I bought these binoculars at the NEAF 2 yrs ago for >$1800. The optics are IMHO "perfect" with the flattest field that I've EVER encountered for stunning astronomical images. These are the water proof series with vulcanized housing, strap and Canon case. I have added a pair of 58mm 1A UV filters that dual as lens protectors, and caps on both ends. All like new condition with original box.
While I don't believe that there is a better "as-portable" observing system available at any price at this time, my real fancy is high power planetary imaging. When the sky is right, I use my 180EDT f/9, not the binoculars, so they have really only been used a few times and need an owner who is more interested in binocular observation. M31 is truly stunning at 18X with IS (Image Stabilization) and sharp flat field! The moon is also a breathtaking sight through the these IS binocs. I'm told that they are great for birding as well!
Anyway, I see that they've come down in price (a significant loss for me), so I've cut the price > half and will sell for $800 firm.
Many thanks for considering!
