Astro-Physics Dual Radius Base- Quick Release Bracket and ACC
This dual radius base is designed to securely fit scopes of all diameters, incorporating radii for both less than 6" and greater than 6" diameters, so that it will automatically contour to fit all your scopes. It mounts smoothly into the pre-drilled holes of your Astro-Physics Refractor or other similarly designed commerical telescope that utilizes the same side-to-side hole spacing (see dimensions below). Fortunately, the spacing between the holes of most finder brackets is standardized.
Although the base is assembled for right hand use initially, it is easily adjusted for left hand use by moving the stop screw to the opposite position and rotating the base 180°. Furthermore, the base is small enough that you can simply leave it attached to your scope with minimal issues; Simply loosen the thumbscrews and slide the finder assembly out. When you place your scope into its case, turn the scope so that the base is in a corner position.
IMPORTANT:The mounting hole spacing is approximately 1 3/8" (34.9 mm) side-to-side and uses 10-32 x 5/8" Phillips Pan Head screws for attachment. The base length is 1.35" (34.3 mm).
