Then the issues begin ...
I wanted to test it on my Panther, which can accommodate Vixen or Losmandy plates. In terms of length, the plate on my NP is just barely long enough for the Panther dovetail. Any balance adjustment will require loosening the clamshell and sliding the tube. A bit of a risk for a DSC equipped mount.
So I thought I would try a Losmandy Universal plate - apparently not so Universal. The Tele Vue spacing does not match.
Looking at the Tele Vue plate, it appeared to be a Vixen-style. Kind of sort of. I put the Tele Vue plate back on, clamped it in the Panther head and gave it a lift test. Grasping the optical tube on either side of the clamshell, I lifted the combined unit 1/2" off the table. The 35 pound Panther head promptly separated from the telescope!
Taking a closer look, the Tele Vue plate is only tapered on one side - explaining the lack of holding power (Vixen comparison photo attached).
I think I will give this a try tonight (very gingerly of course), but I need something a bit more secure - and longer to accommodate the varying loads the scope will carry.
What do I need to buy?
