Yes, thanks! I hadn't heard about that. I've only handled a FP once and its knob must have been unlocked, as I was able to pop it up/down normally for adjustment and thought no further about it.

Yes, I notice how my knowledge that I'm supposed to see rings influences what I "see", or think I should. If I didn't know that already, I wouldn't guess it, I'd only say that Saturn was wider in...

We tried that BTX once, it's pretty amazing. Only thing is, you have to keep adjusting the interpupillary distance to share with different observers. (Still resisting a spotting scope...

I can see them easily with any binocular at all, and think most people can. (Sometimes fewer than 4 are visible.) I think it's the proximity of the rings to Saturn that creates a need for greater...

Viewing Saturn

Why is it that ordinary binoculars (even 15x, I'm using SLC) will show Jupiter and its moons beautifully, but with Saturn there's only a vague sense of oblateness? So tiny an image won't show much...

... Don't forget they'll have considerable resale value also, even after 20 years. (I use this calculation to rationalize long-term ownership of alpha binos myself.)

The 42mm EL and SLC are both excellent, so just try both and see whether you see much difference for the price and which you prefer. Likewise try 8x and 10x (some like me prefer 10). It's really...

It's a matter of taste. Some people care only about the sweet spot and aren't bothered by problems with the rest of the field. Others (like me) are. That's principally why I haven't used any of...

Sounds good to me! Then again, everyone points out that the high end of the bino market is much smaller volume, so maybe Meopta is right to have just introduced a third range that's even cheaper...

I've never seen a grey Victory 8x25, I thought they were all black. (Maybe you're thinking of the 42mm SF which at first was grey?) Your opinions resemble those of many here, including the fact...

There's a family resemblance in overall color, and I find the difference rather subtle in most situations. We were just out today with a 10x32 BN and UVHD+. The UV seems a tad brighter and more...

Why is twilight transmission lower than daylight?

Meopta is the only brand I've seen quoting separate transmission figures for daylight (presumably what everyone else states?) and twilight, which typically comes in several percent lower, e.g. 84% vs...

Well, they are rather minor mechanical improvements. (There may also be a new hue for the green armor.) Not exactly advertising blitz material; 1.1 indeed, not 2.0. (I'm very curious how much more...

"Better eye cups" is debatable... some UV models (42, never tried 50) were unusable for me because the eyecups wouldn't extend far enough for the ER. And I've never needed steps; in or out works...

I thought there was only one mirrored (non-TIR) surface on a SP prism pair. What have I misunderstood?

Interesting PR material there. I always wondered how they handled the issue of having sold...

The UVHD+ will be lighter weight and slightly brighter than the BA. I've also noticed that UVs bring out some subtle details in low-contrast subjects better. But these are modest improvements. The...

I doubt it was a blackbird, but female yellowthroat is another possibility. I guess we'll have to go back for another look. Thanks!

Thank you both. I don't have a P* version here to compare with, but it's useful to know that the lack of phase coating (confirmed by experiment) is the real issue with this old bino. It's...

Optical design of 1980s Dialyt 8x30

This argument is absurd. 30-40 year old Japanese binoculars didn't even have internal focusing, much less integrated diopter knobs. There is no problem here.

Hello and welcome 42za,

My diopter knob also moves very easily or lightly, once unlocked; it has no click stops like Swarovski. But it works of course, and the lock is firm and allows no play. I...
