Celestron Skymaster 20X80 Porro Binoculars, Black

I'd argue that this pair of binoculars is one of the best for beginner stargazing (and even viewing some bright DSOs); the views are breathtaking, the build quality is impeccable, and the overall experience in using these binoculars was positive. Fortunately, I was lucky enough to get a pair with no noticeable collimation errors or any chromatic/comatic aberration, although with any pair of binoculars, especially heavy ones like the 25x100s, one may find glaring errors pretty often, and might be forced to get a replacement. Living in a bright suburban area (Bortle 6), the Andromeda & Triangulum galaxies could be made out as faint smudges, the Pleiades, Hyades, and Praesepe clusters simply explode into view with hundreds of stars being resolved, the core of the Orion Nebula could be made out (unfortunately more fainter details couldn't be made out hand-holding the binoculars), and Jupiter's moons are easily resolved. It is therefore important to mention the necessity of using a tripod. Hand holding this 4kg beast is almost impossible, and while the views might still be great, the full potential of the binoculars could only be harnessed through the use of a heavy-duty tripod (I'd recommend the Orion Paragon Plus XHD Tripod. Celestron's Heavy-Duty Altazimuth Tripod is too short to be used comfortably for conventional binocular use, and ESPECIALLY when looking towards the zenith). The integrated tripod adapter is particularly useful here, and feels much more sturdy than binoculars that use separate screw-on tripod adapters that may often suffer from defects. It definitely feels very strong and heavy-duty. Aside from astronomical viewing, this pair of binoculars particularly excels in terrestrial viewing. Watching the new year fireworks through this bad boy was a sight to behold. If focused correctly (which might be tedious due to the binoculars using an individual focusing mechanism, rather than centre focusing), individual firework particles could be made out from others among thousands. The resolution is noticeably better than other binoculars with smaller apertures (having tried a pair of 15x70s prior to purchasing this), and also performs well in high-distance bird watching (of course, using a tripod). The protective case is a different story. The padding inside is quite difficult to handle, and I find myself leaving the binoculars outside of their case, as it's too much of a hassle to get the binoculars in and out of the padded case. The lens covers (especially on the objectives) easily come off when pulling the binoculars out of the case, which could be a minor nuisance. All in all, this is an amazing choice for anyone who wants to get into astronomy, as they can appreciate the amazing sights of space as well as develop skills such as star-hopping and picking out fainter details. Always purchase a heavy-duty tripod with these if you want the best performance from these. Clear Skies.

I bought it during the 11/11 sale for around for half the price, it was out of collimation and out of alignment, because of the collimation views were very poor and blurry, I could have fixed it but since I could get a replacement I returned it and got a replacement, out of the box it was well aligned and collimated , many of the bulk manufactured items have Quality control issues, so you have to play this gamble and a word of advice, only one time replacement is allowed the second time you return it they refund the money

First of all you need a strong tripod (more than 6 kilos) since it is too heavy, now, we go to the functions: you can see the moon very clearly and some constellations, and distinguish planets, in addition I could see the moons of Jupiter, I recommend them

Not as expected

Need to be used with a tripod, it's super heavy and powerful. Everything is visible from our penthouse! For hand usage recommend Nikon 25x50. Suitable for travel.

The strongest binoculars I ever tried.. Main problem is weight, impossible to hold by hands for more than 20-30 seconds.. also will require strong original tripods as they're heavy to be stable on normal ones..

Me encanta Celestron! Cómo podrán ver, tengo algunos artículos 25*100, 25*70 y 20*80 La referencia a este comentario es en base a los binoculares 25*100 es un artículo ya profesional no es para principiantes es muy pesado para maniobra por lo que se necesita de un buen tripié Tiene mucho más profundidad que los otros binoculares que tengo, y mucha más definición... El precio estaba bastante accesible y la compra a meses sin intereses fue lo que terminó a animarme Los recomiendo mucho si les gusta la astronomia

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.

Son los mejores binoculares que he tenido , para observaciones astronómicas son una maravilla, respecto al envío todo muy bien buena protección

Excellent. You can see many stars and constellations.

I thought that the magnification is really good
