A few days ago I posted a beginner buyer's guide on a telescope deal. I said there that for under £60, I would suggest a cheap pair of binoculars instead.

An example is the Celestron Upclose G2 10x50. The 10x magnification is probably the most you would be comfortable with holding without a tripod and the 50mm is a good aperture for astronomy. It is finally right now back to its pre-pandemic pricing, as I would not propose it at its usual £50. It has basic BK7 prisms and a true aperture that is less than the nominal 50, so can't compete with the next tier that comes down to £60-70. But at £34 it's a good deal for a beginner stargazer.

A better deal that is hard to get though is the 10x50 that Lidl stores carry now and then. You have to keep your eyes open for those. Also, their QA is a bit hit or miss and they get banged around probably in shipping, so a lot of them lose alignment. You will have to test them in store to see if the separate images from each eye merge together easily (aim at a far end of the store), or you end up feeling you are cross-eyed. If they look OK, get them. They are pretty similar to the Upclose G2, so basic quality, but are sold as low as £20.

But the best deal right now for me is the Bresser Hunter 8x40 for £25 on Amazon. I would post that deal instead, but Amazon themselves still have them at £42, it's the manufacturer that sells them at £25 and they don't have the minimum 300 reviews in the last 12 months. They do have 3192 lifetime reviews with 4.9, and they are the actual manufacturer, so you can do the math They are a bit better made than the G2 and their true apertures are pretty close, plus they are a bit easier to hold (lighter, a bit less magnification).

There are better binoculars, some Olympus, Nikons etc but they start getting into the telescope price territory so I won't go into them - plus I didn't see a great deal.

If you want to learn more about choosing binoculars for stargazing, things to look for and things to avoid (e.g. zoom binoculars, unknown brands), check out the slides I made for a presentation at my local astro club a few years ago. Note that when I mention prices, add a 30-50% inflation, as it was pre-pandemic.

    Are these not a better pair from Bresser at £29?

    No, the 16x50 are not for stargazing. They would be a better deal for daytime observing with a tripod. For stargazing, even with a tripod, they will be quite a bit darker than the 10x50 or 8x40, so most already dim objects would be even dimmer. They'd be fine for the moon of course.
    The brightness of the image for a pair of binoculars is proportional to the exit pupil, you calculate that by dividing aperture by magnification, so for the 10x50 is 50/10=5, for the 8x42 it is 5.25 which I'd say is optimal for people over 30 who can't take advantage of even larger exit pupils because their eyes don't dilate as much. The 16x50 have a 3.125mm exit pupil which is low for astronomy. It is OK for birdwatching, but you can't really hold 16x stable enough without a stand/tripod/something to hold them against.

    I have these and for the price they are incredible.
    I treated myself to a pair of Swarovski Optik for £1500 the other year and while you can tell the difference between the Olympus ones I am not sure they are worth £1450 more .

    You mention some Nikon's being better, I'm currently looking at the Nikon P3 8x42 for £129
    How would they compare to other brands/models in that sort of price bracket?
    Will mainly be for birdwatching in the garden so minimum focus is fairly important, but also some stargazing. Cheers
    ecuador's avatar
    I was referring mainly to the Aculon series as the more comparable porro prism ones. But, yeah, for birdwatching you'd be looking at the roof prism types like the Prostaff you linked to. I don't follow the birdwatching binos that much (they can be good for astronomy of course), but if you think that your budget is being stretched, I would also look at the Opticron Adventurer II at £89. You'll have to look up minimum focus since it's important for you.
    Edit: Looked it up, Opticrons focus at 16.4 ft vs Nikon @ 9.8 ft. So you lose some there. (edited)

    thank you for educating all of us on this topic and recommending the deals based on your excellent knowledge.

    Is it wishful thinking I could put these on a tripod with a phone adapter to get more focused astrophography shots on my S23 Ultra? These are the kind I can get now on a mini tripod.

    Your s23 ultra keyboard has autocorrect enabled like mine used to, that's why your images haven't been attached properly to your comment.

    Thanks for the guide. I went with the Bresser ones from the manufacturer.
    ecuador's avatar
    I should have mentioned they have free but not prime shipping, so not sure about Christmas delivery... (the Bresser ones). (edited)

    up to 47.90

    Thanks so much for this OP. I'm a complete novice & had been looking at the Celestron all day yesterday trying to figure out whether it was a decent deal or not. Ended up going for the Bresser though as it's for my wife and she has small hands. Didn't know what 10x50 etc meant!

