Re: Dark blobs on CCD

Definitely dust on the CCD window. I would follow John's advice and get one of those antistatic brush. I have one and it works perfectly. Cleaning fluid would do also, but it more messy and more risky.

I use air from an air mattress pump from Ozark Products. I use it for everything. It is like a small vacuum cleaner in that it can blow or suck depending on where the hose is connected. It is a high volume low pressure pump and it blows really well.
I use this to remove dust from the camera and filters as well as my lenses and mirrors. It is very effective and comes with a couple of sized nozzles or you can just used the hose.
A small filter can be placed over the air inlet, but really I have had no problem of introducing dust with it.
