BAK4 Porro Prisms XLT Fully Multi-Coated Optics Wide Angle Viewing: 66° Nitrogen-Filled, Water and Fogproof Aluminum and Polycarbonate Chassis Center Focusing with Diopter Adjustment Built-In Standard 1/4"-20 Tripod Mount Fold-Down and Winged Eyecups Detachable Rail for Finderscope Designed as an ideal optic for wide-view astronomical or long-range terrestrial observation, the Celestron 15x70 SkyMaster Pro Binocular
features their proprietary XLT multi-coating system to reduce
reflection and increase light transmission through the entire optical
system. The porro prism configuration provides a rich depth of view and
high-contrast to draw users into an immersive observational experience.
The combination of optical coatings, prism, and over-sized 70mm
objectives produce high-contrast views that are bright and crisp with
accurate color fidelity.
To help reduce weight, the binocular
housing is made from a combination of polycarbonate polymer and
aluminum. The aluminum provides strength in key areas, while the
polycarbonate is temperature-resistant to limit expansion and
contraction in extreme temperatures, which can cause the optical
components to move out collimation and preventing the ability to achieve
sharp focus. Large objectives and long optical tubes make the SkyMaster
Pro fairly heavy with a center of gravity biased forward, so
hand-holding it may cause fatigue and noticeable hand-shake. A center
stabilizer bar has a built-in 1/4"-20 tripod adapter to mount the
instrument, with a detachable rail for a red-dot finderscope. To handle a
wide range of environments, the optical tubes are nitrogen-filled and
O-ring sealed to be water and fogproof.

Decent binoculars
Sturdy and has some heft. I like the feel of the outer coating. Much
less sticky then some rubber coatings yet grips well. Bright sharp
images in daylight. Some violet fringing of brightly backlit (or
reflective) objects, like branches. For astronomy they render a nice
wide field that's sharp in the center then falls off, but is not
terrible. I did not notice the chromatic aberration at night. Over all
very pleased with them.
Too good to be true (almost)
The 15x70 Celestrons, as has been stated by a real binocular expert,
compare favorably with Fujinon's 16x70s. Hard to sallow, as one usually
does get what one pays for, but take that gentleman for his word, the
Skymaster 15x70s are plain outstanding, little or nothing to complain
about. You could buy a number of these, one for everybody likely to use
them of course, on your holiday shopping list, and not go wrong!
Wow
There are no words, when you go out and see the night sky youll
understand. I read they were heavy. I have little problem holding them
for 20 minutes, but if thats a problem they can go on a tripod. I read
it was difficult not to shake because of the high magnification and
weight. True, but you can lean on a tree or lie on the floor and it
helps a lot, or you can put them on the tripod. Ive read many recommend
10x50 instead. That depends on what you want to do and personal taste,
of course. I do have 10x50 binos but I prefer these 15x70, especially in
the winter when I cant bring out my telescope because of all the snow
and ice. Their 15x magnification is great when you dont have a
telescope. And best of all, it only takes seconds to take them out. I
can easily do it everyday and follow Venuschanging phases or Jupiters
moons move. Sometimes I just use them for 5 minutes quickly. I cant
really do that with my telescope. I can usually bring it out only once
or twice a week at home at most. These I can bring with me anywhere.
They are particularly good with large open clusters like Pleiades, the
Beehive or Hyades. Viewing these with binoculars is much better than
with a telescope. Their big aperture allows you to see fainter objects
like M81 galaxy in Ursa Major or M13 globular cluster in Hercules. These
I have seen in my light polluted neighbourhood near downtown Montreal. I
havent had the chance to go to a dark site. I would strongly recommend
any new astronomer to get some quality binoculars, perhaps even before
you get a telescope. They are much easier to use and much much easier to
know what you are looking at when you look through the lenses. Up is up
and left is actually left and you can view all of Orions belt as
opposed to only one star at a time and easily scan it surroundings
within seconds. I had no problem with shipping and they didnt have
collimation issues. Worth every dollar.
