Call or email Nikon about the camera mount. I have a Nikon P5100 now. I went through 4 cameras and three camera mounts before I settled on something. You can also google Nikon digiscoping. I think there are a few forums that discuss equipment. I never did try a camera mount for an SLR. The camera fits right up to the lens and you have to remove the scope eyepiece. So I would have to choose between digiscoping or using the scope.
I have a Swarovski scope (80 HD) and binoculars (8X32). But the planets have to be aligned before I can get really clear sharp digiscoped pictures. Now I think I have about 10 good ones and 5,000 bad ones. But I go more for documentation and choose interesting. My best catch of all time is a video of an eagle attacking a coyote that is carrying a piece of deer meat across our frozen reservoir. It was at least 3,000 feet away. The quality is terrible. But you can tell what is happening.
Good luck. You will have a lot of fun with your new equipment.





This kind of looks like a snake a little.
