It just looks like the typical bias, dark current noise, and interference noise that are pretty typical for all CCD cameras. The pictures were posted as soon as they came in, with no calibration. They were probably stretched to the limits to bring out ring detail, which also stretches all the noise sources. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |
