Tandem16 with Takahashi TSC 225, Astro-Physics 130 f/8.35, Mountain Instruments MI-250 GOTO

The Tak is mounted on an AP Dove8 saddle. The 130 is mounted on my Dove12.
A Dove12 with small knobs is mounted on the MI-250 GOTO and holding the Tandem16.

Another view of the same setup.

With this much space between scopes, the OTA can be loaded into the rings after the rings are mounted.
If the OTA is mounted into the rings before mounting in the saddle, the two scopes could be much closer.

Tandem14 with Intes MK-67 & Astro-Physics 130

Tandom Bar with a Dove12 mounted using the center holes (left) and a Dove14 mounted using the offset holes. This setup would be for a tail-heavy SCT and a refractor.

Astro-Physics 10" Maksutov-Cassegrain (left) and Takahashi TSC 225 (9" f/12 SCT) (right). I thought this would be more than the MI-250 GOTO could hold steady, but wanted to see how the prototype Tandem Bar would do with such a heavy load. I was surprised that both the bar and the mount handled the two OTA's as though it only had one. While looking at Jupiter, at about 300x, the damping time was less than 2.5 seconds.

Astro-Physics 10" Maksutov-Cassegrain (right) and Takahashi TSC 225 (9" f/12 SCT) (left). I estimate the load to be somewhere between 65 - 75 lbs. It took 65 lbs. of counterweights to balance it.

This view shows that there is room for a large SCT.
