Celestron is a leading company when it comes to the manufacturing of optics, but have they lived up to their huge reputation with the Celestron Skymaster 25 x 70 Binoculars? There is only one way to find out. Let’s go!

Optical Features(4/5)

This device features a magnification of 25x, which enables you to view images from far away distances, therefore its ability to view terrestrial images as well as astronomical images. Also, with the device’s long eye relief, you can enjoy excellent viewing without needing to sacrifice comfort. And for people who don’t want to compromise on visual sharpness, the multi-coated optics of the device enhances clarity by delivering crisp and clear images.

Construction Features(4/5)

This excellent device features a protective rubber cover which allows for easier outdoors use. This is due to the fact that you won’t need to worry about knocks and drops unless the knocks are extremely intense. This is because of the rubber material used on the binocular’s cover. Besides, rubber provides you with a firm grip regardless of the weather or the situation.

Convenience Features(4/5)

All thanks to the large center focusing knob which was strategically positioned, focusing is extremely easy with this device and every user will greatly appreciate this.


As far as price is concerned, the Celestron Skymaster 25 x 70 Binoculars is one of the cheapest binoculars you can find on the market. However, that is not to say it is ineffective because its performance is actually impressive, considering its cheap cost. If you are looking for a budget-friendly binocular without compromising on important features, then this is the ideal device for you.

How does it compare?

Orion 51464 20×80 Astronomy Binoculars

Featuring larger objective lens and high-transmission BAK four prisms, it is easy to see why the Orion 51464 20×80 Astronomy Binoculars is priced higher than the Celestron Skymaster. While the Celestron Skymaster features 12mm eye relief, which is impressive, the Orion 51464 even features a more impressive eye relief of 17mm.

If you are looking for high-quality performance and great functionalities while not minding the cost, you should go for the Orion 5164. However, if you are looking for a budget-friendly option with decent functionalities, the CelestronSkyMaster25 x 70 would be ideal for you.

Celestron SkyMaster 25X100 ASTRO Binoculars

While both devices feature fully multicoated optics and have the same magnification, the 25 x 100 ASTRO Binoculars is slightly better when it comes to the objective lens. With the 100mm objective lens on the 25 X 100 Astro Binoculars, you can view images even when there is poor ambient light. However, the SkyMaster 25 x 100 ASTRO Binoculars cost a lot more than the other device from Celestron.

Celestron is a big brand and all their products are usually reliable, but if you can afford it, it would be better to go for the Celestron Skymaster 25 x 100 Astro Binoculars.

Celestron Skymaster 20×80 Binoculars

Another excellent model from Celestron is the Celestron Skymaster 20 x 80 Binoculars. While it has almost the same features as the main product in the review, it has a larger objective lens and longer eye relief and is priced higher.  However, our main product has a better magnification, which is a plus, considering it costs less.

Do you prefer better magnification to a larger objective lens or vice versa? Your answer will play a big part in your choice between these two devices.


The Celestron Skymaster 25 x 70 binocular is an excellent viewing device. While it doesn’t come with all the bells and whistles of more expensive models, nobody can deny its obvious qualities. If you are on a budget and you are looking for a high performance binocular, then the SkyMaster 25 x 70 Binocular is the way to go.
