This is another image out of Swan Reach Imaging. This one is of the small planetary nebula NGC7009 or the Saturn nebula. It certainly does look like Saturn in very poor seeing.
It lies around 2000 and 5200 light years distance. It has an apparent diameter of 0.6" and presents quite small even when imaging at 0.94".
For this object I used 120 second sub exposures to prevent blowing out the core detail too much. I could not detect if there was much of a halo at all in the OIII.
