It's called "prime focus"

I'm still battling with clouds!!! I have yet to take a single photo, without a cloud obscuring my vision!

Getting a handle on the webcam settings!

Best thing this far, is "prime focus". Which basically means - you have no secondary lens, only a primary. It seems to work rather well! Registax certainly likes it a lot more.

There is of course some minor touching up being done (unsharp mask, change to b&w - and dropping images down to 320x240 from 640x480)
