Featuring high quality BAK-4 prisms, multi-coated optics for enhanced contrast, a diopter adjustment for fine focusing, and large apertures, these binoculars offer phenomenal performance. The Celestron 71018 features a 20x magnification and an objective lens diameter of 80 millimeters, giving it a 4-millimeter exit pupil. (The exit pupil size -- the diameter of the objective lens divided by the magnification -- determines the amount of light available to your eye. The larger the exit pupil, the brighter the image obtained will be. A three-millimeter exit pupil is generally sufficient for daytime use, five-millimeters is suitable for daytime and twilight, and seven-millimeters is generally necessary for maximum nighttime or astronomy use.) The Celestron 71018 also includes an integrated tripod adapter rod, a deluxe padded soft carrying case, and Celestron's No Fault Limited Lifetime Warranty.What's in the Box Celestron 71018 Binoculars and deluxe padded soft carrying case Product Description Celestron has designed and engineered the largest SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions. Our large aperture powerful binoculars ensure high performance in all weather conditions and are ideal for astronomical viewing, or terrestrial use. Due to its size and weight—including its very large objective lenses—this binocular should be mounted on a standard photographic tripod for extended periods of use. We’ve included an integrated tripod adapter rod that allows you to mount your SkyMaster binoculars on any sturdy ¼”-20 photographic tripod in seconds. Astronomers have praised the Celestron SkyMaster for decades for its high-quality BaK-4 prisms and multi-coated optics, which enhance contrast and bring out bright, sharp images—especially in low light conditions.

Even though they are heavy and you will need a tripod. But the quality and how close and clear everything looks is amazing. It does come with a carrying case. Review: Mine arrived on time and I found them to be well collimated (aligned) If you take care not to bang them around or drop them they - I read through most of the reviews here and in other online forums and here is my take on all of it. The guys in the dedicated astronomy forums are going to tell you these binoculars are junk but then they are also going to suggest that what you really need is something you might have to take a second mortgage out on your home to buy. What this product is - an $89 pair of Chinese binoculars - you should obviously be aware of and I give it four stars because you can't beat the price with a stick. Mine arrived on time and I found them to be well collimated (aligned) If you take care not to bang them around or drop them they should stay that way but it is fairly easy to do a decent conditional collimation on them if necessary, instructions on how to do that can be found online with a Google search. The advantages of these over a telescope is that they can easily be used for terrestrial viewing as well as star gazing. The disadvantages are that they are pretty big and heavy and with 20x magnification you really need to use a tripod but viewing any celestial object higher than about 30 degrees above the horizon with a tripod is going to be rather uncomfortable due to the angle. This is why telescopes have that 45 or 90 degree eyepiece..I also found that with 20x the field of view is pretty narrow to the point that you almost need a spotting scope to get these things aimed at what you want to see. When looking at the moon for instance you are going to physically see it moving across the field of view like the second hand of a clock. For this reason I ordered a heavy duty Celestron alt/azim tripod with slow motion controls because a light weight aluminum camera tripod is not quite up to the task of supporting these monsters. Funny but the tripod cost ten bucks more than the binoculars. So far I have used these to see amazing details on a rising late night half Moon, the moons around Jupiter, the Orion Nebula, Seven Sisters and a few other things. This was from my back yard with quite a bit of light pollution so I wasn't able to find Andromeda galaxy but I'm sure in a dark space I'll be able to get a stunning view. They are also good for terrestrial viewing and especially at night, they bring in a lot of light but you can't focus on anything closer than maybe 100 yards or so. So if you think you're maybe interested in astronomy I'd recommend these binoculars. I can understand Celestron's philosophy in offering such an inexpensive product, kind of like a gateway drug. You'll certainly want to upgrade in the future but it's better than spending $500 on a telescope and then discovering that meh, you're not really into it and it just sits in the corner taking up space in the spare bedroom next to the jogging machine with all the dirty laundry hanging on it. ## Features - POWERFUL 20X MAGNIFICATION: Giant astronomy binoculars with massive 80mm objective lenses and 20x power. Pair them with any tripod for long-distance land-based viewing or astronomical observation. - WORKS WITH YOUR TRIPOD: Due to their size & weight, most users mount SkyMaster binoculars on a traditional photo tripod (not included). The built-in ¼”-20 adapter attaches to most tripods in seconds. - BRIGHT, SHARP VIEWS WITH BaK-4 PRISMS: The SkyMaster is a favorite among those who view in dim conditions near dawn and dusk or at night for astronomy. BaK-4 prisms maximize light throughput to your eye so you see brighter, more detailed images. - DURABLE AND WATER-RESISTANT: A rubber-armored housing protects your binoculars from damage and provides a secure gripping surface. The water-resistant exterior stands up to tough conditions and unexpected rainy weather. - UNBEATABLE WARRANTY & CUSTOMER SUPPORT: Buy with confidence from Celestron, a leading optics brand in California since 1960. Your purchase includes a Celestron Limited Lifetime US Warranty & US-based expert tech support. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007UQNTU | | Age Range (Description) | Adult | | Age Range Description | Adult | | Apparent Angle of View | 3.7 Degrees | | Best Sellers Rank | #224 in Camera & Photo Products ( See Top 100 in Camera & Photo Products ) #115 in Binoculars | | Brand | Celestron | | Built-In Media | Carrying case, Instruction manual, Lens cloth, Neck strap, Objective lens caps, Rainguard | | Coating | Multi-Coated | | Color | Black | | Compatible Devices | Tripod, Camera, Smartphone Adapter | | Customer Reviews | 4.4 out of 5 stars 3,533 Reviews | | EU Spare Part Availability Duration | 10 Years | | Enclosure Material | Rubber | | Exit-Pupil Diameter | 4 Millimeters | | Eye Relief | 18 Millimeters | | Features | Water Resistant | | Focus Description | Manual Focus | | Focus Type | Center Focus | | Global Trade Identification Number | 00050234710183 | | Item Dimensions L x W | 9"L x 4.7"W | | Item Dimensions L x W x H | 9"L x 4.7"W x 12.8"H | | Item Weight | 4.8 Pounds | | Low Light Technology | Yes | | Magnification Maximum | 20 x | | Manufacturer | Celestron | | Manufacturer Part Number | 71018-CGL | | Model Name | SkyMaster 20x80mm Porro Binoculars | | Model Number | 71018 | | Mount Type | Tripod Mount | | Objective Lens Diameter | 80 Millimeters | | Prism Type | Porro Prism | | Size Map | Giant | | Special Feature | Water Resistant | | Specific Uses | Astronomical viewing or terrestrial (land) use - especially over long distances. | | Specific Uses For Product | Astronomical viewing or terrestrial (land) use - especially over long distances. | | UPC | 050234710183 | | Warranty Description | Limited Lifetime Warranty | | Water Resistance Level | Water Resistant | | Zoom Ratio | 20 multiplier_x | ## Product Details - **Age Range (Description):** Adult - **Brand:** Celestron - **Magnification Maximum:** 20 x - **Objective Lens Diameter:** 80 Millimeters - **Special Feature:** Water Resistant ## Images ![Celestron SkyMaster 20x80 Binoculars – High-Power Binoculars for Astronomy and Long-Range Terrestrial Viewing – Large Aperture with BaK-4 Prisms – Includes Tripod Adapter & Carrying Case - Image 1](https://m.media-amazon.com/images/I/61aCHqOA-EL.jpg) ![Celestron SkyMaster 20x80 Binoculars – High-Power Binoculars for Astronomy and Long-Range Terrestrial Viewing – Large Aperture with BaK-4 Prisms – Includes Tripod Adapter & Carrying Case - Image 2](https://m.media-amazon.com/images/I/614VIpF9WiL.jpg) ![Celestron SkyMaster 20x80 Binoculars – High-Power Binoculars for Astronomy and Long-Range Terrestrial Viewing – Large Aperture with BaK-4 Prisms – Includes Tripod Adapter & Carrying Case - Image 3](https://m.media-amazon.com/images/I/616kA2t9b0L.jpg) ![Celestron SkyMaster 20x80 Binoculars – High-Power Binoculars for Astronomy and Long-Range Terrestrial Viewing – Large Aperture with BaK-4 Prisms – Includes Tripod Adapter & Carrying Case - Image 4](https://m.media-amazon.com/images/I/513n6jPhLbL.jpg) ![Celestron SkyMaster 20x80 Binoculars – High-Power Binoculars for Astronomy and Long-Range Terrestrial Viewing – Large Aperture with BaK-4 Prisms – Includes Tripod Adapter & Carrying Case - Image 5](https://m.media-amazon.com/images/I/713c+b8N7hL.jpg) ## Questions & Answers **Q: I am trying to decide between this model and the Celestron 25-125x80 which i would use at only the lower magnifications. Which should I get?** A: Hello! In my 50+ years as a user of hundreds of types of lenses, telescopes and binoculars I have found any "ZOOM" product is far less sharp than a fixed millimeter group of lenses. I currently purchased the Celestron 25 X 100 astronomy binoculars and could not be more pleased. Images are all very sharp with excellent contrast - both of which are extremely important when looking at the night sky as well as in terrestrial viewing. I would definitely recommend the 25 X 100 binocs. Hope this helped. Terry D **Q: Would I be able to see the rings of Saturn with the binocs?