Little black spots, green dots, red dots, blue dots often remain in filtered CCD imaging despite callibration.

The healing brush or clone tool in Photoshop works really well and is very simple to use. Just make sure the diameter of the brush is kept to a minimum and the distance the sample is taken of the background from the spot is not too far and does not have stars etc in it and is similar.

That's for Photoshop though.
