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.)

Review: For the price, an Excellent Binocular with expansive field of view & generous eye relief, especially for night sky viewing - Upgraded my SkyMaster 15x70 binos to the 20x80 model. This review concerns astronomical use, especially as it relates to casual observation. I just returned from two evenings with it under the dark skies of WV's Monongahela National Forest 1) Field of view offers wide angle eye candy. 3.7 degrees with the feeling of expansiveness--even at 20x. I could place Orion's belt in one view; Orion's sword in another; The entire Pleiades (M45) in one glimpse; much of Kemble's Cascade; nearly all sections of the Veil Nebula complex; The Lagoon (M8) and Trifid Nebulae in one field; Can almost place M7 with M6 in Scorpius in the same field, also the Coathanger asterism fits nicely into the field of view. 2) Spectacular views offered of M7 near the Scorpion's tail, The Swan nebula (M17), Dumbbell Nebula (M27), a billowing Orion Nebula (M42), Pleiades (M45), Andromeda Galaxy (M31) with companion galaxies...can seem to infer some stars on the outskirts of globular clusters M13 (Hercules) and M22 (Sagittarius). Veil Nebula is breathtaking under dark sky (t5he western side resembles a fuzzy fish hook). Can see North American Nebula near Deneb at top of Cygnus. I returned to several of these again and again--so rewarding were the views. I set it up a week ago for a backyard star party and the Pleiades was really impressive for viewers as was the Perseus Double Cluster and Albireo double star. The Orion nebula is also magnificent. 3) Generous Eye Relief is best utilized by folding the eyecups back 4) Used a 30 year old aluminum camera tripod that is sturdy enough to hold the 20x80 with ease. How I found it effective was to sit in a wooden kitchen table chair with the tripod legs fully extended and tripod close in with bino eye cups folded back. My tripod has a shaft that can rise about 10 inches more so I used that incrementally as viewing angle was increased--not unlike a barber's chair raising or lowering. Ample eye relief coupled with the folded back eye cups and raised tripod slant the bino was attached to meant I could view objects 45 degrees up from the horizontal. Objects near vertical I could manage limited viewing by actually leaning back with binos and tripod legs laying across me. That's how I viewed the Veil Nebula. Be mindful of the weight before trying this!! It was OK for me but may not be for you. Test that carefully. The 20x80 mount is more robust than the attachment I used with the same tripod with the 15x70's. 5) Clarity of image was NOT sharp all the way to the edge. However, for the comparatively low price of the 20x80 I really can't complain about this as I'd pay much more for that level of optics. 6) I have an 11" SCT telescope. The 20x80 is a nice, satisfying casual alternative to setting up my larger scope and I had so much fun with it one evening I never bothered to set up my SCT. 7) These binos are HEAVY so a sturdy tripod is recommended. The 20x80 is significantly heavier than my 15x70 set. I can use each hand held on their own for limited viewing by gripping the large ends with each hand. 8) The moon is not excessively bright as it tends to be telescopically so you need not be overly concerned about temporary "blindness" from viewing the moon then switching to other stellar objects. Eye recovery is but momentary. 9) Did finally view Jupiter. The line up of the moons is more as one sees telescopically rather than with traditional binocular views. Be advised that surface brightness is so great one will likely NOT be able to the bands on Jupiter. Mars and Jupiter are definitely bright discs. haven't yet had a good look at Saturn as its currently near the sun in the sky. Review: Great binoculars - Love this binoculars. 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. ## 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 | #306 in Camera & Photo Products ( See Top 100 in Camera & Photo Products ) #155 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 3,530 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 ![SkyMaster 20x80 mm Porro Binocular - Image 1](https://m.media-amazon.com/images/I/61aCHqOA-EL.jpg) ![SkyMaster 20x80 mm Porro Binocular - Image 2](https://m.media-amazon.com/images/I/614VIpF9WiL.jpg) ![SkyMaster 20x80 mm Porro Binocular - Image 3](https://m.media-amazon.com/images/I/616kA2t9b0L.jpg) ![SkyMaster 20x80 mm Porro Binocular - Image 4](https://m.media-amazon.com/images/I/513n6jPhLbL.jpg) ![SkyMaster 20x80 mm Porro Binocular - 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 ### ⭐⭐⭐⭐⭐ For the price, an Excellent Binocular with expansive field of view & generous eye relief, especially for night sky viewing *by S***R on September 30, 2014* Upgraded my SkyMaster 15x70 binos to the 20x80 model.

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. ### ⭐⭐⭐⭐ 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 *by K***T on January 2, 2016* 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. ## 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.ie/products/1154674-skymaster-20x80-mm-porro-binocular](https://www.desertcart.ie/products/1154674-skymaster-20x80-mm-porro-binocular) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-03*
