Equipped with a large aperture and a broad zoom range, the Celestron 15-35x70 SkyMaster Zoom Binoculars are an ideal choice for long-duration astronomical or long-distance terrestrial use. The large objectives ensure volumes of light are gathered to see better than smaller-aperture models, and the easy zoom lever allows you set the binoculars on low-power to easily find your subject, then zoom in to detailed, close observations. These binoculars are engineered with an exceptionally long eye relief to make them comfortable to look through for extended periods of time, while limiting eye strain. Because of the size and weight of the SkyMaster binoculars, Celestron includes a tripod adapter to provide a hands-free option and relieve arm-strain, reduce fatigue, and limit vibrations.

Related Questions and Answers

Q: 1. i want binoculars to see the evening sky. what do the numbers 25x70, 20x80, 25x100, etc, describe? thanks

A: The first number is the magnification factor. The higher the number, the lower the field of view. The lower the number, the wider the field of view. The second number is the diameter of the lens. The bigger the number, the more light is let in. The minimum recommended size for night sky watching is 10x50. If the target object is faint, then 15x70 or higher binoculars are nice to have.

Q: 2. Do the oculars have threads so you can screw on filters?

A: No, this would not have threads so you can screw on filters.

Q: 3. 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.

Q: 4. Does this come with tripod adapter?

A: Yes, the Celestron 15-35x70 SkyMaster Zoom Binoculars BH #CE1535X70SM • MFR #71013 come with a tripod adapter.

Q: 5. Do you have solar filters available for the 25 x 100 binocular

A: 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

Q: 7. Will the size of the objective lens make this too bright for nature and daytime viewing?

A: When viewing with the Celestron 15-35x70 SkyMaster Zoom Binoculars, the size of the Objective lens (70mm), will allow the viewer to see more details in all kinds of lighting during the day. If one is viewing in a bright situation the large objective wikll allow the viewer to see deatils that were not viewable before.

Q: 8. I bought one of these very heavy binos. Used it a couple or 3 times on my Manfrotto t-pod. They are so heavy that, on the 4th or 5th nite, they stripped the threads off of the socket & it hit the pavement. This knocked both tubes out of alignment! At least the only external damage - to one tube - was an extremely small ding & a scratch or 2. STW - does anyone know of repair shops that do realignments? I'm in the Boston, MA area.
