Binoculars like the Celestron SkyMaster Giant 15×70 Binoculars can take your binocular game to the next level. If you are looking for a new pair of binoculars, you might be in the same situation that I have found myself in numerous times. Maybe you have found yourself saying, “I wonder what that would look like through my binoculars?”, so you go to grab them.

Or maybe, you have become better at shooting at a longer range, and now you need equipment to match your skill. Binoculars are not just for hunters, either.

Binoculars like the Celestron SkyMaster Giant 15×70 Binoculars can be used for birdwatching, or even stargazing! Your regular run-of-the-mill binoculars probably won’t live up to the task, however, but the Celestron SkyMaster Giant Binoculars are made for these tasks! No matter what your intended use might be, you have obviously been looking to upgrade your binoculars or start out with the best that you can find. In this in-depth review, we will dig into the Celestron SkyMaster Giant 15×70 Binoculars starting with their features. Next, we will look at some pros and cons of the binoculars, what other people think of them, and some frequently asked questions. Let’s start, below, with the features:

Features of the Celestron SkyMaster Giant 15x70 Binoculars

Large Objective Lenses

With an objective lens size of 70mm in diameter, these binoculars have amazing image quality. The larger the lenses, the more light is allowed to pass into the body of the binoculars. When more available light is used, the picture is clear and bright. Allowing the most light to enter as possible will increase contrast and brightness as well as allowing for more ‘glassing time’. This is because it makes for better use in low light conditions like dawn or dusk. This is an especially good feature to have while hunting since most big game animals are on the move at dawn and/or dusk. Other lens features are also greatly enhanced with a large objective lens.  Another thing worth noting here is that large objective lenses are easier to clean. They may require more frequent cleaning due to the surface area, but it is much easier to get the cloth where it needs to be.

Lens Coatings

The lenses of the Celestron SkyMaster Giant 15×70 Binoculars are fully coated. This means that the lenses are coated from edge to edge. Lens coatings are used to keep light from reflecting off of the glass. Anti-reflective coatings ensure that the most light enters the binoculars as possible. If the binoculars are sufficient in their efficiency, a high percentage of the available light is allowed to pass through the prisms without bouncing off. This leads to better contrast, a brighter image, crisp edges, and high color fidelity. This is also a factor when it comes to glassing time. As stated above, the more light that is allowed to pass through the lenses, the more useful the binoculars will be in low light conditions. Coated lenses are also better protected from scrapes, scratches, particles, and other damages. Having that extra layer of protection can come in handy on the trip, especially if you are traipsing through the woods.

Diopter Adjustment

Having a diopter adjustment is a real game-changer. A diopter adjustment will allow you to set your binoculars in such a way that compensates for the vision differences between your eyes. Once you set the diopter adjustment to match your eyes’ focus, that adjustment knob can remain unmoved. You can focus with the regular focus adjustment knob from then on. Having a diopter adjustment will save time as well as provide an immaculate focusing ability.

Tripod Adapter and Case

The ability to attach your binoculars to a tripod is critical, yet often overlooked. When you are using optical viewing devices like these that have powerful magnification abilities, you will need to be able to stabilize. This is because, at high magnification, any slight movement will be exacerbated in the view through the binoculars. This results in a ‘shaky’ effect that is very difficult to see amidst. The Celestron SkyMaster Binoculars come with an adapter that makes it quick and easy to mount them to a tripod of your choice. Another overlooked necessity is a carrying case for your binoculars. You must be able to pack and carry your binoculars without the worry of knocking them around or scraping them. The Celestron SkyMaster Binoculars come with a carrying case to keep them safe.

Magnification and Field of View

The Magnification power of the Celestron SkyMaster binoculars is substantial. With a magnification of 15x and the capability of operating in low light conditions, it is even possible to use these binoculars for astronomical purposes. The magnification power also makes these binoculars a good hunting companion. The ability to magnify the image up to 15 times the actual size means that they are great to use for long-range applications such as spotting deer from the tree stand at long distances. The field of view at 1000yds is 231ft. This will prevent you from missing important details in your view. Many applications require the visual context clues surrounding your desired target. With a wide field of view, you will not miss them.

