Want to mount an SCT, Mewlon, or RC and a refractor together for simultaneous film and CCD, video and CCD, or just two CCD cameras? This is also a great alternative to piggybacking a guidescope. I've created a very heavy-duty dovetail bar system for doing that. Machined from 1" thick aluminum, they can handle larger OTAs than most other dual scope systems. Available in four sizes from 12" to 18". The bottom of the Tandem Bar has a dovetail that matches the Losmandy D size dovetail bars. So, it will work with any mount equipped with my Dove12 & Dove14 saddles, the Astro-Physics DOVELM, G-11 or Losmandy Titan.
The bar will hold two dovetail saddles, ring bars, etc. Four different sizes are available for different size OTA combinations. There is more information on my web page.
