Hi Rich,
It’s fantastic you are thinking of imaging as IMHO it’s a very rewarding activity. How are your skies? If heavily light polluted, then you might be better off getting a mono a doing narrowband. If your skies are reasonably dark, then OSC should be fine. I personally very quickly moved from a small osc to mono, but I had great time imaging with the osc, even if for a short period.
Please keep us posted
