but it no longer works and I'm not happy after spending as much money on itOne star because it works ok but I was careful with it and transported it carefully, and after very little use and little transportation somehow the lens was out of whack. I don't understand how lens are put together in these, but it no longer works and I'm not happy after spending as much money on it. I would recommend investing in a great pair of binoculars of your favorite flavor. I had to go through this learning curve. With optics, you get what you pay for. I tried two different pairs of these...this the second pair after accidentally breaking my first pair, and I have to say that after trying a pair of Vortex Vipers that I found for a great price and I think they are better than these. I got a low end telescope I like better than these. I dont' like to give poor reviews, but I can't understand why these had so little use and were carefully taken care of and they got the lens out of alignment. If they were $25 I'd understand but they were much more than that and should have been fine under the use they had. 1Very powerful binocularIts amazingly powerful. Moon is very large & its craters are very very clear. Though its sharpness decreases at highest zoom but I liked its performance.Warning: don't try it on a cheap tripod, someone advised me to buy Ravelli APGL4 new professional 70" tripod, I bought it from Amazon and both are perfect. The binocular is heavy & should not be mounted on cheap tripods.I attached the images of Binocular, tripod, also one example for how 25X , 125X zoom look like.....The Moonshot is un-cropped image taken by a 10mp Dslr camera thru the binocular. Please ignore the focus, it was very difficult. 4Great celestial binoculars, can double for birdwatchingThese binoculars are great if you know what you're doing. The 20-100 zoom factor is little misleading. For those of you wondering, I found the maximum usable magnification to be somewhere between 60-75x in an area with just a little bit of light pollution. As a note, these binoculars are fairly heavy and impossible to keep stable enough to good viewing without the use of a tripod. The ability to fold back the cover on the eyepieces so that people with glasses have a little easier access is a really nice feature. On a clear night, you can see the rings of Saturn, Jupiter and the four Galilean moons, fuzzy patches where some galaxies and nebulae would be, and of course, the craters on the Moon. However, these binoculars are not only good for celestial viewing, I have also used them for birdwatching and found them to excel in that field as well. I wouldn't recommend these for somebody who would primarily be using them for this; however, it is certainly an added bonus for someone like me who is interested in both. 5These are better than my telescope. Awesome !!!This is my first review ever but I had to give these binoculars props... There are mixed reviews about these on amazon, some hate and some love. I was sceptical and telling myself its to good to be true to zoom in and get a telescope feel. Well you do. They are so much more fun than the regular 20x80 binoculars I had. Yes the fov is more in line with a telescope but if your buying Astro binoculars with zoom, who cares. I havnt used my telescope since I got these. The image is so more detailed being able to use both eyes. I guess its the better depth using both eyes. Im sure some might come needing calibration but there are lots of youtube videos showing how to do it. I was prepared to have to calibrate but I was lucky because they didnt need to be at all. They also have a clearer image at night than during bright sun, but my telecope was the same way. Here is my 2 tips. Fold back the eye guards for a better viewing experience and focusing. I never use them. You have to get close to the lenses. You also need a tripod. A must. Buy these if you want a telescope for both eyes, not binoculars. Hope this helps... 5Very nice binoculars for specific use. A good buy - 94 pointsMany years ago I bought my wife a Celestron C-90 spotting scope (equivalent to a straight 1000mm, f11 lens) with a aluminum Celestron case and additional eye pieces as one of her Christmas gifts (it was a lot more back then, then it is now). Since it has held up so well, and being that the Celestron brand has been around so long, I thought I would give these binoculars a try. I purchased them for $108.53 flat via Amazon Prime, versus the full retail price (MSRP) of $169.95. The general 'street price' is around $125 - $130.To start with, if you don't know optics, this set has a extremely small field of view (FoV), so be warned that they must be used with a tripod or other fix placement device. Being within the "Ultra-narrow FoV" range (denoted as 1 to 3 degrees), at 1.25 degrees this set will only have a FoV of 65.45 feet in diameter at 1,000 yards (1 degree of Arc equals 52.35987755 feet at 1,000 yards). Because the FoV is so small, and the binoculars are so long, the points of viewing interest will need to be fairly stationary or you may find it rather difficult to track. Additionally, you should also understand that these are not actually astronomical binoculars (although they could be used for that, with limited results, like