The answer is yes.
A DV with the slit removed ( the star image becomes the effective slit) mounted rigidly behind an eyepiece and then the camera with its lens focus on infinity, mounted rigidly behind will get you there.
GOTO sold a star spectroscope in the early 60's which screwed onto the end of their eyepieces.
You'll have fun and see the spectrum of the brighter stars.
IMHO it would be easier to save up for a grating.
Sorry for the late reply here Merlin, but just re-visiting the above, does this mean that the visible spectrum will be too faint for visual analysing, thus the need for a camera?
