Yeah I remember yours now Steve, nice, it is a difficult object to process huh?

It's truly fascinating how many of these faint PN outer shells that have been revealed in detail by amateurs in recent years.
Thanks SkyViking Sigmarson Olofsen

This was difficult to process, after heavy stretching the OIII was pretty bloody noisy, so then the noise filtering had to be done very carefully so as not to remove details but also and perhaps more importantly, not to add details or features that weren't there! I think I succeeded in this anyway...but I would love a 20" to make life easier
