Am I the only one who uses their binoviewers upside down? I started doing it because my binos would only sit squarely in the diagonal when turned upside down, but I like it for other reasons too:

1) With my WO binos, the shortest "neutral" diopter position is with the two thumbscrews parallel to each other on top of the bino. I prefer to have these pointing down and toward me where they are easier to manipulate.

2) It raises the height of the eyepieces by about an inch and a half, and reduces the scope's moment arm very slightly.

3) I prefer how the image looks flipped upside down. Just kidding. ;)

Try it! It's how all the cool kids are doing it these days, I hear.

Very nice, I learnt this from Daniel Mounsey a few years ago. It also reduces sag on the drawtube and I would say especially with weighty eyepieces it reduces the moment arm more than just "slightly". :cool:

I have done it a couple of times when I needed clearance.

And of course it works perfectly well.

I have two pair of Mark Vs though, and both use a twist lock mechanism to secure eyepieces, so nothing sticking out.

Denks and Earthwin also use a twist lock diopter.

Do you also need to stand on your head to do this? :grin:

Only in the northern hemisphere.

wouldn't this make nose clearance less?

Only if your honker is longer than your eyepieces (plus the holders). :)

I like it better upside down. But the two pinheads I observe with find it more difficult to push up than to pull down to close up the IP distance. :smirk: Mike

I tried it both ways and quickly settled on upside down. I have been using them that way ever since.

Only in the northern hemisphere.

For those of us living near the equator everything appears sideways. :grin:

This is actually a better way to observe with the MkV binoviewer - a least with mine - because it allows easier access to the quick change clamping screw. In the more "normal" position the clamping screw is harder to tighten securely. The screw really needs to be longer.
