Greetings all..... I'm soooooo glad I found this forum & thread, as I've had exactly the same colour problems described previously.
I bought the StarCam for use as part of a DIY security system (so the IR use for low-light was a bonus), but in strong sunlight, like we have today it's terrible.
After reading the comments about the IR sensitivity and plexiglass I had a revelation - aren't normal safety glasses/goggles made from plexiglass? - when I get home (where the cam is) I'm gonna try fitting it with safety specs to see if it solves the problem - watch this space!!
