More product information
This black-anodized Astro-Tech dovetail adapter clamps onto an Astro-Tech or Losmandy brand Vixen-style dovetail plate. The adapter lets you install tube rings, photoguide rings, or other accessories on a Vixen-style dovetail plate that is mounted piggyback on a larger optical tube. This lets you piggyback a second scope or photoguide scope on your main scope.

A single hand-tighten knob clamps the Astro-Tech adapter firmly in place on the Vixen-style dovetail, but allows the adapter to be quickly repositioned along the dovetail so you can balance or change accessories as needed with no tools required.

A series of nine unthreaded 6.9mm diameter mounting holes are drilled into the adapter in a square pattern, as can be seen in the photos. The spacing of the mounting holes is shown in the engineering drawing in the feature image below. These holes allow you to use 1/4”-20 or metric bolts to mount virtually any finderscope ring, off-axis photoguide ring, ball-head camera mount, etc., on the adapter.

The holes are countersunk on the underside of the adapter so that the mounting bolts holding the accessories will not interfere with the dovetail plate. The adapter measures 2.72” wide by 2.5” long fore and aft by 1” deep. The height from the top of the dovetail plate to the top of the adapter is 0.5”. The adapter weighs 6.4 oz.

These adapters really come in handy. I've used these to connect mini guide scopes as well as digital cameras (just using a 1/4" screw up through the bottom). The Astro-Tech version is built a lot better than the ADM version on this part.

Be careful tightening the screw. I've stripped the two of the 'tops' off.
