After being very dissapointed to find that my new Canon 20D comes with free dust, I ordered the sensor cleaning kit off of the Copperhill website (http://www.pbase.com/copperhill/ccd_cleaning). After reading the tutorial and getting an overall understanding of the process, I attempted my first cleaning of the CMOS. From the website it appears that a few attempts are necessary to remove all the dust on your sensor, but here are my results:

After

The Images were taken on 2 separate days, therefore one has clouds and one doesn't, but you can get an overall idea. If it is of any help, the tutorial is pretty easy to understand, and the cleaning is realatively easy. As you can see the results are not dramatic, but as time goes on I am sure I will get better, more comfortable, and more proficient.

Hope this helps

I have to tell you Ken, that this doesn't look like typical dust. You might want to send the pictures into Canon Tech Support for their take. Or if you have a decent camera repair shop, in your area, get their opinion.

It does loook like you did get most of it though, so maybe a second pass...

how long are those exposures...you have some incredible sensor bloom if those exposures are less than 2 minutes than get that camera to canon!

EXIF data says 1/50sec. at f36. I agree, this is not normal dust.
