    relationship of meade and celestron (if any)?

    Meade was previously owned by Ningbo Sunny Electronic, except the European subsidiary which was sold to Bresser IIRC.

    Brightness of 8x32 vs 10x42

    Making abstraction of the 10% brightness difference between a 4.2 mm and 4 mm exit pupil for dawn or dusk observations (i.e. your eye pupil being larger than 4.2 mm) you should keep in mind that the 10x42 view may not look brighter than that of the 8x32, but you will nevertheless have better...

    Zeiss TL = Zeiss ED pocket?

    Jan, your information is a bit outdated, the Terra pocket models are now made in China.

    I cannot See China bins!

    Joachim, I think you don't deal with lawyers often. ;-) It actually makes perfect sense to me. Up to 100% means sometimes/often it is less, but occasionally they hit 100%.

    Kowa Binoculars 8x25 BD25-10GR

    I have the Kowa BD 8x25. I think they're nice binoculars giving a good image, and with just the right size and shape for comfortable handling despite being small and light. Quite good build quality. Nice compact pouch too that makes them easy to stow away in a bag or large coat pocket. The one...

    Victory model between Dialyt & FL

    There's a story about the Victory redesign in the old Better View Desired archives, sadly the illustrations are broken now: https://www.cloudynights.com/BVD/Zeiss-Tries-Again-for-Victory.php

    The Remarkable First Zeiss Conquests

    Thank you Canip. Less contrast kills the idea, I think.

    The Remarkable First Zeiss Conquests

    There's a Conquest 8x50 that's been on eBay since forever. I know about the narrower FOV and the lower light transmission compared to later Zeiss binoculars, but other than that, how would this one rate compared to current 8x42 binoculars in the €1K price range?

    Zeiss 10x54 HT impressions today

    No that is not how the HT diopter works. No pulling or locking involved.

    NL Pure 8x32 and NL Pure 10x32!

    With an identical bridge connecting them, it is unavoidable that a pair of narrower tubes cannot open to as wide an IPD as a pair of wider tubes can.

    Zeiss 10x54 HT and 8x42 SF - an informal review and first impressions

    Nice report, and a very interesting comparison. There isn't anymore the need for guessing the eye relief now that Pinac has objectively measured them all: 16 mm for the 8x42 SF : https://binocular.ch/zeiss-victory-sf-8x42/ 14 mm for the 10x54 HT : https://binocular.ch/zeiss-victory-ht-10x54/ I...

    Simple Contrast/Comparison: Leica Trinovid HD vs Tract Toric UHD (10x42's)

    Leica's website says the Trinovid HD 10x42 are 113m/1000 m = 339ft/1000yds = 6.5°. CameraLand has the spec wrong.

    For 10x40BGA Dialyt owners only ...

    I never had the Dialyts but a friend at university bought one, end '80s. I was green with envy ;-) Very peculiar instrument, I often think about that first viewing session with it. It had massive angular magnification distortion; I'd never seen that before.

    For 10x40BGA Dialyt owners only ...

    I always thought it was a 10x40. Did the Dialyt come in 10x42 too?

    wavefront error

    It would very much surprise me if the Absam Ring has anything to do with a wavefront error on one of the optical elements. It is just unlikely that there would be a localised gross grinding/polishing error. More likely in my opinion is that it is an interaction between spherical curvature of...

    avian ultra light 8 x 32

    Avian is the house brand of Ace Optics. They used to source their binoculars from Kamakura, maybe they still do.

    Dodgy vision or Binocular fault?

    In 44 years of using various binoculars, I've never seen a perfect single circle as the combined FOV. My right eye has a different correction than the left eye, as I found out in my early 40's when I suddenly needed reading glasses. But I still don't use glasses when looking through binoculars.

    what will be brighter in dark hours - Swarovski EL 8.5x42 SV or Meopta B1 8x56?

    All true, but the OP asked about dark hours and then, given his young age, it is the exit pupil that counts. The 8x56 will be twice as bright, give or take the few % difference in transmission. This assumes an eye pupil size of at least 7 mm in the dark.

    Vintage binoculars - United 15x65

    My first telescope back in the late '70s was a 60mm with 700mm focal length that looked almost exactly like the one in that United catalog.