    Its primary use will be checking out wildlife on our walks but she also loves astronomy. Can you recommend a mobile phone mount & maybe a mount? Thanks!

    I went for £25 bresser. Thank you for your info. I always wanted to buy binoculars, but there are too many options on the market and I didn't want to buy crap
  10. 2sheds's avatar
    I too have treated myself to the Bressers. Great price.

    Another informative astronomical post OP. Thanks!
  11. Sanji's avatar
    Thank you for writing this up!
  12. bbgun's avatar
    I need it by Christmas so gone with the Celestron on. Thanks for the advice!
  13. Sanchez1's avatar
    Thanks for all the info. I went with the Bresser. Treat for myself, so not bothered with delivery times
  14. Cayde6's avatar
    Does anyone know if these have that crappy rubber coating that goes sticky after a few years?
    ecuador's avatar
    They are rubberised, but I would expect them to be of a quality that lasts years and years.
  15. abzorba's avatar
    Gone for the Bresser ones as well. Delivery 27th - 30th Dec. Thanks OP.
  16. Audio_Toast's avatar
    Cheers op, very informative post. I recently went for the Olympus 8x40 S when they were £60 on amazon as a first proper pair of binoculars
    ecuador's avatar
    That's a good set at a decent enough price.
  17. kungfuyou's avatar
    Thanks for such Detailed Info. How do you find the bresser shop that is selling the binoculars discounted ? Is it on Amazon or online? are they on their own website?
    ecuador's avatar
    Just open that link it's the default seller on Amazon currently.
  18. mumbinns's avatar
    Thanks.very informative
  19. SteveMorgan's avatar
    Can I use these to look at my neighbour, or would they need to be in the moon to do so?
    Cayde6's avatar
  20. borgman's avatar
    Very detailed post thanks OP. Would this be preferred to a monocular of similar strength? Thanks
    ecuador's avatar
    They are preferred over monoculars, unless you only have one good eye.
  21. Socratesphilosophies's avatar
    Thank you for the detailed post OP.
    Would Bresser 16x50 for £29 be better for handheld astronomy than 8x42? Primarily looking at planets and the moon. Please let me know what you think.
  22. BonkGTO's avatar
    Are these only for star gazing or can they be for birds/looking at landscapes when on hikes as well? A complete novice to binoculars, only took up hiking recently so was looking to get one and the Bresser seems a good choice. (edited)
    ecuador's avatar
    They are great for terrestrial viewing too. Birdwatchers tend to prefer the roof prism types (you can tell them apart because they have straight barrels), which are more compact, and they also care about minimum focus distance, so they pay something extra for those characteristics.
    For minimum distance though, the Bresser can do 5m (the Celestron 7m) - so it's not like they are just for far away...
  23. jjmillsy's avatar
    Went for the Bresser 8x40 as well, especially since they are £25. Should replace a pair that I recently found out are not waterproof (misting on the inside). Thanks OP!
    ecuador's avatar
    I am pretty sure they are just weather resistant, so won't fog on reasonably wet conditions. Actual waterproof nitrogen-filled sets are over the £60-£70 mark.
  24. kimmy2108's avatar
    Ecuador, you seem very knowledgeable about binoculars. We are going on an Antarctica cruise and wondering which you recommend for whale/bird watching etc? Thanks in advance 
    ecuador's avatar
    Although my specialty is the night sky, I can perhaps advise on a good pair of roof prism nitrogen-filled binoculars which is the minimum you are looking at.

    Budget options are Opticron Adventurer II WP, Nikon Prostaff P3. I would go with the 8x42 versions - but try a pair (doesn't have to be the exact brand/model) at a store to see if you are comfortable with them, some people prefer smaller sets - e.g. 8x32, sacrificing some brightness/clarity for less weight/size.

    The low-mid-tier would add phase-coatinings to the roof prism, so something like the Celestron DX (or even better Celestron DX ED), or Pentax SD WP. I just looked at the Nikon at this range (Monarch M5), but it has a smaller field of view than what I expected, so I am not adding it to my list, although my list is definitely not intended to be exhaustive.

    I am not very familiar with the "high end" Zeiss, Swarovski etc, so if you have a high budget you'll have to ask a bird enthousiast, we, astronomers, spend hundreds and thousands only on telescopes

    Oh, and have a great trip! (edited)

    price gone up to £44.98... I was going to buy otherwise

    The better deal is still available though at £25.
