Astro-Physics QRBASE Base for Quick Release Finder Brackets
This base mounts onto the predrilled holes of your Astro-Physics refractor or other commercial telescope that utilizes the same hole spacing. Fortunately, the spacing between the holes of most finder brackets is the same. The dovetail design of this base accepts these items:
10 x 60 Quick Release Finder Bracket (S1060QRM)
8 x 50 Quick Release Finder Bracket (S850QRM)
Male Dovetail Base (A3251-B and earlier versions) along with whatever accessory you have attached
Modified TeleVue StarBeam (STARFMD) or modified Qwik Point (QWIKMD) finder, which already include our part #A3251-B male dovetail piece
Although we assemble the bases for right-handed use, you can easily move the stop screw to the opposite position and rotate 180° for left-handed people.
The base is small enough that you can leave it attached to your scope. When you place it into the case, position the scope so that the base is in a corner position. Simply loosen the screws and slide the finder assembly out. You may wish to purchase an extra base to attach to other telescopes so that you can swap your finder easily 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 have the ability to quickly switch your finder from one side of the scope to another.
Please note that this base was designed to fit on mounting surfaces with diameters approximately 6" or greater. If you are attempting to attach this base to a 130mm f6.3 Gran Turismo, please refer to the Extra Base for Quick Release Bracket, Small Radius, listed below. Note that the dovetail slot is the same for both of these bases.
The mounting hole spacing is approximately 1 3/8” (34.9 mm) side-to-side and uses 10-32 screws for attachment. The length is 1.35" (34.3 mm) .
