I am using darks and I'm planning to experiment with bias frames soon. I am also going to start using flats once I get a light box together... I'll see if that helps with the banding, but my suspicion is that it won't. In my case, at least, it's an artifact caused by small, bright objects and doesn't seem related to read out noise, thermal noise or uneven illumination of the sensor. Thanks for the suggestion though, Greg! I'm sure that adding bias frames and flats to my regime will be a good thing. In the worst case I'll just have to buy a real astronomical CCD camera, something I'm keen to do anyway
Cheers,
Rick.
