that very interesting set of ORs reminds me that it was Steve Gottlieb, the astro-animal hissef as Jamie says (I think I got that all correct) that had first suggested the target to me in what I think may have been 2004
I sent him an email an asked for some suggested planetaries that were big enough to be interesting in an amateur's scope and this one was on the list he gave to me.
As I am recalling, the object wasn't well placed for my backyard at that time and I think all I took were a few exposures that were too faint to be useful.
For some reason I decided this year to return to it.
It is a cool target and the serrrated edges on the eastern side are really interesting to me.
That and the blob to the south of it (north is to the right in my image)
