I recently acquired a property with a 15' ProDome that contains a 12.5" Parks Optical observatory series Newtonian scope and GEM. The clock drive has a cracked hub gear. Does anyone know if there is a source of replacement parts for this since Parks optical is no longer around? i have attached a picture of the crack which is right where the set screw secures the hub gear to the RA shaft.. Don't know if it is possible to repair this or if there is a compatible clock drive replacement available? Also may consider a new "go to" mount if I can not repair the clock drive; so any suggestions for repair, or options for replacement of clock drive, or recommendations for a reasonably priced go to mount for this scope would be appreciated!
Thanks - Jim
