Confused about flatteners and spacing
I have a 70mm f/6 ED scope that I'd like to try some imaging with. I understand that a flattener is pretty much essential, but don't quite understand what spacers, if any, I would need (I haven't even decided which flattener I would get).
Can anyone give me some examples of their own gear? I'd be using a Canon 30D.
Thanks
Morton