examining the Moon) as true astronomical binoculars (sometimes called "binocular telescopes") will never have 'zoom', nor a central focus ring, and the 71020 in common use is generally restricted to terrestrial viewing in broad daylight. Note: If you actually want a real pair of astronomical binoculars, you would start at 25x100 (Celestron makes this) on up through 25x150 (Fujinon used to make this). The light gathering at extreme magnification will always be dampened by physics (which you can't get around, unless you make the objective lenses even bigger, and then the price will become 'astronomical'), and if you were to add 'zoom' to the mix, that would only make it worse.The objective diameter is the width in millimeters of the first lens (of which there are 2 in this case, because they are binoculars), and determines the light-gathering ability of the optical instrument by how wide they are. In this case it is 80mm, so the light gather properties of the 71020 are very good in that regard. Most modern optical instruments also use anti-reflective coatings on the lenses and interior barrels to reduce light scatter and enhance the photon quantity delivery to the eye, as is the case here. Additionally, any 'multi-coat" process is critical in its application (too thin, too thick, not evenly applied, etc) to the end result image one will see. It is in this arena that optics will tend to pass or fail when it comes to the quality of image for consumers, but you won't be able to specifically place the blame on it without lab equipment. Finally, some of the benefits of these large lenses are undone in this case due to the fact that this is a 'zoom' binocular set (which would apply to all zoom binoculars).The prism's used (to shorten the length of the instrument and correct the orientation of the image) are the industry standard "BaK-4". Genuine "BaK4" (which designates "BaritleichKron ["Barium Crown" in English] process 4, glass") prisms are better than "BAK-4", as is the cheaper, Chinese way of manufacture. The difference in slipping from what it is attempting to copy may show up as a slight 'milkiness' in the image (because it is not actually 'barium crown glass" but rather "phosphate crown glass"). When you start paying more than $400 for binoculars, then you will have a right to complain about the hucksterism, but for this level/cost, it is acceptable IF it is even actually "BAK-4". The 71020 has "BaK-4" (small "a") printed on it, but at the same time I believe the 71020 is manufactured in China, ...so, who knows? I just thought everyone should be aware.The EP (Exit Pupil) is extremely small at 3.2mm. Any optics having a EP under 4mm should effectively be used in only bright daylight conditions. 4 to 6 is average, 6 to 7 is superior, and 7 and beyond is super bright. With the 71020 having a RBI (Relative Brightness Index) of 10.24 it is rather dim (a RBI of 25 is standard). But, both of these factors are to be expected to a degree in this configuration of binoculars, especially at such a low price point.The spine (or "spar") is solid, and along with its large tripod attachment knob, will give it good stability against shake and lend confidence in grasping the pair while moving it.Surprisingly, the objective lens caps actually stay in place until removed, which is a good thing. Now if they would just repeat that on the protective eye-piece cap.The following are the actual dimensions of the 25-125 x 80 Celestron SkyMaster binoculars, Model 71020, and are given for those who might wish to buy or construct a hard storage container for this binocular instrument. The soft-sided, velcro-closing, nylon bag with nylon carrying strap that comes with it just 'seems wrong' when it comes to any type of actual protection, other than dust, so -The Celestron product box it comes in is 16 1/8" tall by 10 7/8" wide by 7" deep, which uses a 2-piece closed-foam insert to protect the binoculars.This product box also comes inside a Celestron shipping box that is 17 1/2" tall by 11 7/8" wide by 7 3/4" deep.The exact manner in which these binoculars are stowed will determine the internal dimensions required in a hard case.As this set has a integral tripod mounting system (which can twist, or have its securing knob removed), along with the fact that the binoculars can 'fold' slightly for pupilary distance adjustment, the dimensions are actually variable for storage.The EXACT dimensions are -Height A: 13.500 inches (13 1/2" or 342.900 mm) with no caps in place, and eye relief down.Height B: 13.750 inches (13 3/4" or 349.250 mm) with all caps in place.Width A: 8.5625 inches (8 9/16" or 217.487 mm) when 'folded' (dual eye protection cap does not fit properly when binoculars are 'folded')Width B: 9.125 inches (9 1/8" or 231.775 mm) when 'unfolded'.Depth A: 4.000 inches (4" or 101.600 mm) when 'folded' and the tripod retention knob is removed.Depth B: 4.4375 inches (4 7/16" or 112.7125 mm) when 'unfolded' and the tripod retention knob is removed.Depth C: 4.750 inches (4 3/4" or 120.650 mm) when 'unfolded' and the tripod retention knob is left in place.So according to my EXACT measurements -The very smallest interior dimensions of a hard case would be by using Height A, Width A, and Depth A, which amounts to:13.5 inches by 8.5625 inches