I make a tip-in style dovetail saddle that will allow you to balance an SCT as close as 4" from the tail end of the dovetail bar. At the same time, it provides 12" of support for the dovetail bar. This can be very useful for SCTs that are tail-heavy from cameras, flip mirrors, or heavy eyepieces.
This saddle has mounting holes for Losmandy G-11, Astro-Physics 900, and 1200. It can be used with a GM-8 if washers are used to reduce the G-11 5/16" holes to 1/4".
The tip-in feature will be useful to G-11 owners. Instead of threading the dovetail bar into the saddle from the end, you just put one edge of the dovetail bar into place and tip the other edge down. Then tighten the clamps. It is much easier than using the standard G-11 saddle, especially with heavy OTA.
See my web page for more details.
