quite dim and not necessarily naked eye visible, the amateur needs a good tracking goto mount that can point accurately at the selected target.

Boy, trying to do sciencey type stuff takes a lot of work and a lot of corrections to get useful data. This data is often very useful for professional astronomers too. In fact, I just got an email from AAVSO that passed on a request from real professional astronomers to capture data from a variable star that is apparently going through some serious type conniptions right now and the big guys are asking for amateurs to get the data. That is pretty neat, but when I looked at the details of the request, the star is of magnitude 14, which is just slightly brighter than Pluto at magnitude 15, so, no, that is way beyond my capabilities. I think you would need something like a 10-12 inch scope to be able to see that or very good tracking with longer exposures on a smaller scope.
