[AZ-Observing] Re: All Sky image as a preview for next weekend

Brian, Loke Tan captured this really well with an 8 " Schmidt

I was surprised at how much it stood out, I didn't do any local enhancement on 
it at all.

       Very nice shot.  I was surprised to see the very large nebula
  centered on zeta Oph, which was something I hadn't known about, or maybe
  only vaguely.  It is spectral type O9.5V, plenty hot enough to ionize
  whatever's around it, but evidently there is only H-alpha emission---
  though the color balance of the image may be emphasizing that.
