I have an Opticron HR 80 GA ED, and it came with an SDL/2 eyepiece. I wear spectacles nearly all of the time, and I'm wondering whether a fixed eyepiece, such as the 40831, might be better. Zooming in rarely gives me much improvement. Anyone with direct experience of the 40831 and HR 80 GA ED, who can comment?
I also have an SDL eyepiece, first version, but that isn't fully compatible with the HR 80 GA ED - it no longer focuses on objects a long way off with that fitted. The eyepiece works nicely with a much older HR60 'scope.
