Engineered for wide-field astronomy that includes viewing the moon, picking out your favorite constellations, comet hunting, satellite spotting, or watching for iridium flares, the Barska 25x100 WP Cosmos Astronomical Binoculars Matte Blackare an ideal companion for dark and starry nights.

Outfitted with a magnification and objective lens size that rival many beginner telescopes, the Cosmos ensure a generous field of view, comfortable eye relief, and wide exit pupil for easier viewing. The traditional Porro prism light path presents a rich depth of field, while producing a naturally balanced and comfortable feel in the hand. The chassis' ergonomic feel is complemented with textured armor to further improve grip security. Both optical tubes are nitrogen filled to be waterproof and resistant to the internal fogging that can occur when moving from the inside of a warm house to the outside into cold winter or sultry humid summer nights. Weighing in at almost nine pounds, holding them by hand is impractical, so Barska made them mountable on a wide variety of tripods, quick release plates, and heads with an integrated 1/4"-20 tripod mount.

Q: 1. Are these binoculars good for sky watching, or should I get a different brand?

A: Yes these will work very good for Celestial use. You can also do the Nikon 7x50 Aculon A211 Binocular. These would be a brighter choice due to the lower magnification. Link: http://bhpho.to/1O7uUCg

Q: 2. Do you have an item that will allow me to see an object in detail from a 2-10 feet distance with clarity?

Q: 4. I have a Celestron 25x100 binocular that came with a Celestron Alt-Azimuth tripod Model 93607 but they don't seem to mate very well and the tripod does not elevate more than a few degrees above hrozontal. Do I have the wrong tripod?

A: I have the same binoculars and tripod. The mating to the tripod is very solid; no problem at all. Perhaps you've sorted that out by now. The range of elevation angles is somewhat limited from what I'd prefer. It's about plus/minus 20 degrees. However, anything more could make it very awkward to sight through the binoculars.
