Hello Juergen
Ok thanks.
This thread about the Nikon's Astroluxe/Standard are going to be (IMO) a quite important source of information for all of us (and maybe of course for some here in the future) about their ''real'' optical characteristics...which however (with or without in any way) are some the very good ones in any respect whit no doubt!
cheers Pedro

Hi Pedro,
you and all others are always welcome.
If on interest visit our German side and see
my "fight" for the excellent Nikons against
Fujinon, Zeiss and other famous German binos.
http://forum.astronomie.de
You can find 2 big posts concerning Nikon SP under the same synonym "jrweisner"
The language is German but translation tools are available worldwide on the web.
see you

Hello Juergen ok.
I will read the comments there using a german/english translator...you know...I don't understand one only word in german and my father was a Austrian citizen who was born (and lived there for years and years) in Viena...it's of course a shame!
Regarding the Laser test..I noticed you used at your test a red one - according the Edz/Rick the Laser should be a green one - if you get a test in the future using a green laser please let us know if the results show something more, I don't know if you will find something more...but...
regards Pedro

Hi all,
I´ve got now an offical statement from Nikon Germany.
They have asked an expert in the Netherlands.
Here is his statement "These Binos have no ED glass this red line is for design point of view to seperate from other Marine Bino to create a high grade image"
That´s exactly what Rick has written yesterday.
I asked some Nikon stores often before and they have told me always that there is definetly ED glass.
I regret having stated the wrong things and want to clarify this hereby.
As I have also stated this in the german forum, I have to clarify it there as well.
Regards
Juergen

The dealers here also make the same statements in their ads, so the confusion is understandable.

Hello
Great! At least we know now the exactly truth.
Regarding the ''3º model'' present in some Website stores in US - I wrote to one of them just asking about to comfirm if they are 3º or the regular 4º - they told me that they in fact have 4º with 72º wide AFOV and that is just a TYPO.

Hello,
this was my second little failure.
I realized it for rightness in the information by some
american dealers..
Nikon produces only the 4 degrees 18x70 model.
Now all is clarified.

< Now all is clarified.>
Thank goodness for that ! :-)
I must admit , I had my doubts about that " alternative " 3 degree TFOV version all along .
Seriously , though -- thank you Juergen for making the efforts to find out the truth about this matter , and for letting us know , and for being honest enough to admit your previous information was incorrect .
Regards , Kenny

Thanks for the link, Juergen. I have an old Nikon brochure with the same internal view which I tried to describe in a post a couple of years ago. For some reason my computer screen doesn't show the entire eyepiece, which is 5 elements in 4 groups arranged just like the Fujinon 7x50 FMT-SX eyepiece (the Nikon came first). Of course the unique feature of the design is the (possibly aspheric?) element placed just behind the prism cluster. This should probably be considered a third objective element since it does not move with the eyepiece elements and is located just in front of the focal plane of the objective. This surely accounts for the superior correction for field curvature in the Nikon SP binoculars compared to the Fujinon FMTs, which have good correction for off-axis astigmatism but show considerable field curvature compared to the Nikons. This extra element could be the location of the mysterious "SP" glass. It is not present in the 18x70, which doesn't carry the SP designation..
I'm also happy to see the pervasive myth of an ED objective in the Nikon Prostar/Astroluxe corrected in this thread.

AND that the 18x70 does not have the SP feature that the 10x70 has, if I understand correctly.

That´s correct.
But we can be satisfied with this bino not having the asperic element, can´t we?

Hi
About the ''true'' Ed element on some high powered binoculars...have someone tried the MINOX BR ED 15x58??
I am curious about how the Minox 15x58 works with their ''real ED element'' regarding the CA, sharpness, true colors, etc, any comments?
regards Pedro

Pedro,
Some weeks ago I checked the Nikon 7x50 SP against the Zeiss 8x42 FL T*
Just for fun.
Normally you shouldn´t compare a Dachprism to a Porroprism.
Also you shouldn´t compare a higher magnification to a lower.
However the Nikon was better with LESS CA and MUCH BETTER with an extremely sharp image and best view of sharp edges.
Please note that the Zeiss uses a Fluorite element in their objectives!!
Believe me the Nikons are the best binoculars with porroprism design worldwide.
If I look to some other manufactors, I like to ask the question Lessons learned?
If Nikon would use ED objectives too, the optics would bee too expensive for the market.
If you want a perfect binocular with the the brightest, sharpest image, you should always use a Nikon SP.
If you want a perfect astronomical and terrestial binocular you should use the Nikon 18x70 WF.
Juergen

Please tell Nikon I'd like a 12x70 in that flavour.

I can do so.
