Since Spectroscopy will be a manual operation I will have the option of choosing a guide star in an appropriate location on the guide camera (it's got an ST7 sized FOV and the motion should give me at least a couple of hours before I need to reset. I imagine then I would take a series of 'short' exposures and stack them. As a spectra, I imagine the stack would be a straight out overlay with no alignment required?
Guide star offsets - I'll have to look deeper into the manual for MaxIm.
Thanks.
