physicsdude2014 asked:


I have an old Meade lx emc sct telescope and the motor drives it too fast. It goes 5 minutes of right ascension too fast per hour. I called Meade and all they would tell me is to send it in or do an exchange program for another telescope. Is there any way to adjust it so that it moves at the right speed by using weights or something?
