In AH, cross cursor on gun sight does not move with head position.
But in real gun sight, the cross hair cursor moves when you change your head position.
So that you donft need to care about your head position to get accurate aiming.
Here are some pictures taken through gun sight of T-34.

How does the sight know where your head is??
-
Meza,
Sorry bud but from what I saw in the photos it looks like the prove that what we have in AH is correct. Unless your head is aligned with the sight it slides of to the side and the reticle fades and partly disappears. In the first picture I can't see the reticule at all.

OPL GunSight of Aces High is not working accurate then moving head position.
(http://www.ceres.dti.ne.jp/~batman/jg68/images/crosshair.gif)
The cross hair should keep to point to the direction of discharging of bullets even if pilot moves his head position. OPL gunsight must be made so.

You guys are gonna have to explain this to me.
A reflector sight as far as I know is just a light shining on a piece of glass. If you move your head the LOS shifts and it isnt as bright, just like its modelled. Only thing special it does is have the sight focused to infinity so target and sight are both in focus. Plus you only have to line up 3 things instead of 4 with ring and bead sights.
Only thing they need to do is flip that sunsheild down on my 109.

chisel,
There is no hi-tech magic in WWII sight. The reticule behaves like it exists at infinite far away.

>Unless your head is aligned with the sight it slides of to the side
In my PC, AH's reticule dose NOT slides off while my head slide. It just looks like fixed on sight glass. That is the problem.
The picture on top row in my page just shows outward look of the gun sight.
Three pictures on 2nd row show how the reticule looks in the gun sight.
Batman,
Thanks help (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif) That is what I want to say.

Batmann PLEASE hook me up with that sight you're using! I'm growing sick of the stock one. The one pictured in your post is very similar to the one I use in WarBirds and I have to have it. (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
Thanks!

The site is just a bitmap file in the "sites" directory in your AH directory. Its called "default.bmp".
Make a backup of your original sight file. Then open "default.bmp" in PAINT or Paint Shop Pro something similar and use the original as a size reference for creating your own. Then save it as "default.bmp" into your "sites" directory again.
Note that the aspect ratio (vertical/horizontal proportions) is not 1:1. If you make it 1:1, AH will shrink (squash) it slightly in the vertical direction when its displayed (see batmann's site above).

Aha... OK Windle
(http://www.ceres.dti.ne.jp/~batman/jg68/images/batmann.gif) (http://www.ceres.dti.ne.jp/~batman/jg68/images/batmann.bmp)
Click this, and get "batmann.bmp". Copy it to your sights\default.bmp.

Aha... OK Windle
(http://www.ceres.dti.ne.jp/~batman/jg68/images/batmann.gif)
Try to save this image to sights\default.bmp.

I think what meza and batman want to say is...the real OPL works like this picture.
(http://www.ceres.dti.ne.jp/~nabezo/Gif/realhair.gif)
It's a biggest merit of using OPL. Because of using OPL,pilots can be released from telescopic gun sight whitch force him not to move his head against G.
Thank you.

Thanks nabe, What we need is all in your picture.
Letfs see what happen if the reticule is fixed on the sight glass.
If the pilot's eye is placed at 18 inches far from the gun sight, and if the range to the target is 500feet (6000 inches),
6000/18 = 333.33
This mean slide movement of the pilotfs eye will appear as an error of 333.33 times.
If you shift your face just two inches to the left, bullets will go through 666.66 inches (55.55feet) left of the target.
No fighter pilot wants to use this kind of gun sight.
Real gun sight is here.

I guess what meza, nabe and batman want to say is that the reticle of the gunsight is not focused on the glass itself as shown in the picture by batman. The sight picture of the reticle was focused at infinity so there was an illusion of a glowing reticle positioned far out in front of the aircraft and not on the glass.
If you were trailing a target dead on in the reticle, it would stay there even if you moved you head, provided that your sight line stayed in the confines of the sight glass. If the reticle was focused on the glass, slight movement of your head would move the reticle away from the target rendering it useless.
If you shoot pistols, you may have come across an electronic dot sight that uses the same principle as an OPL sight. The current sight in AH is like shooting through a scope. Your eye has to be lined up just right to make it work, which is one reason that fighter scopes moved away from telescopic sights.

OK,
I talked to some guys on the LW newsgroup.
I was informed that there is a display setup in the Nat. Air and Space Museum in the US with German,British and American Reflector sights that are powered and you can look thru.
He said if you moved your LOS the reticule faded out.
If it works a different way Please explain "how" to me because I cant picture it (Honest requset no sarcasm is meant)

What a chance to plug the next CD - Aerial Gunnery... This page is way reduced in size and converted to black & white. The real ones are at 300 dpi and most all are in color...
Here is the proof but not the explanation...
(http://www.oldmanuals.com/n9.gif)
I'll put up a notice on the web site when this one is ready - http://www.OldManuals.Com (http://www.OldManuals.Com)

chisel,
If you have a small mirror, please try this.
1.Draw very small circle on a piece of paper.This is your rectile.
2.Put the paper on your desk and place a mirror slanted (45deg.) on it.
3.See your reticle reflected throgh the mirror and move your head.
Dose the reticle seem to fix on the mirror?
OK, this is not exactly same as OPL because there is no lens between mirror and the reticle. But at least you can see the reticle slides on the glass.
If you have a lens and place reticle at focus point of the lens, you will see the reticle slides on the mirror with your head shifts and it is fixed related to infinity far point.
##How about this question?
How can you fix the reflected image of reticle on your sight glass(mirror)?
This is far more difficult.
Sorry about my poor English writing.
Thanks.

With your head shifts, cross hair might fade, (especialy with point light souce) and also slides on the glass.
My friend who has K-14 gyro computing sight, said "The cross can be seen only from straight aligned point because it is so dark due to its rusted mirror"
But that doesn't prove anything about cross hair slide or fixed.
With proper "frost" bulb and clean mirror, I belive reticle will not fade so quickly with your head shifts.
Thanks
