If you want to mount an F002 MRF to your Schmidt Cassegrain we have combined the large FBD shoe with the stalk that holds the MRF. It includes a beefy dovetail shoe and an aluminum stalk that has the dovetail groove for Multi-Reticle finderscopes (sold separately). The shoe with both The Stellarvue R50DA or R80DA optical finderscope ring systems so you can switch from our optical finder to the F002 MRF finder easily.
Please note: Different SCT's use different diameter and length screws in their mirror cells. As the manufacturers often state, it is important that whatever screw you use in their threaded holes, they should not thread into the cell any more than the screws you remove. Damage to the mirror could happen if the screw is too long. For these reasons we do not provide mounting screws with these parts. So when you get this part, hold the shoe up in place and determine how much longer the screw needs to be than the one you remove. Then take the screw to the hardware store and get one of that length with the same thread.
Second Note: This is for our multi-reticle finder, it is not made for our plastic Stellarvue F001 Red Dot Finder.
