Description

This was my first ever imaging run with guiding. I had only a limited amount of time before M20 disappeared behind some trees. From my northern location in VT this is a challenging target as it is never very high in the sky to begin with.

This evening was warm and my DSLR is uncooled. As a result there was banding present in the images. I also took some 300sec shots of M33 and those longer exposures showed even more banding than these 180sec 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 primary purpose of this imaging run was to test my guiding setup. The guiding worked well throughout the evening/night...right up until my laptop power supply died.
