When talking about wide-field binoculars, don't forget the Carson 8.5x42mm binoculars. These have a FOV of 578' @1,000 yards, corresponding to a 11° TFOV and a whopping 94.5° AFOV. Eye relief is of course very tight (certainly in the 10mm or less range), and edge sharpness, well.... it's what you would expect in a field this wide.
I have a pair of Miyauchi 5x30 Binons and the TFOV is not all that different. The main difference is that the Binons have better centre sharpness and much better eye relief. But the Carson's have the benefit of significantly higher magnification. Anyone looking for very wide field of view binoculars (and who doesn't wear glasses!) should certainly at least consider these (they usually sell for around $150).

Hi Kray,
Your impressions of the Expanse are much like mine. They ARE different.
I believe that Kenny may have gotten a bad sample.
You'll enjoy them this summer--that I'm sure of. These are great for "catching" things in the FOV that other bincolurs can not/will not accomplish. Good luck and good viewing.
Best regards,
Dave.

In this same family, Bresser is selling a superwide 10x50. It has very short eye relief. They are for sale in Europe but not in the States. It is a novelty binocular.

In regards to the Orion Expanse 7x32, there is a fairly simple way to conditionaly align them. The entire mirror-prism-mirror assembly moves as a single unit. There are two spring loaded adjustment screws for each assembly. the third point of contact is a pivot point.
I wouldn't suggest using these adjustments unless one has double vision through the binos and you've determined that repairing them is too expensive and the only other choice is to throw them out.

Well, I have discovered that reading this forum is hazardous to one's pocket book. When the chance to acquire a SARD 6X42 came along I held my breath and jumped off the cliff. I have had nothing but cloudy nights since it arrived so it has seen only daytime terrestrial use so far--but I can only say, "Shazam", I see what the excitement is about. I have never experienced such a field of view before in a binocular. I have not done any subtle analysis of what portion of the field is sharp, etc. The instant impression of looking out a picture window with magnification that one gets when these are first put to the eyes is quite impressive. Surprisingly, they seem to have enough eye relief that I don't think a lot of field is sacrificed when wearing spectacles. I hope tonight may be clear enough to try them under the night sky.
