To answer a few questions
I have a very nice 80mm APO refractor and a 10' F5 Dob. Both scopes can take 2' eyepieces but I do the bulk of my observing in the back-yard of light polluted Sydney.
I like the 26 Nagler due to exit pupil it provides but the Explore Scientific 24 82 seems to get a lot of praise and from what I gather from some of the o'seas forum the only reason we are having this wonderful sale in the first place is because Explore Scientific are really making huge in-roads into Televue's market share with supposedly equally good quality.
I understand the laws of diminishing returns and so because the Televue is double the price I don't expect it to be doubly better than the ES - but for the huge leap in price I think it reasonable to expect an immediately discernible difference - it doesn't have to be gigantic - just clearly noticeable
