Every SkyMaster Binocular in this range presents value with its high performance views and affordability. Observing the microscopic world has never been easier! Another benefit is that the overhang acts like a lens hood on a camera, which means that it can help prevent or reduce any image flair from the sun. This is an important consideration if you use your bins in cold conditions, like when observing the heavens on a cold winter night.

I will try and see if I can confirm this, but until then I will have to assume that they are. Our proprietary StarBright XLT optical coatings dramatically increase transmission, up to 97.4% on our Schmidt corrector lenses. Overview. Celestron has designed and engineered the larger SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions. Sadly these Celestron SkyMaster 25x70 binoculars are REALLY uncomfortable to use. Celestron SkyMaster 25x70 The 25x70 combines large and therefore light-gathering aperture in a handy and reasonably lightweight configuration. These Celestron SkyMaster's have ocular lenses that are 23mm in diameter, which is around the same size as the larger ones found on most standard bins. Here, the author scans for the moon in daylight. The 13mm of eye-relief is ok, but not great, for a binocular to have a long eye-relief, I usually suggest a distance of at least 16mm. I don't understand why Celestron made them that way. In good light, the image contrast looks good, but because the image was less bright than that of my controls, it looks as though the amount of contrast is less. Each SkyMaster model features high quality BaK-4 prisms and multi-coated optics for enhanced contrast. With such a long minimum focusing distance, it was harder than normal to look for any color fringing around the edges of objects caused by chromatic aberration as I usually find it easier to spot on nearer objects. On these this inter-pupillary distance can be adjusted from a maximum of 7.2cm, right down to 5.6cm, which is nice and close and matches some of the best full sized bins out there, which means that these should be ideal for those whose eyes are fairly close set. As expected, Mars is easily observable as a small red ball, but you can't really make out any other features than that, but am told that in better conditions you may be able to make out the basins from the red areas. The Celestron SkyMaster 25x70 binocular has "Multi-Coated" optics. Features Bak-4 prisms and multi-coated optics for enhanced contrast. General Price Range: (2/6) Low Cost Binoculars. DUE TO EXTREMELY HIGH DEMAND, WE WILL NOT BE TAKING NEW ORDERS UNTIL MONDAY, DECEMBER 14. I would say that in most cases this price level is probably about as low as you should consider going if you still want to achieve a reasonably good quality image, this is especially true with higher magnifications and so it will be interesting if Celestron have managed to not sacrifice too much quality by keeping the cost down to this level. The rainguard or the eyepiece cover, like the objective lens covers is made from a soft rubber, but unlike those, it does not fit as well and easily comes away from the lenses. SkyMaster Pro 20x80 Binoculars Have a promo code? Just point the telescope at any three bright objects—stars, bright planets, or even the Moon—and your telescope can orient itself with the night sky. SkyMaster 18-40x80 Zoom Binoculars Additional accessories included are the tripod adapter and a convenient carrying case to keep the binoculars safe from damage. Focusing What this means is that some, but not all (usually the first and the last) of the optical surfaces have been coated with many layers of anti-reflection coatings that reduce or eliminate unwanted light reflections, which increases the transmittance or the amount of light that gets through the system and to your eyes than if they were left untreated. Celestron do not specify the dimensions of their 25x70 SkyMaster on their specification chart, but I measured their length as 25.9cm (10.2in) without lens covers and with the eyecups folded down, which is how most manufacturers advertise the length of their devices.
