I have a Century Optics Duplikin II that I was hoping to mount to a Nikon D100. Unfortunately, there are no f-mount to c-mount adapters. Does anyone know how I might be able to make this happen?
unfortunately I doubt that is going to happen easily. The FFD (flange to film distance) of C mount lenses is usually 17.52mm (or 20.76mm for Bolex RX lenses) and the F mount FFD is 46.5mm. Unless you buy or build some kind of relay optics there is no way of forming an image on the D100 sensor. Moving the lens farther in is no option either as the mirror will then hit the lens. AFAIK there were versions of the Duplikin for 35mm still cameras. I didn't even know there was a C-mount version of the Duplikin II!

You're right, there isn't a c-mount version of the Duplikin -- I miswrote. What I have is an M42 mount. I'm hoping I can adapt it to the Nikon (without any insurmountable focusing issues) with something like this:
