2. Best astronomy binoculars – detailed reviews
1. Nikon Aculon 10×50 binoculars
If you are looking for a good pair of 10×50 binoculars for astronomy then this Nikon model is a great option.
They are made by camera manufacturer Nikon, who pride themselves in producing high-quality equipment that lasts a long time.
The 10×50 magnification will enable you to see the moon in more detail and many more stars in the night sky, however these are not specialist astronomy binoculars and you won’t be spotting planets or deep-sky objects like galaxies.
Think more of a low-cost all-rounder that you might like to have around the house and take on trips rather than a serious piece of astronomy equipment.
These Nikon binoculars have multicoated eco-glass lenses that give bright and clear images in most lighting conditions, turn-and-slide rubber eyecups to allow for comfortable viewing during long sessions, and a rubber-armored coating gives a non-slip grip, even when wet.
The smooth central focus knob makes these binoculars simple to operate and easy to focus.
The premium quality also means that when fully zoomed in the view remains crystal clear, which is something you may lose with a budget option.
There are also other good (more powerful) Nikon models available – including the 16×50 Aculon.
- 10 x magnification
- 50mm lens diameter
- 2.79 pounds weight
2. Celestron SkyMaster 25×70 binoculars
This is the first model in this list that are specialist astronomy binoculars from a known astronomy brand (Celestron – who make high-quality telescopes and other equipment).
“Giant” binoculars are defined as those that magnify the view 10 times or more and have 70-mm or larger front (objective) lenses.
Celestron’s 25×70 SkyMaster binoculars are one of the leaders in the low-price giant binocular arena.
Celestron has designed this model to meet the demands of extended astronomical or terrestrial viewing sessions and the 25×70 version is one of the most popular models in the Skymaster series.
They offer large aperture light gathering and so open up more stargazing opportunities and are relatively light but include an adapter so they can be used with a standard camera tripod.
Eye relief on these Celestron binoculars (the distance you hold your eyes away from the eyepieces to see the full field) is 18mm, which is a good distance for higher power binoculars and compatible for glasses wearers.
These are great value for the price with the only downside being that the outer 25% of the field of view can be a little blurry.
The trade-off from above model is a smaller field of view which is greater with the 15×70 binoculars when using by hand, but for astronomical you will need to use a tripod anyway.
This model has an adapter to attach to a standard camera tripod – just make sure you get one that is high enough for your height so that you don’t need to stoop too much when using.
- 25 x magnification
- 70mm lens diameter
- 3.25 pounds weight
3. Orion 20×80 binoculars
Orion are also a renowned manufacturer of astronomy equipment like Celestron.
These 20x magnification astronomy binoculars with 80mm aperture lenses are high-powered astronomy binoculars and at this power, the planets and their moons are viewable as well as star clusters and deep sky objects.
These Orion binoculars have fully multi-coated optics and BAK 4 porro prisms. Eye relief is 17mm which makes for comfortable viewing (even for glasses wearers).
They are heavy and so will need to be used with a tripod and the adapter to fit a camera tripod is in-built.
- 20 x magnification
- 80mm lens diameter
- 4.7 pounds weight
4. Celestron SkyMaster 25×100 binoculars
These are premium astronomy binoculars offering serious stargazing power. They are powerful with 100mm objective lenses and 25x magnification.
With binoculars at this level they are offering as much as top-quality telescopes and will bring galaxies and deep-sky objects into view.
They have BaK-4 prisms and multi-coated optics as well as individual eyepiece focus to ensure optimal focus position.
The body of these Celestron binoculars is water-resistant and they come in a padded carrying case for travel and safe storage.
These binoculars are really heavy at 8.75 pounds and so handheld use is not really an option.
They have a tripod adapter inbuilt – so no need to buy that separately – but you need to make sure your tripod can handle nearly 9 pounds of weight.
Their weight may mean that you need to look at getting specialist astronomy binocular tripods, like the Celestron Heavy-Duty Altazimuth Tripod.
- 25 x magnification
- 100mm lens diameter
- 8.75 pounds weight
5. Canon 12×36 binoculars with image stabilization
These Canon binoculars offer something different from the above options because of the image stabilization function.
This means that they minimize any shake and are much easier to use by hand – you just push the image stabilization button and the shaky image steadies.
This means that for casual stargazing and astronomy, they can be used without a tripod.
Compared to some of the above models, they are less powerful and less specifically-tailored towards astronomy, but they offer something different that might appeal to many in being more “grab-and-go” and also being better suited for regular sight-seeing or other uses you may have for binoculars.
- 12 x magnification
- 36mm lens diameter
- 1.96 lbs
