benny: the gunsite is a custom one that an old squaddie made for me. PM me with your email address and I'll be happy to email it to you. Go to SimHQ and look for Andy Bush's articles on aerial gunnery to get an understanding of what the "rings" are used for.
Kermit: Virtual Dub 1.6.11. I haven't checked lately to see if there is a new version out. I've used the HSV filter to tone down the colors - sort of like dulling colors on plastic models to simulate scale effects. The HSV adjustments also bring out the details of the aircraft models a bit more too (e.g. panel lines etc.).
