Question about Celestron CG-5 Mount Telescope
When I loosen the RA lock, I can't rotate the RA axis. It seems fully engaged with the motor drive and won't budge. The motor drive seems to work normally and will rotate the RA axis.
I had one come in like this. AS you say the RA axis should be free to rotate in the RA housing when the clutch lever is released. The cylinder that the worm is machined on is binding on the axle. This doesn't overly effect normal tracking, but makes gross adjustments impossible. The only solution is to tear the mount down and finish the parts to eliminate the interference. Google astronomyboy for the how to. I have to warn you that I had to heat the cylinder and axle in the oven at 250 for 30 minutes before they would separate. don't use the wife's good oven mits!! When I finish these parts I use Soft Scrub (w/o bleach) as a grinding compound. It's basically bicarb in a jell. HTH, Geo.
