Description:There is now an updated version of the Kronos 30x90mm binocular called the Model II. We have some on order and will update this page once we have more information. We hear that this is an improvement over the original model, but have no details yet. Unfortunately the price has increased by $200 (our cost from the factory), so our price will go from $795 to $995. The design is changed somewhat, so will post a new picture as soon as we have one.

This 90mm binocular is surprisingly small and portable- just under 12" in overall length. As is typical of Russian optics, the multi-coatings give a somewhat amber hue to the daylight view- but this also provides exceptional contrast when viewing the night sky. The excellent optics, combined with the clever compact design, make this a very compelling package- especially so considering the serious amount of light grasp it offers for such a relatively low price (90mm objectives have 65% more light-gathering power than 70mm objectives). Comes with an nicely-machined alloy table-top tripod and a rugged lightweight padded case. Can also be used on any heavy-duty tripod and head (base has standard 1/4-20 and 3/8" threading).

Kronos 30x90 Mod. II
These Kronos Russian-made binoculars are actually 30 power x 90 mm. I bought them from and they arrived in good collimation. The oculars are mounted at a 45 degree angle, which makes for comfortable astro viewing. The oculars are individual focus, and provide a sharp focus, even with my near sightedness and slight astigmatism. The view is flat pretty much across the 2 degree field of view. The 15 mm eye relief is comfortable without glasses, but the eye cups don't easily fold down, so someone who needs to wear glasses to obseve might want to remove the cups. They weigh 12 lbs, so they need a sturdy tripod and especially a heavy-duty head. I use a Bogen 3226 tripd , with a Bogen 501 video head, which works nicely. You can just make out the rings of Saturn and equitorial banding on Jupiter. I especailly like looking using these to view star clusters. Despite the dimmer views of a 3mm exit pupil, the 30 power teases out a lot of detail. If you obtain a pair, two recommendations: get a red dot reflex sight to aim them, and since the objectives ar very close to the end of the instrument, use dew shields (I use the flexible dew shields from Virgo Astronomics.) A pleasure to use: highly recommended.
