this is always an interesting region. This was my first light image taken with my FLI Microline ML8300 last summer. It is a total of 11H 45M and was taken under a full moon using FLI Research Grade Filters.

It was a hot evening, well into the high 20s (deg C) all night, but the camera ran well at -35C operating temperature.
