Hi Mike I was only pointing out the presence of the (Galactic Cirrus) Not having a go at the image. I think it is wonderful and would love to be able to produce an image half this good.
As for the IR emmission or Galactic cirrus, what ever you want to call it, it is evident probably because of the extreme exposure time of the image and wouldn't be noticable in a smaller stack of these images.
t is what can only be called a very unusual sight in images from amatuer astrophotographers images where the IR band is filtered out.
Not having a go at the image. Yoking = Joking in a big egg shaped galaxy.
