Trifid Nebula

The Trifid nebula can be found in the constellation of Sagittarius about 5000 light years away, being a bright emission nebula that can be seen with binoculars. The nebula appears very low in the sky here in England, and is not an easy imaging target due to the air pollution and murk being so low down in the sky. Special narrow band filters and looong exposures are required to reveal good detail and structure.

This image was acquired with more modest kit, back in April/May, when the sky was very clear and transparent, due to the depleted pollution from industry and aircraft during locked down. Although there was still a light pollution dome on my near horizon, the severity of the image color cast in my image was easier to reduce in the final image, due to the cleaner sky. Back to normal now, couldn`t achieve this image again.
