EXCELLENT REVIEW. PRECISE AND TO THE POINT. 👍

Thanks for the feedback

Skymaster celestron 20x80 minha paixão.

Really thorough review for me.

Thanks for watching.

Muy buenos binoculares yo tengo unos celestron de 25 x 100 muy potentes

[@mrmaxaxl]

Very well made review. Nice colors and contrast looking through them. And sharp as well in the center. Too bad they weren't collimated correctly! Will you receive another pair? Or by some other cool binos?

[@FocusKnob]

It's permanently back to Celestron. May be if the price goes down I'll buy again. The bad collimation at the current price is unforgivable. I didn't want the trouble going back and forth at this point in time. I'll look to more affordable binoculars.

The most detailed review in KZbin! Thanks! 🤩 Subscribe and like ;)

Thanks for watching.

[@ColdWarWarriors]

You get what you pay for, I think this represents good value for money, collimation issues aside. This will give you a lot of performance. Of course if you want true high end performance in a binocular then be prepared to pay up big $$$

[@FocusKnob]

I totally agree.

[@johnstark8116]

Really appreciate your video mate, good stuff 👍 What would you think in comparison for Astro observing on going down to the 15x70 pro ED for a gain of 0.7 focal but losing x5 magnification?

[@FocusKnob]

Dropping down to 70mm in aperture robs you of about 23% light gathering capability. On the other hand the 15x70 gives an exit pupil of 4.7mm compared to 4mm on the 20x80 binoculars. If everything was equal then a bigger exit pupil may give the appearance of a brighter image if your own eyes' pupil can at least match the 4.7mm exit pupil. I've read young eyes can open up to 8mm while older people not so much. You also frame more of the sky at once with a 15X.

[@johnstark8116]

Thanks very much, I wasn't thinking that it could be as much as 23%... I'll do some research and see how much a x5 drop represents in magnification. Also what field of view is best usable in astro. It is also true I'm not getting any younger :) not saying price and weight could influence the final verdict. Appreciate your help there 👍

[@FocusKnob]

If you take an image and divided it into 20 sections. 15 sections would be what you would see with the 15x binoculars. There are two camps when it comes to binoculars and viewing the night sky. Some prefer the lower magnification as it allows you to see more of the sky at any moment. Others prefer a higher magnification to see things closer. When looking at the moon I prefer the higher magnification.

[@timclark2305]

Excellent review.. Well Done. Collimation is main problem with the bigger Celestron Binoculars

[@watdahel]

Each time I buy a binoculars I always get anxious about receiving another miscollimated binoculars

[@timclark2305]

@@watdahel I've been reviewing binoculars for the last 25 years... Always stay away from cheap large binoculars....

[@dedskin1]

Exit pupil of 4 mm is really small , if it was 6mm you would gat 2x more light , so 12x80 would be much better as far as collecting as much light as possible , or at least 15x80 , would give about 5.3 mm exit pupil , even that is double the light i think . Chromatic aberration would be less but i guess everyone can chose their own . From the specs these are Dusk , dawn binoculars , definitely not for ultra Astronomy. Or Dark . What 4.5inch telescope do you have , anyways great review , 10 out of 10 . I just didn't see collimation problem but i guess that is hard to show .

[@FocusKnob]

I have an Orion Starblast 4.5 EQ telescope. Thanks for watching.

[@Mixedpuppy]

Good review especially your analysis on the Chromatic Aberration between the two versions.

[@FocusKnob]

Thanks for the feedback.

[@DB-be9wy]

How did you come to the conclusion that they weren't collimated? I didn't see that in your video?

[@FocusKnob]

You can't exactly show a miscollimation on video. The right side view is substantially higher than the left side which made it hard to merge the views.

[@anata5127]

$450 for astronomy-grade binocular is quite cheap. Real deal astronomy binoculars start from 1K.

[@FocusKnob]

I wish I had $1K

[@shem44]

Other than Celestron SkyMaster Pro ED 20x80 , what other choices do we have that have the same specs?

[@FocusKnob]

There's the Orion GiantView ED 20x80. I've never tested it. It's less expensive, too.

[@randomescu]

i learned the hard way that a binocular too big to carry its like no binocular at all. and mine wasnt that big, only 16x50! a small, decent quality 10x25 its way better because its there. this applies to me.

[@FocusKnob]

8x25 is more than adequate for day viewing. Anything bigger in daylight your eyes will attenuate the extra light gathering of the bigger lens. Bigger lens is good when light is dim like when the sun is about to set and at night.

[@krzysztofsz3947]

What kind of tripod do you use?

[@FocusKnob]

Get a tripod that can go at least 70" tall like a Bogen 3011, 3021, 3033, 3036, 3046, etc. Depends on how tall you are. My latest tripod acquisition is a Coman KX3636 which can go to 74" tall. Checkout my review of the Celestron SkyMaster Pro ED 20x80 binoculars to see that tripod in action.

[@hakanyucel1639]

Nice and well made review! But the ruler you're holding is pretty stupidly designed Why doesn't it show "Inches" & "Centimeters" at the same time in parallel, Centimeters start from the other side!

[@FocusKnob]

I don't know what Westcott was thinking.

Как бинокль 20 крат модет быть астрономическим ? Этим биноклем разве что пропавшею овцу на пастбище искать 😂😂😂

[@FocusKnob]

Very good for sheeps

[@trident8872]

Now compare this Celestron Pro ED with Nikon monarch 5 20x56 there is huge difference

[@FocusKnob]

The Nikon costs twice as much though. It's phase coated and dielectric coated. Probably does perform a tad better. Care to let me borrow yours?

[@trident8872]

This has not real ED glass the ED glass is there in Nikon and Pentax is way different

[@FocusKnob]

There are different grades of ED glass and the best costs more.

[@trident8872]

@@FocusKnob correct!

[@trident8872]

@@FocusKnob I doubt celestrons top of the line Regal M2 ED 100 mm spotting scope is also not with real ED glass that's why one of my friends cancelled purchasing it and waiting for Pentax to launch their New Pentax PF 85 ED and 100 mm ED spotting scopes.

[@FocusKnob]

Celestron probably is using the cheapest ED glass available.

[@trident8872]

That's for sure bro!
