    2.1x42 SG Wide-Angle Binocular is rated 4.8 out of 5 by 5.
    Rated 4 out of 5 by from Vixen 2.1 x 42mm Binoculars I've been an avid collector of unusual binoculars for decades. When I heard about the latest Vixen binoculars I was destined to own a pair. The Vixen 2.1 x 42mm are a strange animal indeed. They're actually of Galilean design, but of exceptional high quality. All lenses are fully multi-coated, and easily passed the fluorescent light test. Such light show any uncoated surfaces as a white reflection. Although only 2.1 power, the field of view is enormous at 25-degrees. For instance, nearly the entire constellation of Cygnus fits in one field of view. Beware of coma at the edges when viewing stars, but the center of the field of view is very sharp and clear. Last night was the first light under a dark 6.2 magnitude sky. Wow, I saw a lot of stars, but each time I wondered if I was really seeing all that more than naked eye, only slightly magnified. M 13 was easy, but then again, I could see it naked eye as well, though not as distinctly. The rich Sagittarius region was a delight to explore. The larger clusters and nebulae were easier to see with the little Vixen's but I'm not sure I was seeing that much fainter magnitude than with my eyes alone. The 20mm exit pupils are surely larger than any human being can utilize, but that comes with the relatively large objectives and low magnification. Had Vixen increased the power the field of view would be considerably smaller. Someone younger than myself, who's pupils open a bit larger than my 4.5mm might see down fainter with these little binoculars. Despite the above mentioned, they're fun binoculars; perhaps more aptly called exotic and beautifully built field glasses. Although heavy for their small size at 2.1x the little Vixen's are easy to handhold. I hope you have as much fun with them as I have.

    Rated 5 out of 5 by from Beyond 20/20 Too early to properly comment on their light gathering properties. However, I can already say that their resolution is incredible. I have 20/20 vision, but these binoculars have joined my triplet as optics that can push clarity way passed my naked eyes. They are comfortable to use, and heavy with glass tech. They're compact and carry-able.

    Rated 5 out of 5 by from Awe-inspiring way to view the stars These low power binoculars are a great way to enjoy the stars. For me, it's a completely different experience from using normal binoculars - it's easy for me to get a stable view with these. They are easy to hold, and you quickly get used to the 2x magnification, so the sky looks a lot like it does with no optical aid, except you are seeing LOTS more stars. I wear glasses, so the field of view is about the 16 degrees specified (without glasses, it is almost two times larger, due to the use of negative focal length oculars). I was worried that the more limited field of view would keep me from really enjoying the binoculars, but I'm happy to say that I find them very satisfying to use - awe inspiring, in fact. So far I haven't been able to use them in real dark sky conditions, and I'm really looking forward to that! My estimate is that these binoculars allow me to see between one and two magnitude fainter stars, from about 4 to almost 6 in my light polluted area, and that's a lot more stars! Extended objects (such as the Andromeda Galaxy) don't show up any better for me, but I am very happy to view the stars, and am anxious to use these optics under darker sky's. I highly recommend them.

    Rated 5 out of 5 by from Unique design and high quality manufacturing Unique wide field low power binocular. With my glasses on I get at least a 15 degree clear field and without glasses much more, at least in the low to mid twenty-degrees, so the spec of 25 degrees is probably accurate. Looking at the stars at night (a tough image quality test) the image quality is very good in the center 50% and gets a little blurry progressively outside of it towards the edges. Some (but not all) of that is due to the abberations in my eye, as the exit pupil of the binoculars is larger than my pupil opening. The build quality is very high - glass and metal. The unit is small but heavy, the heaviness relecting the metal and the amount of glass. The relative heaviness (for such a small unit) combined with the low power makes for a very steady view. I use it for uqiquely wide field views of the night sky, but it is also fun to use during the day sometimes. Also, it may be good to use for concerts, musicals, plays, sporting events, etc., to get a slightly magnified view of the entire stage (or large portion of playing field), something which is not possible with other binoculars. I'll try it at the next event I go to.

    Rated 5 out of 5 by from I would buy this item again. This is a great little item for viewing the night sky. We purchased three of these for our Dark Sky Park patrons. They are fantastic for a quick view of the stars and constellations. Amazing what they will pick up and how many more stars pop into view. They are easy to carry and pass around to a group of people. Definite must for dark sky viewing.
