BF109 - Can't we just have the gunsight in the middle?

if so the photography methodology was used... keep both eyes open looking through the view finder

The most German gunsights were made by Revi. The one in Bf 109's are Revis too.

If you are using Track IR then yes it jumps back.

To center the sight with track ir just lean to the left and center track ir. This way when you stop leaning you will be positioned behind the sights.

Well all that need to be established is the width of the reflector glass (thus its centre) (which is suspect is wider than >3” (>75mm) ) and the aperture thus FOV of the rectical which will denote if a pilot could use his brain to merge the 2 images (left eye cannot see the rectical when the right can) or if he was required to lean a little &/or close one eye etc.

Okay try this....

Here's an Apache driver's Helmet Mounted Sight (HMS). It projects the HUD and other stuff into one eye only.



And yet the Apache drivers have two eyes...binocular vision.

So what does the Apache pilot see when he's flying around?

Is it this....?



Or is it this.....?




And so with the Revi.

The Revi is installed on the 109 to project its reticle onto one eye only (the right one in our case).

And yet Luftwaffe pilots has two eyes....binocular vision.

So what would our Luftwaffe pilot have seen while flying around?

Something like this...?




Or this.....?

Comparing a ww2 gunsight to that of a modern helicopter whose operator has to be trained to use the sight like you are showing it very clever!!!

It is, because the concept behind both gun sights is nearly identical; the sight is only viewable by one eye and yet, due to the the way the human brain processes stereoscopic vision the image will appear to be displayed in front of both eyes as long as both are open.

I think this post should win.

Lixma, mh. Perhaps we're talking about two slightly different things. I do understand that even if only one eye sees an image the other is made to believe that it also sees this image. This I can understand. Provided they see the SAME image.

What I find hard to believe is that according to your images the brain is capable to add stuff. In the case of the 109 it would be the other half of the circle, something the right eye would not see as it only sees the left half of the circle.
Also the Apache Hud view is strange. As depicted the brain is obviously capable to make the eye without hud see the numbers whereas the eye with the visor doesn't.

I agree with your post, but you have left out a very important aspect in your 109 illustration, in order to actually 'see' the whole circle, you'd have to move your head a lot closer to the revi (so the right eye actually see the whole circle), in other words, you'd have to use Shift-F1 again.

Stereoscopic vision only applies to things in close range. That's why when you look into the vista of Grand Canyon, the whole view looks so flat and picture like.

Notice also how close the HMD is to the pilot's head.

Here's a dude sitting in his cocpkpit with the gunsight clearly covering his right eye. Because he's leaning a bit to the right his right eye is actually right of center of the sight, if he wasn't, it'd be right in the middle.