by 4 inches (462.375 cubic inches) [but you can not use the dual eye protection cap].The very largest interior dimensions of a hard case would be by using Height B, Width B, and Depth C, which amounts to:13.75 inches by 9.125 inches by 4.75 inches (595.976562 cubic inches)...So it all depends on how you configure the binoculars for storage that will determine what size hard case to acquire. Personally, I'd go with the larger case, so the protection caps can be used.If you concur, you might check into the Pelican "1485 Air" case w/ foam (about $161), or the Pelican "1450 Protector" case w/ foam (about $94), but these can be expensive.You might just take the 2 very same closed-cell foam inserts that come in the box and use them inside a hinged (2" down from the most expansive face) wood or Starboard box you create for yourself with the interior dimensions of 15.5" by 10.5" by 6.5". This would obviously require time and effort.All-in-all, the low price versus quality, I regard these as a very good buy. I give it 94 points out of 100, and would recommend it for purchase, with the full understanding of what you are buying and how they can actually be used (resulting in genuine/realistic expectations). If you have boat loads of money, by all means, buy a $6,000+ professional set of top-end astronomical binoculars ...and develop ulcers over protecting them in storage, transit, use, and against theft. The 71020 is not that pair. This pair you can have fun with ...as long as you remember to bring the tripod. 5Very Happy with them once I adjusted the collimation of the 25X125X80 Celestron SkyMasterI bought a pair and the collimation was off both horizontal and vertical. I gave them a 5 star because they are easy to adjust and worked good after adjustment. Any binocular can be bumped during shipping and knocked out of whack a bit. You just have to find the adjustment screws and use a flat screwdriver from an eyeglass kit to adjust. The screws are under the rubber near the center focus knob as you are holding them as you are looking through them. You will need to carefully pry up the rubber a bit to get to them. The screws are in located in the shallow hole. There are two holes on each side. You can actually see the screws. The deeper hole who know what that is for. I did not need to poke into them. As you are looking through the binoculars have a eyeglass flat screw driver on the screw ready to turn. You will see them adjust as you are looking through them. I pressed up against my sliding door to keep it steady. I found out that the left side will adjust the vertical collation and the right side will adjust the horizontal. They do not have to be turned very much. Once figured out they adjust easy and fast. I am happy with these 25X125X80 Celestron Binoculars once adjusted. 5Unusable past 30x zoomI took a chance buying these Celestron binoculars to replace my old Tasco zoom binoculars. I had high hopes. The Celestron are amazingly light, easy to hold. The image sharpness and FOV is great at 20-30x zoom. But anything past that, the FOV shrinks to basically nothing, making them unusable. I returned them. Looks like I'll have to go with a fixed zoom. 1Needed setup but better than expected performance.I got to use these for the first time today and tonight. I have useful information for some of the complaints. First.. Setup. It is key that you follow the instructions for focusing. Zoom to the highest setting. (Heres my trick that helps with the maximum zoom problem >>Flip back the eye reliefs. Do not use them for maximum zooming<<). Close your right eye and focus the left using the focus wheel at the top center. Close your left and and focus the right eye using the Diopter Adjustment (Right lens). Open both eyes and adjust the Interpupillary Distance (IPD) (width) until you see one round scene.Today I viewed clear mountain ranges and was able to see what color cloths people were wearing on the rock opening. Some distance away and not visible to the naked eye.Tonight I saw the Rings on Saturn clear on full zoom.The Tripod is a Bushnell Advanced Tripod. Sturdy and easy to use. 5WOW!on, these things are MASSIVE!!! about 13" tall when on the table. Have not gotten to use them to really test them out, but just looking around from my home office window, they are pretty impressive. There are two radio towers about a mile from me, and full power they look like a block away. HIGHLY HIGHLY recommend that you get a heavy duty tripod and use on that for higher power viewing. At maximum power, any vibration, shaking in the hands, even a heartbeat will shake the image. I purchased mainly for when I go to the range, the 35x is perfect for anything under 1KM, so my 300M range I use will be just fine...plus not having to close one eye all the time.... 4Sucks.I had always figured Celestron to be a top brand, so I got this model. Unfortunately for me, the sheer size of it meant I waited too long to try it initially... clearly it would take a tripod so I waited to get one.Mistake. The things don't work as binoculars, the eye images don't line up. At best it's a clumsy monoculer with a parasitic twin hanging off the side. The focus isn't sharp at full zoom either.These are essentially useless, a waste of money. Unless you just like the snob appeal of walking around with something ostentatiously large, for instance as an accessory to your HumVee, avoid these like the plague.I'll NEVER buy or recommend a Celestron product again. 1

