, does not budge. Should it move?
I would love to find out there are some other mirror locking screws, but I sure do not see any.
Thoughts or advice most welcome.
