Hi Iceman,
Great info! thanks for that.
This is an intuitive question but if I mounted an ED80 on the Newtonian can I switch between the two i.e. When I want to image widefield could I guide with the Newtonian and image with the refractor or would I need another smaller refractor to guide the ED80?
The focal reducers look complicated and there seems there is an element of choice. I've noted some of the threads here dealing with the ED80 so I'll investigate some more.
cheers
