Except for the very few brightest this will require a spectroscope with a slit (=heavy), a mono CCD and a fairly large aperture as compared to the short refractors that populate the smaller mounts. The EQ6 is probably not on that track.

However even the smallest "high quality" mount will be much more than 2.5K so perhaps you could proceed with something needing less aperture in mind e.g. photometry, eclipsing binaries, Be stars, monitoring cataclysmic variables etc.

Being realistic, as soon as one wants to put a digital camera on a telescope (never mind the spectroscope), kiss goodbye to 5K, and then more the year after that, and after that,... ! But at least it's fun

Best,
