Sure was weird. I just recleaned the glass in front of the CCD chamber again.

Maybe? Not sure... Interesting theory

There have been some infestations of flying ants around, and the scope is set up near my pool- but they're the normal 1cm size. Not sure about microscopic ones?

Does it disappear when your cooling is off?

Hey Alistair, yep did that - it's the only way I could figure out how to access the ccd chamber window. I spied a teeny tiny dust mote that i was able to remove but that was all. Havn't tried testing uncooled, are you thinking the fan is sucking something in?

Thanks for all your input everyone. After exhaustive cleaning it's a big improvement but I'm still very wary of something odd going on!

Cheers
Andy
