This Quick Release Base designed by Astro-Physics securely fits scopes from as small as 3", meaning that it will automatically contour to fit all your scopes! It mounts onto the pre-drilled holes of your Astro-Physics refractor or other commercial telescopes that utilize the same side-to-side hole spacing. It even incorporates inline holes to make it compatible with virtually any scope / focuser combo on the market today. This is possible due to the fact that the spacing between the holes of most finder brackets is standardized, whether side-to-side or inline.
The dovetail design of this base accepts the following items:
- 10 x 60 Quick Release Finder Bracket (S1060QRM)
- 8 x 50 Quick Release Finder Bracket (S850QRM) - discontinued
- Male Dovetail Base (A3251-B and earlier versions) along with whatever accessory you have attached
- Modified TeleVue StarBeam (STARFMD) or modified Qwik Point finder, which already include the A3251-B male dovetail piece from Astro-Physics
NOTE: While the dovetail bar of the Astro-Physics Guider Bracket Kit will fit this base, it is recommended to use the longer QRBASEG for stability
You can easily use this base for either left- or right-handed use by rotating the base 180-degrees, thanks to its symmetric design. It can easily be attached to dovetail bars to further expand usefulness due to the tapped 1/4-20 center hole! The base is small enough that you will be able to leave it attached to your scope. Simply loosen the thumbscrews and slide the finder assembly out. When you pack your scope into its case, turn the scope so that the base is in a corner position.
You may want to purchase an extra base to attach to other telescopes so that you can easily swap your finder from one instrument to another. If your scope has multiple finder bracket holes, you can either have multiple types of finders on your scope or you can quickly switch your finder from one side of teh scope to the other with ease. Consider adding the Male Dovetail Base A3251-B to other finder accessories that you may have in order to make them compatible with the Quick Release Base!
Mounting hole spacing: approximately 1 3/8" (34.9 mm) side-to-side and uses 10-32 x 5/8" screws for attachment. The inline hole spacing is approximately 0.78" (20 mm). The base length is 1.35" (34.3 mm).
