If I had an SV-1 mount with a RA drive only (it has no fitting for a dec drive) - would I miss the dec drive (which might be found on an EQ-3-2 with dual axis drives)? How much would I miss it? What does it do?
Basically it would make it easier to track while observing, but you would still have to do your slews manually. This could be acceptable for visible use on a budget.
