Antares Quick Release Bracket for 80mm Finders

This is a very high-quality quick-release finder bracket with two rings for 80mm finders. Each rings includes three-point nylon screw adjustment for precisely aligning your finder. The inner diameter of the bracket is 90.4mm, so it can be used with finder tubes ranging from 70mm to about 80-85mm in diameter. All-metal bracket with an anodized black matte finish. A dovetail base (with a base curve of 9") is included with this bracket. The base will need to be bolted on to your telescope tube. This included bases will also directly fit on 8" Meade SCTs (might fit Celestron or other SCT sizes, but we have not checked). The mounting-hole spacing on the base is 1.3". Bases are also available separately with different curvatures to fit different size tubes. Antares Optical Product Number: F80DTB-9
