Thanks! Here's the info and the vendor that I purchased the camera from: [link] Basically they remove the factory white-balance filter, exposing the CCD to all of the wavelengths of light that are available. Hydrogen-Alpha emission nebula like this one emit a Red color that standard digital camera's have these white balance filters to actually suppress these rich-red colors a little bit, down to about 20% of what the CCD is capable of. Removing the filter means that you can take images like these in 1/5th the amount of exposure time. In other words the image doesn't have to be 15 hours worth of exposure, 3 hours does the trick! Big difference! Removing the CCD's white balance filter also means you can do near-infrared photography, UV photography and very low-light photography.
