I got a 4.8mm Nagler to use on my old 10" dob... It was good but in hindsight it doesn't get as much use as I would have liked. It needs pretty decent conditions to meet its potential. Since the dob doesn't track, I wanted the FOV of the Nagler to be combined with the high mag for lunar, planetary and double star viewing.
I wish I had of got a 7 or 8mm quality EP instead. Live and learn...
