The Crab Nebula Messier 1

Only 44 minutes of exposure, the nebula is clearly imaged. However I don’t like it too much, as the Gain settings wasn’t OK I suspect something went wrong during processing.

The background was way too noisy, even for 44 minutes, and as a result has been made too dark to remove some of the color noise. Also sharpening at some point was too much.

Lots of sensor real estate is waisted with this object being soo small. Probably better to give it a try at a longer focal lenght.

It’s really mysterious to see the results of a star exploding a millenium ago.
