I didn't say I found the others dis-pleasing. But WOW look at the structure you have brought out in the Dumbell, and the twists in the Ring.

They are pretty darned impressive oh bespectacled pyromaniac you !
Its ok Paul i was only joking, I thought M57 would turn out ok, but that deconverlutedthingy option seems to be a big plus. Is it there in AIP4WIN?
Chris,
Yes AIP4WIN has convolution routines
