Sounds like my Vixen Fl102.... my first look at the mighty Jovian system revealed bands, spots, and coloured moons on a perfectly black background, with NIL colour fringe whatsoever (it is f/9
). Turning it to brighter DSO's revealed INCREDIBLE detail that any of my SW ED's FAILED to show, ever. I could split ANY double you can see on a spring night, easily.
It's the scope of my dreams. I know what you mean and how you feel!
