M20

Recommended Posts

OK, it's common - everyone has shot it, but I wanted a nice easy target for first light with a new camera, and was in the right place at the right time!

 

M20 is actually unusual in that it has an open star cluster, an emission nebula, a reflection nebula, and a dark nebula all in the one object.

 

This image is 2 hours total exposure, RGB only. ASA 10N at f/3.6, DDM60, Moravian G2-8300 with Astrodon filters. Seeing reasonable, best SQL reading 21.09.
