About this product

Model:  vixen_sg2.1x42
Part Number:  19172

The original Japanese-made ultra wide field binocular smiley

These quirky new binoculars from Vixen have been developed for widefield observation of, for example, the Milky Way.

They use a Galilean optic with 2.1x magnification which promises a more "walk in" view than 6x or 8x binoculars. 

Jointly developed with Miyauchi and manufactured to a very high quality in Saitama, Japan. 

Supplied in a soft carry case. 

Read Professor Ian Morison's Vixen SG 21.x42 review at the Astronomy Digest. 

Read Matthew Hodgson's Vixen SG 2.1x42 review at Alpha Lyrae. 

Note 1: due to the type of optic employed, these may not provide a full field of view for glasses wearers. 

Note 2: Vixen SG 21.x42 binoculars do not include rubber eyecups.

I read the official reviews which were very complementary and didnít quite quite believe them. However they were absolutely right! Very pleased.

If you use a red dot finder on your scope but struggle to see fainter stars at your location due to light pollution then you can use these to look through the red dot finder and "extra" stars are visible to complete your alignment.
They are very small and can be taken on your travels for extra dark location usage.

Being able to see Sagitta, Vulpecula, Delphinus & Brocci's cluster all in the one field of view, all perfect in miniature form as if they were being inspected under a microscope is only one reason to consider these. I am not even going to start babbling on about how good scanning the milky ways endless freckled star fields is !
Vixen knew these would make many people smile.

OK, been busy the last few days but I got a good evening outside with just these and a sun lounger over the weekend under very clear skies.

Spent a good hour or so just scanning the night skies and they really are very very good. There were no nasty internal reflections or weird flare issues. I just spent the evening scanning. It is very hard to describe, so stay with me. It is a little like having super vision as the image doesn't really feel magnified much, if at all (but is of course at x2.1), but does look much brighter and clearer than your normal vision. Just looking naked eye and with these, I suggest maybe a magnitude more, maybe two, is what you get.

So scanning Ursa Major, you get all the main stars rather than the usual seven. Once your eye is "in" you start to see things you don't see with your naked eye and which are lost through a scope/normal bins. It is also very immersive in that if you remember to just look straight ahead you don't really see the edges of the image. Just remember to move your head rather than your eyes when scanning. It is something you have to try.

Gave it a rest for a couple of hours and went and watched TV until around 1:30 a.m. waiting for the Milky Way to clear my Eastern horizon/trees. Back outside and up to the top of the garden.

Just WOW!! Cygnus area was my main focus and it is really rather lovely. But I scanned for around 3/4 hour up and down the Milky Way and was blown away by what more you can see. I would even argue you could see "more" then with say an 8x bino or a low power scope setup. Just amazing. They did say these bins were ideal for scanning the Milky Way and Vixen are not wrong. I must have seen a lot of things I've never seen through a scope.

They really are amazing. Setup time? Ten seconds. And you know what, I didn't spend all the time using them thinking "I wish I had a better EP or bigger scope". I'm not one for hyperbole, but would go so far as to say with these you have a completely different view of the night sky. Wish I had a pair when I used to do imaging, that would have complemented that well.

Bottom line? 10/10 for everything. Vixen have nailed it.
