1. I have a VMC200L mounted on a Sphinx SXD for primary imaging scope The VMC came with 8"CNC rings with Losmandy DUP (original owner used a G-11) but now I use the original Vixen dovetail meant to mate with the bottom of the VMC directly so I don't use the rings)
2. I have a Celestron Onyx (80ED) that has its own foot.
3. I have a Celestron Nexguide autoguider (stand alone) with 1.25" nosepiece (so compatible with the Onyx)
What will I need to mount the Onyx onto the VMC200L in order to use it as a guidescope? And how can I do it cheaply?
I was considering a 50mm guidescope (simple) but the previous owner of the Nexguide said his 500mm guidescope + 4000mm SCT didn't work well as the Nexguide does not do subpixel guiding.
