Scott,
Nowadays I only do spectroscopy and solar observing.
With the spectroscope fitted, the in-built "on axis guider" - a reflective slit plate is not suitable for imaging or plate solving.


I use a "generic" 60/230mm finder (similar to this: https://www.tomtop.com/p-e5765.html?...d=guscauylynew)
fitted with an old DMK51 camera which gives me 79 x 105 arcmin FOV.
I can usually place the target on the 20 micron slit gap, and if it's a difficult field, use the Astroart plate solving to nail the target.
