I just recently took a teaching position at a local community college. We have a virtually mint Celestron Nexstar 8 that, as far as I can tell, has had almost no use. Probably because of this, the center support post and accessory tray are missing. I don't need the tray, and it doesn't figure into the tripod stability, but the post does. I am trying to fabricate a new one (we have the machining capability to do it here), but I need some help with dimensions. Specifically, the thread of the post at the top where the rod enters the mounting plate of the scope, and the length of the rod. The rest I can make work. Thanks for any help you can provide! Robert
