  • These are great on a camera tripod if you already own one, better value than most telescopes in this price range. I'd recommend purchasing a sturdier tripod mount than what is supplied though because the supplied one is a bit flimsy.

    • Was looking at the 70mm Celestron travel scope as well amazon have for my little one but reviews say Tripod is flimsy and doesn’t stay still even if screws are fully tightened which is a shame as it seems like a great price.

      • It's definitely a viable mount but there is a perceivable difference between the two. In my experience it was nowhere near as dramatic as what those reviews made out though.

        • I was looking at this too, can you mount it on a standard camera tripod because that would solve that problem?

          • @thatsapaddlin: Yeah the Celestrons typically come with a tripod attachment. The screw thread is covered by a plastic cover (it's that orange Celestron logo between the lenses, in front of the focusing dial). The mount is direct from there to a tripod screw thread, so you can screw any tripod plate into it. The main problem people have with the packaged one is that I believe the material is plastic (don't quote me on that though, I'll have to check my old one if I still have it), the screw connection to the binos has a little bit of give to it, which wouldn't seem like much but when you're looking through that level of magnification it is quite annoying

  • Is this good for looking at the moon and shit?

  • Showing $122.29 now

  • Are these powerful enough to watch across the street at…..things????

  • Price $122. What gives?

  • Great won't need my contacts to watch TV and won't have to buy a bigger tv .

  • Good for bird watching

  • I think in a previous deal a lot of commenters were mentioning how once they purchased a nitrogen sealed pair of binos they wouldn't go back to an unsealed pair. This one is unsealed?

    I really don't know much about binoculars, how does this one compare to this deal - https://www.ozbargain.com.au/node/565881

    Which has a bigger and brighter image with more zoom? Does one have more clarity than the other?

    • Good question. I purchased that earlier deal so I'm also curious to hear from someone with knowledge on the subject.

      • I just purchased these for now and can cancel anytime as these are on backorder with ~2 weeks until shipping.

        If I understand right the binos in this post have a bigger and brighter image with more clarity than the one I linked to, however they are basically useless if not on a tripod as the FOV at 1000m is 141* (like super zoomed in). They also are not rated for all weather outdoor use and have to be treated much more carefully otherwise you can get fogging or mould inside.

        I want a pair with the most zoom as I live in a CBD highrise apartment with views of markets and parks (I like to people watch, call it what you like) and have a spare tripod with a fluid head that would be great for these - but I also already own an old Canon SX50HS from a ozb deal like 7 years ago that has 1200mm zoom that I still really enjoy using for this purpose. Guess with Prime I can always return if I don't like them.

        • That's not necessarily correct as it's relative. These do have a much larger objective lens but with the higher magnification you have a much smaller exit pupil. These have an exit pupil of 2.8mm, whereas the linked ones have 4.2. The size of the exit pupil determines how much light falls on your pupil. In dim light, our pupils dilate to around 6mm but in bright light they contract to around 2.5mm. So these would not appear to be as bright in dim light.

          • @wolfshooter: Thanks for the explanation and especially the relationship between exit pupil and our own.

            For yourself how important is the actual brightness opposed to perceived brightness if comparing 2.8mm and 4.2mm exit pupil in dim light? Would you be able to see stars or make out details on a far away billboard with 4.2mm that you wouldn't be able to see with 2.8mm? Or is it more dependent on how good someone's night sight is?

            In your opinion if someone has good nightsight, would they still be pining for a 4.2mm exit pupil over a 2.8mm pupil because it's that much better?

            • @studentl0an: In relation to 4.2mm over 2.8mm, you'll always want better :) I only use telescopes for night viewing so my experience is different to binocular users. It also depends on the object you're viewing. If the billboard or space object is large and bright in your lens, it will still look good at 2.8mm - ie the moon or a lit billboard that fills the view as your pupils won't need to dilate. But stars will look much fainter because their surroundings are black.

            • @studentl0an: Also, you'll definitely see stars, just maybe not as many as with a brighter pair.

  • I remember a comment saying that 10x70 is better for viewing the sky as it allows more light.

    • Yes the magnification is the key - objective lens of 70mm divided by the mag factor of 10 gives an exit pupil of 7mm, which is as big as a dilated pupil. Translation, they would appear almost 2.5x brighter when looking at the night sky.

      • So this one is not ideal?

        • It would be excellent for daytime terrestrial views… :)

          Edit: also good for looking at the moon, as it's bright

        • Maybe not ideal for what you're after. Probably ideal for a specific application though. In my very limited "research" 6-10 / 42-70 seems to best config for general all-rounder viewing. These bino's have significantly higher magnification (25) and may require stabilisation as a result and are better for brighter (daytime) activities due to the brightness ratio mentioned previously. Don't take my word for it though - if anyone can offer corrections to this…

  • CCC says it used to be $100 till July. Probably extra demand to "watch" neigbours during lockdown spiked the price.

  • Just be aware that if you order these for astronomical use they will come with the added bonus of several days of full cloud cover as soon as they turn up. The number of rainy or cloudy nights tends to scale with purchase price too…

      Can confirm.

      I've only had 3 nights use since picking up my 15x70.

    • Can confirm. Bought a star tracker for astrophotography right before 6 months of bushfire smoke I could barely see anything through let alone photograph :)

    • So true. Bought myself a new mount (EQ6-R) and scope recently.. and it's been raining an storming here in Sydney most of the time :(

  • Are these worth getting as an all round my first binocular?

    • they are much larger then noirmal binoculars and you would need a very steady hand because of the magnification. I wouldnt reccomend them for general use.
      But if you are not moving around much with them and are on the back veranda all the time then maybe they might be quite good.

  • Bought this recently to look at the hills (and neighbours) and if looking very far away then yes you need a tripod. If a few hundred metres, well worth it. (Was able to see a plane flying around at dusk - very unsteady hands).

    Keep a note that they're heavy so probably not ideal to lug around.

    All in all, would recommend (I think I got it for ~$160)

  • Convincing myself I don't need it since I own Celestron Regal M2 100ED Spotting Scope and don't use it much.

  • Grabbed one thanks.

  • Received mine today. Thanks OP. Can anyone recommend a good tripod?
