Benji, it appears that Stathis Kafalis noted annularity in
this "knotty" Abell with his 24" f/4 scope. And he goes on
to log what sounds like some very interesting structure in
it as well, with higher power and an OIII filter!

IAAC has archived a few successful attempts at this large,
challenging Abell, including one from Eric H., another by
Yann Pothier, and even a claim of seeing it with a 13"!
 http://www.visualdeepsky.org/search.cgi?catalogs=Abell&ids=71


The Adventures in Deep Space site includes it among Steve
Gottlieb's "Best Abell Planetaries: Summer", and includes
his observation of it with a 17":

Clear skies!
