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. :)

Not that this helps, but it's pretty neat don't you think?

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...?

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.

I could be wrong but revi is a shortened reflex vision? (whatever that was in german)

Why isn't this post getting more love? The 109 gunsight lined up with the gunners right eye and stereoscopic sight compensated for the rest. This really is what a 109 gun sight should display if this SIMULATION is SIMULATING a pilot with TWO EYES.

The fact is, no matter how realistic a sim is, it must compensate at least just a bit for the fact that this simulation is being displayed on a two dimensional display (don't get me started on 3D displays that only use one of the ten visual cues to simulate human stereoscopic vision) with image resolution that falls far below the image quality of the average human with two eyes.

The fact is that a human being with eyesight comparable to viewing the world through the best computer display available on the market wouldn't have the vision requirements to be a combat pilot in WWII seems to be a fact that a lot of people here seem to ignore.

Well said Evil Joven

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!!! :rolleyes:

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.
