I had a go at collimation today, couldn't find any 35mm film containers, so i just used a piece of cardboard with a 5-6mm sort-of circular hole in the middle. Seemed to work OK, i had a quick test just then on jupiter and it looked much better, and that was with no scope cool-down and slightly worse seeing, so I was happy. I'm thinking of getting a collimating eyepiece though, $29 from Andrews for something that should be pretty useful sounds pretty good to me.

The microelectronics engineer in me wants to have a go at a DIY solution using a laptop, it'd be an interesting project.
