Celestron Skymaster 20 x 80 Binoculars - A Review


Recommended Posts

Hi all,

Been a while since I have been on the site – work has been really busy these last 18 months, and although it’s still manic, things are slowing down a bit!!

Viewing my previous posts, you will see that I was in the market for a new scope to adorn my EQ3-2 mount that I had purchased ages ago now!! Well, things didn’t turn out as expected, and while I am still hoping to get a scope, hopefully at Christmas if Santa is kind to me (I have been a good boy lol!!) I decided to get a pair of Binoculars to fill the gap!

Budget was tight, and I did want a pair of larger aperture bins. A lot of reading up on the internet, and I settled on the Celestron Skymaster 20x80’s. I already have a pair of 10x50’s so was after something with a bit more power, and larger objective’s. The skymasters seemed to fit the bill, and the price was right as well! I dropped into Rother Valley Optics with my cash on the off chance they would have a pair in stock – they didn’t, so I left my details, and less than 24 hours later, Adam from the shop called me to say they had a pair in! I drove over to their shop, tried them out outside the shop, as I had read that some pairs are known to have collimation issues. These where perfect, so I parted with my £99 cash and went home with them! First class service from RVO, and I will be using them again when it comes to getting my scope – thanks guys!

So, onto the bin’s. They came double boxed up, and within the branded box inside the plain box, the bin’s were securely packed in foam and wrapped in plastic. They come with a basic carry case, which won’t protect them from hard knocks, but will keep the dust off them while not in use. The eye pieces are protected by a one piece cover, while each large objective is covered by its own, separate cover. There is also a basic neck strap, but it appears quite flimsy, and I won’t be using it.

The bins have a built in tripod adaptor, on an adjustable slider, meaning they can be securely attached to a tripod and balanced up. Weight wise, they tip the scales at just over 2.6kg. This isn’t hugely heavy, and while I did use a tripod for some observing, when I wanted to look at things nearer the zenith, I hand held them, and did so for quite some time. I didn’t feel they were overly heavy, even after prolonged use.

It seems that new scope curse also affects owners of new binoculars, as I had to wait 5 days for clear skies!! I went out at about 10:30pm into the back garden, and while the side of house has a street lamp directly over the hedge, round the back its cut off, and quite dark. I began by finding M31, which at is currently nearly at the Zenith. I could see the central core clearly, and with some averted vision, make out some finer details in the disk. Moving on to M45, the Pleiades, that was just rising over my neighbours fence – what a sight!! Even though it was quite low down, the cluster filled the view, and I could see loads of fainter stars within it. Moving through the Milkyway, the view was filled with thousands of stars and star clusters!! I was really impressed. I intend to go to a dark sky site up in the Peak District, just north of Ashbourne when time and the weather permit, to get some proper dark sky viewing in!

I have not yet been able to look at the Moon or any planets through them – the Moon hadn’t risen by the time I turned in, and is now a very small waning crescent. I will have to wait a bit longer, and will update the review once done. Mars was up, but low in the sky, and due to the street lights, swamped with LP.

With terrestrial viewing, they provide bright and crisp views. While there is some CA when looking at things with bright edges, general viewing wasn’t affected in any way. I plan to take them to my local nature reserve to test them out on some wild life as well. I am also a bit of a plane fan, and when time permits I park up near East Midlands Airport to watch the aircraft coming and going – these will be great for that, set up on my tripod for easy viewing!

Conclusion – the Skymaster 20x80’s are a decent pair of binoculars. While they don’t have the build quality of more expensive ones, treated well I can see no reason why they won’t last for years. They actually come with a 5 year Celestron guarantee anyway!  For causal use when you don’t want to set up the main scope I think these fit the bill nicely, and I would recommend them to anyone.

Cheers all

Hiya. I've had a pair of these for nearly six years now, and absolutely love them. Currently they're with Celestron to be recollimated, and I can't wait to get them back!

I have the Revalation Astro 20x80's and are identical, except for the brand/name. Your report and descriptions are spot on with mine. The 'Coathanger' asterism just fits... and the 'Pleiades' is another one of those "Wow!" moments to add to the list. The only downside I find is that they do not have a focus for each eye as standard, but I suppose that would increase the purchase price for the consumer.

