Hi Reiner,

fine object that I have to revisit, thanks for the idea.

Under good transparency it was never a problem to see the PN as a very faint glow around the bright CS. I was also of the opinion to see differences within the glow. For me the eastern part was always a bit brighter. But it does not fit perfectly with the pictures.

I remember a lecture of Bernd Gährken about CS in PN for small aperture. Funny, but this CS is one of the few which is visible in binoculars