** A: Just got these in yesterday from another retailer and yes if your steady enough or use tripod you can see saturn's rings. You can see the brightest of jupiters 4 moons as star points too. I also got great views of the Orion Nebula (M42) which was amazing. All objects mention above where seen from the city. **Q: With this pair not having focus or zoom lever, would the 25-125x80 be a better pair for astronomy searching?** A: I own the zoom model 25-125×80, and now I wish I had 25 x 100. Please DONT BE FOOL BY THE ZOOM FUNCTIONILITY. 25 x 100 will definitely give you crisp image because its prime lens. My zoom bino has some soft-image problem at the edges and it seems to be very common issue. Zoom is just useless. 100 aperture will give you more light and 25x is enough to see planets and stars. Again, having individual focus ring is better that you wont get in 25-125x80 model. **Q: Are these suitable for bird watching? Specificaly birds of prey?** A: No, not at all they are like hand holding a celestial telescope. If rested on a car roof they might work, but they are annoyingly large for transport. They require a tripod and good for the viewing of a fixed object like a pack of wolves at Yellowstone 1 mile out. This much power and the binocular view is just too bouncy. The best bird watchers / NASCAR watching for the money I purchased were the Vortex diamondback 8X42. Waterproof and very clear glass, great in low light and not terribly expensive compared to the competition in this performance range. Don't get me wrong as they are a nice addition for sky watching the moon, rings on Saturn...., but practical for bird watching no. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great binoculars *by E***Z on May 23, 2026* Love this binoculars.

I wanted these as an alternative to hauling my heavy classic Celestron C-8 up into the hills over dirt roads (with washboards, ruts, all that fun stuff). These give me a lightweight alternative and work great with my heavier camera tripod. The package arrived from the UK a couple days early, which was awesome. The box looked like a cross between being re-used and having had some heavy-handed handling during transit. That was concerning, but the box inside that was in pristine condition and the actual Celestron box inside that was pristine as well. The binoculars came encased in a soft foam housing and my greatest fear, them getting knocked out of collimation during shipping, didn't happen. There were no collimation errors at all. I tested them in my in-city driveway over a few nights when we finally had clear skies. As others say, you can hand hold these, but you're going to quickly be reaching for your tripod to hold them. The strain on your arms builds up fast. Looking through them, the moon is fantastic and M31 is an impressive size. Saturn was basically a slightly larger dot than a star, and I could not make out any rings. That was expected, and I might be able to see a distortion caused to the dot by the rings at a dark sky site. Tsuchinshan-ATLAS was a joy to view. All these views were nice and clear, once the binoculars were properly adjusted to my eyes and mounted on my tripod. The only downside I've encountered so far is that when they're on the tripod, anything near zenith is hard on the neck. My tripod gets the binoculars up to a comfortable height for an evening of viewing, but the steep angle for high overhead views gives one a crick in the neck. A set of 45 degree adapters for the eyepieces should take care of that, though. I'm really looking forward to seeing the Orion nebula, the Pleiades, and other DSOs as the year goes on. I realize these won't give me "as good a view" as my C8, obviously, but what I've seen so far tells me I made the right choice for what I wanted them for: a "lightweight" alternative to lugging my heavy C8 up in the hills. This way I can always have them there whenever I go out for astrophotography. Oh, and they're pretty decent for terrestrial observations, too. ## Frequently Bought Together - Celestron 71018 SkyMaster 20x80mm Porro Prism Binoculars with Multi-Coated Lens, BaK-4 Prism Glass and Carry Case, Black - Celestron 93524 Roof and Porro Binocular Tripod Adapter, Black - Celestron – Smartphone Photography Adapter for Telescope – Digiscoping Smartphone Adapter – Capture Photos and Video Through Your Telescope or Spotting Scope Eyepiece --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/1154674-celestron-skymaster-20x80-binoculars-high-power-binoculars-for-astronomy-long](https://www.desertcart.ec/products/1154674-celestron-skymaster-20x80-binoculars-high-power-binoculars-for-astronomy-long) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-06-06*
