Description

Cassiopeia along with the hearth and soul nebula.
For this image I used 35x150s shots. Due to the rising moon I had a strong gradient in the image towards the left side.
Also because the camera is unmodified I had to use masks and push the red channel quite a lot to bring out the nebula.
