This is from Bonney Lakes Astro Systems, the Milburn wedge folks.
Consists a 1-1/2" DT rail with a PBCM #2 piggy back camera mount (Bogen 3025 3 way head). Polished aluminum that matches their wedge. Fits 8" Meade SCT. Really nice, you can place the mount and camera anywhere along the rail to balance your DEC, then you don't need a separate balance system for fork mounts.
Asking $70 plus $8 priority mail (it's heavy).
**SOLD** auction #391, thanks John and Astromart!
