SkyMasters are economically priced large-aperture binoculars from Celestron. They're great for both astronomy and long-range terrestrial observing. The tripod adapter on the enormous 25x100 model provides support and increased rigidity. But be aware that these gargantuan lenses require an enormously strong tripod. The recommended tripod and head combinations listed as accessories here are not overkill for the application; actually, they are spot on. Slap this wonderful instrument upon an ultrabeefy tripod/head combo, and be amazed.

I waited several years to reward myself with a grand binocular experience and....I had to wait for several more months after ordering before I received an acceptable product. A few notes...I am not a novice. I have a Celstron 11 inch, a Celstron 6 inch refractor, a Meade 7" inch Maksutov, a Meade 12" Dob and a pair of Canon 8x40 binoculars, not to mention an extensive assortment of Canon Camera bodies and lenses. Not a newby and nearly 60 years of astronomical observing. The first pair arrived (a Christmas present) and we waited until Christmas Eve to open only to find that...the middle horizontal securing bolt was stuck fast. Nothing could get it to move. Sadly...we had to bag it and I called Customer Service to place a return. B&H was awesome and promptly sent me another pair. And then.... On the next opportunity I was sad to realize how poorly the columnation was. Absolutey worthless for any viewing...the doubling was horribly intense. Another call to Customer Service...a return and now (several months later from the initial order), a third pair. Let me tell you, I was pretty apprehensive. OK...the brass tacks: These are HEAVY and require a very solid tripid. Period. I have a Gitzo with a Manfrotto head and had to upgrade the head to accomodate. Even then, the binocular to tripod mount is questonable and I recommend always keeping the strap secured around the tripod to insure an accident...the binocular mount barely keeps the horizontal plane intact and often the weight of the binoculars will cause them to rotate unwanted...the binoculars shift with unwanted ease. You MUST secure the mount to tripod or you will have issues. Also, due to the extraordary weight, the set-up runs the risk of tipping over if you aren't careful. Seriously. Be warned. OK...a few nights of viewing and learning to live with the (considerable) quirks... Finally got to view and...pretty dang amazing. Really. Contrast is above average...slight Astigmatism at the edges when viewing bright (Moon and Jupiter) objects but was very happy with seeing Saturn's rings and Jupiter's beltswith really nice separation between black and white. Orion is...well...spectacular. Nothing like binocular vision on a deep sky nebula. Can't wait to observe Andromeda. Long and short? These aren't for everyone. There is no central focusing knob so each eyepiece has to be individually focused whenever viewing a change in depth. This is not very practical for bird watching. 25 power is pretty awesome but...eyepieces are not interchangeable. You are stuck with 25x. Still, the eyepieces deliver above average viewing images. Finally: Cost vs. viewing pleasure? Especially on bright nebula and the moon....can't be beat for the money. As long as you realize that quality control is sporadic and that B&H delivers awesome customer service, you will most likely be pleased. And, if you get a lemon, B&H can't be beat. They'll take care of you without hassle.

As i live on a city with light polution, these marvelous binoculars help me to see the stars, constelations and globular clusters, that's impossible without it, even the 4 Jupiter satelites. But, be aware that's need a tripod, because of the weight.

question

Do you have solar filters available for the 25 x 100 binocular
Asked by: Scott
The MrStarGuy Adjustable Objective White Light Solar Filter (86-117mm OD) might work well. However no guarantee. These really weren't made to accept Filters. You would need to purchase 2 pieces. Website link: https://bhpho.to/2iDa5RJ

question

Are the optics on this binocular glass or plastic?
Asked by: Anonymous
Great binoculars, feels like glass, but not sure. You'd be better googling it or asking the supplier sorry.

question

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?
Asked by: David C.
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.
