Review & Description

Astro Tech Universal Dovetail Plate for Losmandy "D" Style Mount Saddles - 7.9" Long - Astro Tech part # ATDUPSB

This black Astro-Tech 7.9" short universal dovetail plate fits the dovetail slot of the D-Plate saddle used on current Losmandy G11, HGM Titan, and GM-8 German equatorial mounts. It will also fit older GM-8 mounts that have been upgraded to the wider-dovetail G11 saddle plate, as well as fitting Celestron CI-700, CGEM, CGE, and CGE Pro mounts.

The Astro-Tech short universal plate is designed primarily to hold the mounting rings of shorter focal length Astro-Tech, Tele Vue, Parks, Takahashi, Vixen, and Meade refractors. It will also hold the mounting rings of the smaller Astro-Tech, Questar, Meade, and Celestron catadioptric optical tubes.

The dovetail has a series of 19 un-threaded 6.9mm diameter mounting holes for attaching rings and other accessories using 1/4"-20 or metric bolts. One hole is on the plate's center line, plus there are 9 pairs of holes on 60mm centers extending the length of the plate. The engineering drawing in the feature image below shows the spacing of the mounting hole pairs. There is also a 0.25" wide x 5" long slot on the plate's center line. Its location is also shown in the engineering drawing. This combination of mounting holes and slot allows you to install virtually any configuration of mounting rings.

The holes and slots are all countersunk on the underside of the dovetail. This assures that the bolts holding the mounting rings will not protrude and keep the dovetail plate from sliding back and forth in the mount saddle for balancing. As a thoughtful touch, the corners of the dovetail are slightly rounded to keep them from digging into the saddle and hanging up if the dovetail is not perfectly straight when it is installed on the mount.

There is a 1/4"-20 thread hole at each end of the plate. This lets you thread 1/4"-2
