Browsing eBay for a pair of bins when...

[DeepThought]

I don't know about you guys but I'm sceptical a pair of £55 bins could provide a view this good:

[Beechiller]

no way my scope aint giving me a view that good!

[Pint Of Stellar]

I'd be tempted to get them to confirm that the picture is representative of what is achievable and if they were prepared to accept a refund if it is was subsequently found out to be otherwise. 

[Naemeth]

No thank you. Ruby coated lenses are a big no-no . Oh, and there is no way you're getting a view of Jupiter like that from 70mm binoculars   (unless you were on Voyager 1 when it approached Jupiter of course )

[Cath]

Some of these sellers certainly do try don't they. Unfortunately their a lot of people out there who fall for all these kinds of 'scams'

As a side question, why do they seem to colour the lens of some binoculars?

If I'm using a pair I like to see the whole visible spectrum rather than a colour tinted view. They seem to use various different colours.

That advert just SCREAMS "NO!!!" in so many ways: low-price, zoom binocular with ruby coatings (I like to call them reflection coatings, they forgot the "anti" bit). Image of Jupiter shot from Galileo probe most likely.

[DrRobin]

Bins pointing at a space picture of Jupiter pined to the wall on the other side of the room perhaps?

If it is genuine, get me a pair please, I will scrap my C11.

Oh ye of so little faith of course these views must be achievable or surely it would be considered miselling and i cant believe anyone would do such a thing. Huh next your be telling me even the large global brands misell products, scoff as if.

Cath i believe the purpose of various colour coated lenses is to a) reduce internal flares and reduce external flares that might give ones presence away. Hence a lot of nature bins have colour coated lenses. Not sure why the different colours, manufacturer choice maybe, or maybe someone thinks one colour looks cooler than another.

ah, I see, thank you Symesie.

Coloured lenses on binoculars scream out CHEAP RUBBISH to me. But some people seem to think that means they must be good.

I have a pair of superb Leicas which cost me £800 a few years ago, and the lenses are completely plain!

[crashtestdummy]

Wow I'm going to ditch my 16" and stop my 22" build because these binos give a better view of Jupiter than either of these scope will!!!!

[scarp15]

I presume that the heading and image implies you can go looking for birds and trains across the surface of Jupiter.

[Pete Presland]

wow!!!!!!!!!!!!!!! i want a pair, not!!!!!!!!!!!!!!

[scarp15]

With reference to birds, they could be Mars(h) warblers on migration

*sigh*

Guess it just goes to show they're still out there.

As for ruby coatings, what I've read is that they were originally developed by a good optical firm for specialised binoculars for hunting, and indeed they worked very well for that. But because the coatings both look dead cool (to unknowledgeable customers) and can 'cover up' chromatic aberration of cheap objectives, they spread like wildfire among the makers of cheap tat.

'Proper' ruby coating are also much less intense than the lurid light-blocking orange often seen nowadays.

Subtle tints on decent binoculars are an inevitable side-effect of the anti-reflection coatings. Simple magnesium fluoride gives a green tint, while multi-coatings can give blue or purple.

Indeed they are, it's not just binoculars, nearly all good quality lenses give a green or blue / purple tint in the right light - which includes eyepieces and refractors .

I acted on an earlier recommendation this week and they arrived yesterday - very pleased with them thus far, cheers.
