Dust and gas clouds in the Horse Head Nebula

06/12/2019

The Horse Head Nebula just under the left hand star of the belt of Orion (the brightest star in this image - it's rotated 90 degrees i.e. north is left). It's 1400 light years away. This is two frames stitched together for wider field of view, 5.5 hour exposure in total (both exposures combined in bortle 5). ZWO 1600MM with ZWO HA filter, 300 sec exposures at gain 200 offset 50. Two frames from Esprit 80 combined. The stars digitally removed so that you can better see the structure of the nebula.
