What kind of star tracker can be used for this telescope?

I have my 550 svbony triplet on a sky watcher eqm-35 goto mount. The eqm-35 mount is more than capable of handling the weight along with all the astrophotography Equipment I have on it.

Is there an adapter for connecting a nikon f-mount dslr to this?

Yes. On the svbony website is the SV194 Photography Adapter for Nikon Cameras. The one from svbony has both m42 and m48 Size threads. You can find many different brands if you search for "T-mount adapter for Nikon F-mount"

Where do I get a 2 inch T mount for nikon?

Have you tried Amazon? :P search for "telescope 2" t mount nikon" and you should find a bunch. Note that you might end up with two pieces. One is the t mount usually with M42 threads, the other is the ring that connects to the camera and t mount. Just make sure the threads are the same, if they seller can't specify that I wouldn't buy from them.
