  1. Jeremy, 

    Sorry to bother you.  I noticed from a photo you posted you have a Celestron 9.25 with a refractor piggybacked on it.  I have an 1100 and I am looking at a Williams optics 73 zenithstar APO. This is new to me and a I am unsure of the mounting approach. The APO has a vixen style mount. May I ask how you mounted your refractor on your OTA? I am sure it’s really simple and I apologise for the simple question. 

    Best

      Hello Simon,

      It's actually a C11 in the pic (I do have a C9.25, which I referred to in my post, but that is not shown).

      I installed an ADM Losmandy D dovetail plate to the top of the C11 OTA. On this is fitted a ADM D Series Dovetail Plate Adapter

      The small refractor is a Takahashi FS60C which has a Tak tube cradle. The bottom of the cradle as a 3/8-inch photo tripod screw hole. I use a screw into that from the dovetail plate adapter. I suspect your WO scope might have a similar hole in it's base, if you look on the bottom of the Vixen dovetail.

      There is one disadvantage to my arrangement: it's difficult to precisely align the Tak scope with the C11. This is not a problem for me as I'm not actually using it as a guide scope, but as a wide-field imaging scope. If I needed to be able to adjust the Tak, I'd use ADM tube rings to mount it.

      Hope this helps,

      Jeremy