I find that using a joystick/pistol grip/trigger/ball head, as shown in the photo below, is very comfortable, rather than using a traditional alt-az/pan & tilt head with a tripod or monopod.

Update, and some pics:

Popped outside again late last night, after I got back from a pub installation in Bristol. Seeing was not so good - there seemed to be a very slight haze in the atmosphere that dulled things slightly. I returned to M45 - has to be my favourite at the moment! I could also just see Taurus rising over the neighbours hedge ,so took a look at Alderbaran - the orange colour was quite evident, and the loose cluster that makes up the Hyades was quite something!

Here are a few pics I snapped off today. The 'small' bins next to the Celestrons are my poor old battered Miranda 10x50's! The eyepiece shot was handheld using my mobile phone camera, so its a little OOF, but gives an idea of magnification and FoV.

Nice set up there Kev - I like the idea of a pistol type grip. I have a traditional photo tripod, so might look into getting one of these!

? ...I think you have got me confused!

Hi Merlin - I honestly don't know the answer to that. I would hope not, as they are marketed as 80mm. I would feel pretty cheated if that were the case!! 

They are actually 72-73mm. Hope this helps ask your question!

      Hello,
      I've been on these forums a couple of times for the last 2 weeks and ive found amazing advice, on telescopes, mounts and eyepiece. Besides reading countless of information on the internet about various equipments; pros and cons; and i got some queries about how to upgrade my setup.
      My original purchase was a 15x70 Celestron Binoculars last year, and boy ive seen amazing things with it, specially globular clusters, Jupiter and Saturn and the Orion's Nebula; for me these were amazing; i still use them given how easy it is to look at the sky with them and how bright and full everything looks.  A couple of months ago i got a 70x400mm Gskyer Telescope with an AZ mount (The cheap 99$ one that Amazon is displaying on all its adds for the last two months)  it came with a 25mm and a 10mm eyepieces as well as a x3 barlows (which i didnt even count as part of my scope as it is too bad quality and i havent managed a single decent view with it).

      Currently My Celestron Binoculars (x15) seem better for visualizing the sky than the 25mm eyepiece (x16) (things seem a very bit dimmer). And since the Barlow is a "no go", the 10mm (x40) eyepiece is what i really use, it has decent zoom and detailed views , it is my go to eyepiece most of the nights.
      However from reading all around, ive read that most of the stuff that come with the Telescope (aside from the scope itself) are actually really bad quality, specially no name brands without even webpage, so if i were to maximise my telescope i should update some of those items.
      -Recently i ordered a new Start diagonal to replace to default one (ive heard on Refractors its usually the weakest link next to eyepieces) as well as an economic x2 Barlow lens
      Keep in mind i recognize my 70mm cheap telescope will not suddendly become the Hubble Telescope, and that it doesnt matter how hard i push it, in the end such a low scope will be bound to hit its limit pretty fast, thats why i avoid 70$+ eyepieces and barlows for now.
      I expect to keep using this telescope for a good couple of months; at least until around August, when Jupiter and Saturn are more in the night sky, rather than morning.

