Astro-Tech Vixen-Style Dovetail Rail for Mounting Accessories on Astro-Tech AT6RC 6" RC

This 12.75" long Astro-Tech accessory dovetail rail mounts on top of the Astro-Tech AT6RC 6" Ritchey-Chrétien astrograph using existing holes in the scope's front and rear cells. The Vixen-style accessory rail duplicates the mounting rail under the AT6RC body and lets you mount optional accessories on top of the AT6RC. For example, you might install photoguide rings such as the #ATVR90, #ATVR110, or #ATVR125 for guiding the AT6RC during astrophotography using your own short focal length photoguide refractor.

The underside of the dovetail rail is curved to match the curvature of the AT6RC body for a solid installation. The rail has two unthreaded and countersunk 5.5mm diameter mounting holes at each end. The holes are spaced to match the spacing of the two Philips-head screws at the 12 o'clock positions in the front and rear cells of the AT6RC that help to hold the cells to the optical tube body.

The accessory dovetail rail is installed by removing the two screws at the 12 o'clock position from the front and rear cells of the AT6RC. There are a total of six screws in each of the front and rear cells, so the top pairs can be removed without any risk. Attach the accessory dovetail rail to the AT6RC using the newly exposed screw holes and the new flat head Philips-head screws supplied with the dovetail rail. Tighten the new screws firmly and you're done.

In addition to the photoguide ring sets listed above, any other optional adapter designed to fit a Vixen-style dovetail (such as the Astro-Tech #ATVA and the Losmandy #VA) can be used to mount accessories on the top of the AT6RC.

The dovetail rail is precision-machined of aluminum stock. It measures 12.75" long x 65mm wide at its widest point. It is anodized dark black for durability and to match the trim color of the AT6RC. It weighs one pound.
