Quote:One other question regarding the clutches. I always leave my mount together and carry it out in the back yard. When not in use, I leave it with the clutches disengaged. What would happen if the clutches were engaged and the mount got bumped or someone moved either the RA or DEC? Would that damage the gears?Thanks,DSG

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy.

Quote:Ed:You said something interesting:"...because the Atlas has only 3 large-toothed gears between the motor and the worm whereas the CGEM has about 8 gears between the motor and the worm."Folks often assume that these are very similar mounts, other than cosmetics and motor type. It sounds like that may not be wholly accurate. Any idea why Celestron would opt for so many more gears in the drive train than Orion/Sky Watcher?Are there advantages (real or theoretical) to either approach?Thanks!- Jim

Quote:I'm looking forward to having another opportunity to use it. In the meantime, I'll be checking to see if my Celestron CG-5 hand controller is flash upgradable and if so, will probably order the NexSXW board for my Sphinx. Why not take advantage of clearly superior software if I can, right? Especially with my small scopes, knowing that the go-tos are accurate will help me find those really faint fuzzies.
