Small really is beautiful!
I purchased this scope in June because my 52-pound 6-inch SCT seemed to be getting a little heavier every year. It arrived on the 16th of that month in a box that looked capable of surviving a fall from a second-story window. As usual, OPT's service was first-rate.

The telescope is more than first-rate. Small, light, easy to handle, with a fit and finish that any scope maker would be proud of. And the view? In a word, stellar. Yes, there is some color fringing, but only on very bright stars, and you see it only if you look for it. The view of the Moon in this scope is superbly clean and pure, with plenty of contrast and fine detail visible. Saturn shows cloud banding in its atmosphere, along with Cassini's división. Mars? Bright red, more than in my SCT, with the polar cap standing out. And DSOs? Even under massive light pollution, this little scope has shown me numerous faint fuzzies, such as M4, M27, and M57. Can't wait for the Winter sky to arrive, so I can really ler 'er rip!

Sometimes, less really is more. No better example than the Stellarvue 80 ED doublet refractor.
