Celestron SkyMaster 20X80 Binocular

First thing first, delivery service, packaging was great. This is my first binoculars ever. So I can't say if this piece is completely out of collimation (will give updates once I check). Pros: 1. Well built. 2. Fully multicoated optics. 3. Value for money. 4. Best for beginners in Astronomy. Cons: 1. Quality of the bag provided is not good. (substitute would be a DSLR camera backpack and it will do the job). 2. Collimation could be a problem. (Almost all heavy binos have this error). You can fix it yourself or could ask for a replacement. In detail:- 1). You cannot get this quality at this price. Compare with ORION 20X80 --- which is around ₹ 25k. 2). If you cannot decide about getting 20X80 or other smaller binos then I would say 20X80 would be better. It has a larger objective of 80mm which increases your limiting magnitude to approx +7(with naked eyes your limiting magnitude is around +1). That's a huge difference. You will be able to see most of the messier objects and other DSOs apart from Moon, planets, and Orion nebula. 3). It is literally a pair of two small telescopes😉. A telescope equivalent to these binoculars will be above ₹ 30k (trust me), So this is a great deal. Some important points: 1). You can adjust the interpupillary distance. (As any other binoculars have) 2). You can adjust the dioptre setting (for individual focus adjustment for eyes) by rotating the right eye piece. (please Google for more information) 3). Centre focus wheel is given. ( For focusing at different distances) (All above three adjustments could be stiff in the starting) Suggestion for Tripod: 1). A fluid head tripod is a must (for smooth and precise maneuvering of binoculars). 2). Tripod must be heavy (to keep binoculars steady/ 20X magnification is too much). 3). A branded tripod is not required. 4). I will suggest getting a tripod from a photo store. (If it's in your budget then Manfrotto fluid head tripod will be the best) An Update: 1). Saturn's ring is visible. It will need a nice focus and patience. 2). The object should be at the center of the field of view to avoid chromatic abrasion. 3). Four of Jupiter's moon are visible. You can not make out the Great Red spot. 4). After watching planets for an hour, I found my binoculars are perfectly collimated. 5). Bright objects (-2 magnitude or higher) will give chromatic abrasion. 6). You will be able to see stars as dim as +8 magnitude in a light-polluted sky. 7). Andromeda galaxy will cover your entire field of view on a very dark night. 8). Many DSOs around the Sagittarius constellation are visible from these binoculars. 9). The field of view is around 2.6° and not 3.7° as mentioned. 10). The moon looks breathtakingly beautiful. It will appear three dimensional with these giant binoculars. You can make out Apollo missions' landing sites to a precision of few kilometers. 11). Orion Nebula will be visible bright and crisp. Your field of view will be contain just the Orion sword. 12). If you are willing to do astrophotography using these binoculars then you will need a smartphone adapter for binoculars (just search for it and you will find it on amazon) and a photo staking software - DeepSkyStacker which will stack together hundreds of shots of a DSO and after few hours of processing, you will get a bright and detailed astrophotograph. 13). Neptune and Uranus are visible just like a dot but you can make out their color. Best at this price!! Clear skies!!

Guys, this is a honest review. I bought it for 13500 INR combined price on 12th of july 2020 along with digitek 880 pro tripod, in conjunction they work fabulous. I have used it for a month and a half till now, since I had early experience with star charts , star gazing apps and nautical astronomy from my college, it became easier for me to do binocular astronomy with these huge ones! Trust me, I belong to Hyderabad rated class 9 on bortle scale and I have seen upto 10 dso's which obviously looked faint due to light pollution at my place. We can easily make out Jupiter and its four moons. No offense but Jupiter looks just like a bright dot. Saturn's disk can just be identified under keen focus. Sunset visuals and the moon looks breathtaking awesome! I was also able to see Neptune as a red faint dot. I have also used them for bird watching (eagles) and terrestrial spying too. These activities are always fun with them. Every experience through celestron skymaster 20by80 will widen your eyes open. It is not so big as 25by100 and also not so small, being perfect for an amateur astronomer, tripod is compulsory(as they weigh 2.1kg)! A photography tripod works best. Handle them with care and they may serve you many years and I can't wait to get to a dark night sky and visualize milky way through this binoculars. Get a mobile adapter and adjust your camera settings to capture amazing images of celestial objects. As far as I know, this is the best binocular you will get at a cheaper price of best quality. Happy stargazing and clear skies!

