Product Description

This universal dovetail plate fits the 75mm 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 Celestron CGEM, CGEMII, CGX, CGX-L, CI-700, CGE, and CGE Pro mounts. It is designed primarily to hold the mounting rings of longer focal length Astro Physics, Astro-Tech, Borg, Celestron, Explore Scientific, Meade, Orion, Parallax, Questar, Stellarvue, Takahashi, TeleVue, Vixen, and William Optics refractors, plus those of the larger Questar, Meade, and Celestron catadioptric optical tubes.

The dovetail has a series of 72 mounting holes on center-to-center separations of 35mm, 60mm, 1.25", 1.5" and 2", four center-line slots, and 13 center-line holes for installing virtually any configuration of mounting rings. The holes and slot are 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. Thread-in bolts are provided to act as stops to keep the dovetail and optical tube from sliding out of the mount saddle should the mount's locking knob loosen accidentally.

As a thoughtful touch, the corners of the 75mm dovetail are rounded to keep them from digging into the saddle and hanging up if the dovetails not perfectly straight when it is installed on the mount. The 0.7" thick dovetail is precision-machined of aluminum stock. It measures 19" long x 4"wide overall and is anodized black for good looks and durability. It weighs 3.25lbs

These plates are solid and machined beautifully. Will mate perfectly to your scope and probably outlive you in terms of indestructible construction. Even if you don't use it with the scope it was designed for, (sell your scope for example), the extra holes will allow it to be a versatile plate for a variety of scopes as well. It's nice to have options with a dovetail and this plate served me well for Astrophotography on my Atlas EQ-G Mount. Highly Recommended (Posted on 1/3/2019)

Typical Losmandy mechanical quality. The markings on the side really aide in balancing a tube that is removed from the mount frequently. (Posted on 10/6/2018)
