Quote:Bill, I'd get the best deal you can on a CG-5 now instead of waiting on a larger mount ... the experience you'll get from actual use will be very valuable.I would also not use that 120mm scope as a guide scope ... it's simply too much dead weight that's not doing anything for you. For a nice lightweight and inexpensive autoguider get a used 50mm finder and adapt it for use with one of your DSIs (lots of threads here on CN about how to do that). That in combination with that nice 80mm APO on a CG-5 will work very well.
