Hey guys.

I noticed some dust donuts on my preview screen while Saturn was whizzing past on it this morning..

I'm not sure if it was the barlow or the CCD chip, i've cleaned the barlow tonight and it was dirty, hopefully that's all it was.. but if it turns out to be the ToUcam CCD chip, how should one clean this delicate object? And where does one purchase the required implements?

Your advice appreciated!
