I have several long Nikon F-mount lenses and can use them like a spotting scope when looking through the rear of the lens. Is there an eyepiece or adapter made to attach directly to Nikon F lenses for visual use, and are there any compatibility limits?

Yes, there exists a Nikon Lens Scope Converter:

However, this item is no longer in production, so you need to find one second-hand. Read the description carefully, since it will not work with all lenses. It works with all pre-AI, AI, AIS, AF, AF-D, and AF-S lenses EXCEPT for the "G" lenses which lack aperture controls. "G" lenses automatically close to minimum aperture when removed from the camera and the lens scope converter has no way to open them up.
You can also make one yourself, as described here:

Yes. Nikon made a Lens Scope Converter that lets certain Nikon F-mount lenses be used visually with an eyepiece-style setup. It is discontinued, so you would typically need to find one used.
Compatibility matters: according to the community answers, it works with pre-AI, AI, AI-S, AF, AF-D, and AF-S lenses, but not with Nikon G lenses. G lenses lack an external aperture ring, so when they are off the camera they stop down to minimum aperture, and the converter cannot reopen them.
If you cannot find the Nikon converter, a DIY adapter approach is also possible, but results and compatibility will depend on the lens and the adapter design.
So the short answer is: yes, but you need a Nikon Lens Scope Converter or a custom solution, and you should verify that your specific lens has manual aperture control.
