Advantages

Celestron’s Skymaster Giant is a unique model that sticks out from the binocular bunch. Its dimensions are incomparable inside its price range while its magnification levels are top-notch once you factor in the said price. Build from quality materials, the optical elements are perfectly capable of providing bright, crisp high-resolution images. The Designers of this particular product have constructed the model in a manner where users can employ them even without the help of a tripod.

The combination of 70-mm objective lenses and 15X magnification calculates to a twilight factor of 32 (TF=√15 x 70 = 32). A lot for binoculars, but it also has really big lenses. It has to be in order to show sufficient bright images and allow good observation in low light and in the night sky.

Its BaK-4 Porro prism and multi-coated optics further help enhance vision, provide resolution, and contrast-rich images, but most of all increase transmission for better low-light observation.

The rubber coating included in the ensemble safeguards the unit and at the same time, provides a better grip so it won’t easily slip out of users’ hands. The model is the ideal unit for individuals who wear eyeglasses because the eyepieces feature a lengthier eye relief and it also comes with fold-down eyecups to accommodate the glasses.

The Skymaster is great fun for beginners as well as experienced users. Beginners appreciate the user-friendly elements of the model. Experienced users appreciate its strong light-gathering power that helps to scan the sky for dim objects at which it’s worth pointing a telescope. The dimensions of the model are sufficiently small but it’s still hefty enough.

The included tripod adapter allows attaching the binoculars to nearly any tripod. With a tripod attached, you will be able to gaze at the sky minus the hassles of a weighty pair of binoculars.

Focusing the instrument is easy, thanks to its large central focus knob. The subject in your view will not move easily so you can actually see it in a clearer fashion.

The device is water-resistant, an important feature to bring the instrument along during cold nights and during poor weather conditions. If you happen to encounter some technical issues with the device, you can take advantage of the limited lifetime warranty that the company has granted the model.

Disadvantages

There are not really any disadvantages, except maybe that the Skymaster Giant is on the heavy side and requires the use of a tripod (not included) to effectively use the binoculars.

Should I Buy The Celestron Skymaster

The Celestron Skymaster with its large aperture is ideal for observations of the night sky, comet hunting, and star clusters, but is also very useful for terrestrial observation of objects that are far but need to be studied in detail. A tripod is definitely recommended, be it for celestial or terrestrial observation.

The long eye relief of 18 mm in the 15×70 model allows eyeglass wearers to use the instrument. The 25×70 model with only 13mm eye relief is less suitable for people who wear glasses. It might help that the diopter range can be adjusted from -4 to +8 in both models. If you normally need visual aids, you just have to try out whether you are comfortable with the Skymaster.

Multi-coated lenses and prisms made of BaK4 glass ensure high transmission and high contrast images.

Celestron’s Skymaster comes at a very competitive price and it provides great value for your money.
