This is an adaptor to convert the finderscope bracket into a handy quick release system. The item is extremely strong and comes with four bolts and washers (2 to connect the plate to the finder and 2 to connect the adaptor to the OTA). It has a strong clamping mechanism that will hold your finder in place well and a stop on the back of the base so it won't slide out as a security mechanism.
$100 plus shipping. This is a small item so should be minimal.
