Re: AP1100 park position question

IIRC they sell through distributors. Contact them and ask.

I have found the best deals on eBay. I set up an automated search and check out the new auctions as they are put up.

The company is Linak out of Kentucky and the columns I used were the DL2 2500 Newton rated.  My original ones were rated at 1000 Newtons each when used with a non AP mount.  With the AP1600 and 150# of equipment on the dual column setup, I changed to the 2500 Newton thrust each – 5000 Newton total thrust.

Lymax columns. A lot cheaper to buy Lymax off of Ebay or wherever and make your own telescoping pier.

I have used Park 4 for several years for exactly the roof height issues that you are evaluating.  This is for a 1100 mount with a 14 CDK scope.  There have been no problems.

I have a PierTech height adjustable pier (  When I need to tinker with equipment, I lower the mount and move it to P3, where it clears the roof. To remove equipment, I loosen the clutches (older style 1100) and rotate/lower the OTA to a separate support table before loosening the dovetail.  I normally leave the pier at almost max height, in order for the roof to clear on opening.

The adjustable piers are actually from another company, but I have forgotten the name.  I think Chris Erickson has these.