Received defective product, requested for refund

The binoculars arrived in good condition and they were properly collimated. These binoculars are relatively lightweight for their size; don't mistake me, they are not meant for hand-holding. They need to be mounted on a sturdy tripod. I am using it on my Gitzo tripod + Markins ball head; works good. Positives: Physically they seem to be fairly sturdy. The objective diameter is 80 mm as advertised. They seem to be multi-coated; they show a pale green reflection against light. The inside of the barrel is corrugated and properly blackened. The exit pupil is well rounded. There is no cutoff of exit pupil, nor there is any detectable vignetting/light fall off. I viewed many deep sky objects with these and thoroughly enjoyed the view. Negatives: Brighter stars not pin-points even at the center of the field, they exhibit spikes like diffraction spikes of a newtonian. But for fainter starts this is a non-issue. The rubber eye-cups are a bit hard. For my interpupillary distance the eye-cups are so close that I cannot fit my nose between the eye-cups. Hence I am not able to place my eyes close enough to get a full field of view with eye-cups up. When I fold down the eye-cups I can enjoy the full filed of view. The eye relief does not seem to be 18 mm as advertised, It seems to me closer to 12 - 14 mm. I have not measured it though. The filed of view is close to 3.2 deg, not 3.7 deg as advertised. There is colour fringing on brighter stars. I haven't had an opportunity to view moon through them. When mounted on tripod, even after the top knob is fully tightened, the binocular yaws a bit to left or right. Finally, the bag supplied is of poor quality. It does not provide much protection to the binoculars. Still, these a pair of good binoculars, capable of providing hours of joyous deep-sky views under dark skies. They are value for money.

This binocular is extremely heavy, but the tripod Other than that the moon looks stunning through this ❤️

10/10 for product quality The visual through this powerful binoculars has no comparison in 13-15k price range. Best for amateur stargazing as well as terrestrial use. The image is sharp and clear, nothing compared to the picture i have uploaded using my phone and some editing, the actual view is far better. It would have been better if it had little more zoom upto 25x but still its fine. Can see more stars than u can through unaided eyes. Tripod is mandatory as it is around 2kg, cannot hold it for much longer. I would suggest everyone willing to buy this binoculars should also buy a mobile adapter for clicking pictures if interested as it’s very hard to hold the phone steady enough to focus and click pics. Note: images above are clicked through iphone 8 without a mobile adapter. It will be your companion for long if taken care.

Everything is great about it, although huge and bulky, gives crisp images, but I had to return it as soon as I came across an ergonomic issue. The best place to look for clear skies is straight up, and while seeing through these have to extend my neck for a long time and it gives neck pain, as opposed in a Telescope this issue gets resolved as we usually see at 90 degree. One would argue that we can lie down and mount the Binocs on a Tripod, but it becomes a little cumbersome. But what I do like about it was it gives Crisp & clear images, but get a sturdy Tripod for it. Moon and it's craters seen clearly, rather very bright. Pleiades could be seen directly without a tripod. Overall a great product to have, with Crystal clear optics. Have ordered a Orion Skymaster 100mm reflector Telescope with Dobsonian table mount instead, hope I made the right choice.

Looking for a good telescope for my Son. As Astro Pro suggest to start from a Binocular instead of a telescope which is complicated to setup and focus, which easily wears off a Kid's interest. After a careful study from Astro forums, chose this particular model Celestron 20x80. Pros. 1. Good image and could focus structures up to 10 Kms. (Hot and Humid air may degrade viewing distance) 2. Quality build and good protection accessories. 3. Able to clearly get Jupiter and its Moons from light polluted area (Chennai). 4. Could see moon features clearly. 5. Greater degree of view makes focussing easier. Must need a tripod stand to avoid shaky sky/Land views. ( Bino Weighs ~ 2 Kg, cant hold steady ) Looking to explore more in a remote area with no light pollution.....
