Description

This evening was warm and my DSLR is uncooled. As a result there was banding present in the images. I also took some 180sec shots of M20 and those shorter exposures showed slightly less banding than these exposures. Most of my imaging will not be in +20C temps, at cooler temps the banding is much better controlled in my EOS 60D.

The resulting banding caused me some real headaches in processing. The horizontal banding removal tool in Astronomy Tools did a fair job but it was not up to the task of removing the final traces of banding.

The primary purpose of this imaging run was to test my guiding setup. There were 300sec exposures and every frame I shot was used in stacking. There were no rejected frames due to tracking errors. The guiding worked well throughout the evening/night...right up until my laptop power supply died.
