Boris, Of course you can check does your MTOs have 3 screws fixing m42 mount, if they do, go and find T2 Nikon adapter and small screwdriver and in 90 sec you will have mirror lens with nikon mount and infinity. The hardest thing in this operation is to line up T2 adapter and lens so you can use tripod mounts on the lens properly (in level). "Everything should be easy and simple" - I agree!
