. In Sky and Telescope magazine, September 2015, there is a very positive test of this binocular.
It is considered very good for both birdwatching and astronomy.
Also tested are Tele Vue's new De Lite eyepieces, which are rated very highly, and also fit binocular viewers and binoculars that take 1.25 inch eyepieces. The 47 mm barrel diameter means that they will fit, whereas many modern wide-angle eyepieces won't.
This large binocular seems to be the one to get, although I think that some Vixen binoculars are also very good.
