Using the rocket blower

Ziggy mentioned that it isnt wise to use the blower without prior washing it out inside to remove any rubber preservative dust inside. Now ive NEVER cleaned my sensor...its got a few spots in there but nothing too worrying.

I opened the valve on the giotto rocket & it looks clean as a whistle in there. My question is...should i give it a blast or leave sleeping dogs lie ? Im concerned that by trying to clean it, i may inadvertantly make it worse ..ie move dust onto the sensor.

Yes andy...im ordering a copperhill shortly.

    i use the giottos in between swabbings - just blow the hell out of it a few times before you do it inside your camera. oh and i keep mine in a big ziplock btw - just to be extra sure no dust gets sucked in :D

    There are quite a few dust specks on there. I circled them in red. Since that picture was on a very clear sky at very spall aperture, I doubt that most of them would show up on normal pictures.

    Thanks Rb...i did see them. Only one on the far right ever turns up in a shot & if it does i just clone it away.

    I never switch my camera off to lens change & open it up anywhere. I always assumed they (ccd/cmos) were dust magnets. Does not appear to be too much of a problem though.

    Gus,

    I have tried cleaning my camera to get rid of all dust spots and haven't been able to do it any better than what you are showing here. I'd say this is OK. Like you, I never really see them except in extreme circumstances.
