Stellarvue R80E Finderscope Ring Mount for Hinged OTA Rings
Do you want to mount your Stellarvue 60mm or 80mm finderscope (not included) to the hinged ring assembly of your telescope's main optical tube? Then the Stellarvue R80E is what you're looking for. The base mounts on any OTA tube rings that are about 1" wide and have a pre-drilled center hole that accepts a 1/4-20" or 6mm screw. The dual ring mount has an internal diameter of 3-7/8" to accept that big, big finder and non-marring nylon-tipped stainless steel collimation screws to hold it in place! Just slide the assembly along the dovetail rail until it reaches its safety stop and secure. Using the collimation screws, align with your main tube optics and you're good to go! When the observing night is finished, just release the dual ring assemble and store. Your collimation stays fixed and you're ready for your next observing session!
