thanks paul,
so using a canon 350d at prime focus (fl = 50mm???) that is 25x in my scope, i would need to have a 2nd scope with the old toucam in prime focus (6mm) that gives me at least 75x or greater.
it is slowly sinking in!
i am still in the mode that my 10" dob has to always have the biggest magnification and anything else attached must automatically be smaller.
so on really small planetary nebs, you really need a decent sized guide scope???