BaK4 Prisms

Most optics us BaK7 Prism glass. BaK4 prism glass, however, is of a higher density and better quality. High-density glass greatly reduces dispersion. This means that bright areas in the image (white light) will not disperse (break apart into separate wavelengths to create a ‘rainbow effect’) while passing through the lenses. High-density glass also absorbs more light and does not reflect light away from the viewer.

Water-Resistant

Although not waterproof, the Celestron SkyMaster Giant 15×70 Binoculars are water-resistant. This is important because the outdoors are unpredictable and demanding when it comes to weather conditions. If water does enter the binoculars, you will be faced with a permanent problem of continuous, internal, fogging. The binoculars must be kept safe from water. The fact that they are water-resistant means that light rain, snow, or sweaty palms will not pose a problem while using the Celestron SkyMaster Binoculars.

Eye Comfort

If you are planning on using your binoculars for long periods at a time, you are going to want to make sure that they are comfortable for your eyes. If they are not, you will quickly find your eyes fatigued. The Celestron SkyMaster Binoculars have soft, folding eyecups to give your eyes comfortable places to rest while peering through the binoculars. The eye relief is 18mm. This means that your eyeballs should rest at a distance of 18mm from the first lenses for optimum viewing. This is ample room for the prevention of eye fatigue.

Frequently Asked Questions About Binoculars

Q: Is contrast all that important?

A: Yes. Imagine a bright blue sky with clouds of the same color blue. You could still technically see them, but they would most likely not be noticed because of the lack of contrast between the two. It is also worth noting that high color fidelity (vivid colors) not only helps to improve contrast and visibility but is beautiful to look at as well.

Q: I don’t have a tripod. Can I use the Celestron SkyMaster binoculars without one?

A: Of course! It is just recommended that you use a tripod if you plan to be looking through them for long periods or if you need to use the full magnification power. If you have a steady hand, go for it! It is also nice to give your arms a break every now and then, though.

Q: What is so special about a diopter adjustment option?

A: It is common for people to have one eye that has better vision than the other or other slight differences from one eye to the other. A diopter adjustment allows the user to ‘offset’ the eyepieces so that they focus slightly different from one another, just as your eyes do. This will let the viewer see an image that is as crisp and clear as possible. Sure, you can generalize and ‘get pretty close’ with binoculars that don’t have a diopter adjustment, but you might be surprised at how big of a difference that one can make.

Q: Do people actually use binoculars to look at the stars?

A: Yes. What makes looking at the stars through binoculars appealing is the convenience of binoculars. A telescope is equipped to be much more effective than binoculars, but if your binoculars are good enough, looking at the moon or watching for shooting stars can be a lot of fun with binoculars. They are way more mobile and do not require the setup that a telescope does, but if you are super serious about stargazing, go ahead and foot the bill for a nice telescope.

Conclusion

The Celestron SkyMaster Giant 15×70 Binoculars are great binoculars. The magnification is excellent for hunting, birdwatching, and even stargazing. The fact that they have a diopter adjustment feature is refreshing. If you have astigmatisms like many, you will find that they are easy to focus and provide excellent clarity. Even if you do not have astigmatisms, your eyes are most likely slightly different from one another. Because of this, the diopter adjustment is an awesome feature to have. The quality of the glass and the lens coatings is also noteworthy. For the price, you cannot beat these lenses.

The Celestron SkyMaster Binoculars are designed for use at long distances and during low light situations. They deliver on both occasions, and even at the same time. If you are a hunter and looking for inexpensive binoculars to use as ‘spotters’, these are the ones for you. Sure some are fancier than these, but you will be happy with these at their price. Another thing worth mentioning is the grip. It may seem like a drivel topic, but the grip on these binoculars is great at keeping them in your hand. The rubberized texture and size of them will ensure that they won’t take any tumbles. The only negative thing about these binoculars is the fact that they are not waterproof, but with proper care and attention, that should not pose a problem since they are, after all, water-resistant. I hope that you have found this in-depth review of the Celestron SkyMaster Giant 15×70 Binoculars helpful in your hunt for the next gadget to go with your gear. Happy viewing!
