Nikon DSLR Standard T-Ring - 42 mm

Fits securely to front of my F-mount Nikon D800. High quality; threads smoothly onto adapter, fits snugly in image train and keeps sensor square to focus plane. Would recommend to anyone looking for a t-ring for a 1.25" setup. Will not allow image circle to cover full sensor, but works fine with DX Crop or smaller.

I was in need of help to arrive at 55 mm of back focus so I called Stellarvue and talked with Vic (owner) he spent considerable time with me on the phone calculating exactly I would need given my different cameras and filter wheel combination. Great support - the extenders, variable extender, and DSLR T-adapter are just exceptionally crafted! I needed these to outfit my SV70T refractor that I recently purchased! So pleased!

I bought this adapter so that I would have one for each of my scopes. Now I'll be buying another to replace the other brand I have as the positioning adjustment of the Stellarvue is far superior.

Bought for my Nikon DSLR and works great.