      Now, im very satisfied with my current telescope; while the phone mount is garbage and the phone weight and the sound of my heartbeats pretty much shake the telescope out of position, as well as how cheap the mount is; it still gets the job done for seeing interesting stuff in the sky and i have managed to do some AP for some of the globular clusters, bunch of 1-2s images (with the wrong lens), not the best, not even good pictures; but decent overall for my equipment. I am currently interested in stargazing in general and some minor AP (as i dont have a camera, currently an Iphone 7s with the mount) Buuut im interested in borrowing a camera for the low sky photos without a telescope.
      I do most 97% of my Skywatching on my backyard, i live in a small country, there is some light pollution, but i can see the pleiades and the orion's nebula core on the naked eye most nights (so i guess its not that contaminated lol)
      Now; currently i like finding stuff by myself and show it to the other people around me who cant be bothered to find the moon in the sky, so setting up, finding and seeing stuff is part of what i like. 
      With all the above in mind..... Id like to plan ahead for my next purchases.
      First, im thinking a x3 barlow lens (to replace the original crappy one) and a 15mm lens (to have a bit better view than the 10mm, but less spread than the 25mm) in two or three months (with this id be able to check if my new eyepiece outperforms my default ones, but given the quality of the scope, i dont expect this to be noticeable).
      And Afterwards id love to get a new Scope, but im not quite sure what i want... and i would like some advice and help in choosing my next Scope upgrade.
      -I entered with and im liking the refractors; however i dont wanna spend 300-400$ on another refractor that is 20-30% better for triple the price
      -Ive heard really long focal lenght might bring some distortions; and also make the scope much bulkier, annnd most importantly i know that magnification is not everything; so a 1000mm long tube would prob bring too much magnifications for me to use properly on my backyard skies. So i think id settle for a maximum of 600-700mm.
      -Originally i was againts Newtonians in general, those inverted views scared me, i have a hard time of my own with my finderscope. Then i found out that Reflectors are the name of efficiency as they have more value per aperture than refractors; and as someone once mentioned "There is not really up and down in space, you will get used to it" annnd its true... save for references on the ground, like buildings, trees and mountains to help you locate where you are in the sky; once you are on it, you dont need right ups and downs.
      -I did see some 90mm Orion's Refractors as well as 90-102 Celestron Astromaster Refractors (these are 350-400$)
      -Im thinking a 130mm reflector is what im looking for; i think the 130mm aperture is a nice upgrade for my 70mm, and will keep me occupied for quite a long time; ive read about Orion SpaceProbe 130EQ and Celestron Astromaster 130EQ (ive also read, Power Seekers and Astromaster's are made out of pretty much garbage lol) Ive read that the main issue is the constant collimation required for them; but ive also read its something that can be learned and once you get used to it; its a pretty easy thing to do to keep getting amazing views.
      -Ive also seen people recommending  6-8'' Dobsonians; i know the deal with them; if anything i could aim for a 6'' one i found a litter under 300$ ive read they are amazing values for their aperture
      So, TL;DR: I have a 70x400mm Telescope, im new to stargazing, im really amazed and excited by what im seeing with my current scope, but would like an stable upgrade before the end of the year that will last me a year or two. I am interesteted both in regular and deep sky stargazing and astrophotography;  im not currently interested in an motorized mount; could deal with a regular Equatorial mount. But overall i am looking for  more aperture (100-150mm) to have clearer views; than focal lenght for zoom.

      Im also open to the fact that at one point i might have to get a scope for stargazing and another for AP; but would like an upgrade that could help me all around for both while i get initiated.
      ------------------------------------------------------------------
      Sorrry for the Huuuuuuuuge post, i was very excited while writing it; please let me know what you think and if there's anything else you'd want me to add to help understand my situation, thanks in advance!

      Complete newb here only 1 month in to it all.  Researching as much as I can each day and trying to learn new things every hour.  Here's my rig:
      Celestron AVX 8" SCT
      Celestron AVX Mount
      Celestron 2x Barlow
      Various Celestron additional eyepieces
      Celestron Starsense Auto Aligner
      ZWO ASI 224mc color cam
      I believe I can use the 224 cam as part of an auto guider solution and am wondering what else I would need for that, assuming I would be best servers with an off axis guider solution.
      Many thanks in advance...

      Good evening everyone
      I am looking at a SkyProdigy 6 telescope for a friend. the mount had a rattle/lose part. I partially unscrewed the casing and the plastic cylinder pictured below fell out. Anyone got any idea what it is or where is comes from. Looks plastic but can feel metal in the centre.
      Does anyone have a service manual or disassembly guide?
      Many thanks in advance
      Steve

      I'm after a cassegrain reflector but I don't know which one to buy,
      I have a celestron c5 and it worked wonders for all fields, I now want the same but twice as powerful as my final upgrade
      I am looking at a c9.5 for £1350 or a c11 for £2000, My question is an extra 2.75" focal worth it for £750 more?
      I will likely purchase one this week
