We amateur astronomers have for years had available a sighting device based on the very same principle of the optical gun sight. The original was called the Telrad, and a more recent derivative is the Rigel Quick Finder.

Both employ back-illuminated reticle patterns which are collimated by a bi-convex lens and then reflected off a 45 degree tilted reflector glass.

In the image below, we're looking at the front of a Rigel Quick Finder... the astronomer would be peering through it from behind and to the left.

Neat! I guess you astronomers use it for accurate position measurements?

But where is the trigger button? And do you also use TeamSpeak to shout "Direct hit! Target on fire! "Death Star" has been destroyed!"

Cool,

I've been eyeballing a sight for my Bow shooting.

I have a trigger for that http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

Are you trying to imply our use of gunsights in Il-2 isn't real?
