My personal experience with Televue Naglers and Explore Scientific says to me the price difference is not justified, however, put the Televue name on anything and people will buy it at a premium. Equipment snobs, perhaps, but everyone should probably have one Televue EP so they are in a position to comment on comparisons. Personally the lowly GSO Superwide EPs are my favorite, extremely sharp, wide field of view, and they get used more than the more expensive peers. I recently sold off many of my expensive EPs but i have kept the GSO Superviews, and my 11mm Nagler. If you want to impress people at star parties buy a bunch of Televues, they won't disappoint visually, unless you look at your credit card statement.
