About this image

SH42 is an emission nebula about 3,600 light years away in Sagitta, not far from the Coat Hanger asterism. It is also surrounded by a reflection nebula that is not seen in my Ha image. I hope to add some colour later, RGB or Oiii,Sii, but need some clear skies without the Moon.

Processing in Pixinsight.

Captured over 2 nights,31 Aug/1 Sep and 1/2 Sep.