Personally, I'd go with the larger case, so the protection caps can be used.If you concur, you might check into the Pelican "1485 Air" case w/ foam (about $161), or the Pelican "1450 Protector" case w/ foam (about $94), but these can be expensive.You might just take the 2 very same closed-cell foam inserts that come in the box and use them inside a hinged (2" down from the most expansive face) wood or Starboard box you create for yourself with the interior dimensions of 15.5" by 10.5" by 6.5". This would obviously require time and effort.All-in-all, the low price versus quality, I regard these as a very good buy. I give it 94 points out of 100, and would recommend it for purchase, with the full understanding of what you are buying and how they can actually be used (resulting in genuine/realistic expectations). If you have boat loads of money, by all means, buy a $6,000+ professional set of top-end astronomical binoculars ...and develop ulcers over protecting them in storage, transit, use, and against theft. The 71020 is not that pair. This pair you can have fun with ...as long as you remember to bring the tripod. 5Very Happy with them once I adjusted the collimation of the 25X125X80 Celestron SkyMasterI bought a pair and the collimation was off both horizontal and vertical. I gave them a 5 star because they are easy to adjust and worked good after adjustment. Any binocular can be bumped during shipping and knocked out of whack a bit. You just have to find the adjustment screws and use a flat screwdriver from an eyeglass kit to adjust. The screws are under the rubber near the center focus knob as you are holding them as you are looking through them. You will need to carefully pry up the rubber a bit to get to them. The screws are in located in the shallow hole. There are two holes on each side. You can actually see the screws. The deeper hole who know what that is for. I did not need to poke into them. As you are looking through the binoculars have a eyeglass flat screw driver on the screw ready to turn. You will see them adjust as you are looking through them. I pressed up against my sliding door to keep it steady. I found out that the left side will adjust the vertical collation and the right side will adjust the horizontal. They do not have to be turned very much. Once figured out they adjust easy and fast. I am happy with these 25X125X80 Celestron Binoculars once adjusted. 5Unusable past 30x zoomI took a chance buying these Celestron binoculars to replace my old Tasco zoom binoculars. I had high hopes. The Celestron are amazingly light, easy to hold. The image sharpness and FOV is great at 20-30x zoom. But anything past that, the FOV shrinks to basically nothing, making them unusable. I returned them. Looks like I'll have to go with a fixed zoom. 1Needed setup but better than expected performance.I got to use these for the first time today and tonight. I have useful information for some of the complaints. First.. Setup. It is key that you follow the instructions for focusing. Zoom to the highest setting. (Heres my trick that helps with the maximum zoom problem >>Flip back the eye reliefs. Do not use them for maximum zooming<<). Close your right eye and focus the left using the focus wheel at the top center. Close your left and and focus the right eye using the Diopter Adjustment (Right lens). Open both eyes and adjust the Interpupillary Distance (IPD) (width) until you see one round scene.Today I viewed clear mountain ranges and was able to see what color cloths people were wearing on the rock opening. Some distance away and not visible to the naked eye.Tonight I saw the Rings on Saturn clear on full zoom.The Tripod is a Bushnell Advanced Tripod. Sturdy and easy to use. 5WOW!on, these things are MASSIVE!!! about 13" tall when on the table. Have not gotten to use them to really test them out, but just looking around from my home office window, they are pretty impressive. There are two radio towers about a mile from me, and full power they look like a block away. HIGHLY HIGHLY recommend that you get a heavy duty tripod and use on that for higher power viewing. At maximum power, any vibration, shaking in the hands, even a heartbeat will shake the image. I purchased mainly for when I go to the range, the 35x is perfect for anything under 1KM, so my 300M range I use will be just fine...plus not having to close one eye all the time.... 4Sucks.I had always figured Celestron to be a top brand, so I got this model. Unfortunately for me, the sheer size of it meant I waited too long to try it initially... clearly it would take a tripod so I waited to get one.Mistake. The things don't work as binoculars, the eye images don't line up. At best it's a clumsy monoculer with a parasitic twin hanging off the side. The focus isn't sharp at full zoom either.These are essentially useless, a waste of money. Unless you just like the snob appeal of walking around with something ostentatiously large, for instance as an accessory to your HumVee, avoid these like the plague.I'll NEVER buy or recommend a Celestron product again. 1
