Hi there, After considering all the options I was offered, I concluded I could not justify the cost of sending my CP3 unit to AP to have the upper serial port repaired and have to deal with customs,

Thanks for sharing your experience Robert. I have yet to need to change my 2009 AP900 GOTO clutch plugs. Both axis move freely when the clutches are loosened. I am conservative on how much I tighten

Joe, Thanks for the link. I was hoping Ray might chime in, but it seems he already has. I shall check it out. Brett

Robert, A good description. You have helped many future plug replacements! Thank you. Regards, George George Whitney Astro-Physics, Inc. Phone: 815-282-1513 Email:

The CP3 is bone dry, nothing wrong there. On another positive note, the mount tracked well all night again as far as I can tell and had parked itself spot on. This is the second night in a row. The

The AP website shows $5615 USD...does that price change?? How long has it been $5615?

Jim No, she really doesn't need it. If she did I would make one. She actually picks herself up. Very strange to see. Here is a video of how well she gets along:
