    Smile Hi!

    Hi JG!

    Thanks! You are my inspiration for wanting a pair
    I'm fascinated with this line of vintage binoculars now...

    I may have an opportunity to purchase a pair of Asahi Pentax 12x50's, 5.5 degree view (in excellent condition). Any thoughts on that one?

    Clear skies,
    -Al

    Hello Al,

    those 12x50, for how much?

    The apparent field of view would be 12*5.5=66deg - that's great.

    Below find please a link to the military vintage binoculars:

    Japan - Collecting Military Binoculars

    I cannot open the link "Newspapers - Page 8 Adv...." - they give me just the terms.

    Hello Al,

    another link to the military Asahi Pentax vintage binos, commenting on the coatings:

    Asahi Pentax 10 x 50 Binoculars - Any Good? - BirdForum

    I'd agree, those binos are not the best for birding, as the coatings dim or even cut the red and the far blue light. However, I find it helpful on large emission nebulas, as those binos have a maximum transmittance close to H-Beta through OIII.

    Best

    You should be able to just tick the box that says "I Agree" and you should be able to see it. Very interesting Ad. I would have cut & pasted it - but couldn't.

    Hello Al,

    My problem might have been, whenever asked to "agree", I'll hesitate, and strt thinking.

    ...From the Ad, we now know that the weird coatings are made to block UV & IR
    Some people (Birders) have complained of a bluish/green tint when using these.
    I suppose it's not that noticeable when used for Astronomy.
