John, Rick ad Bob,
Thanks for the comments regarding my image of NGC4361. I was happy with the detail and the colour (in the most part) that I managed to tease out of this unusual target. The part that I really like is that I can see discreet areas in the pn. There is the outer shell of dark magenta "ribbons" which overlay the blueish clouds which in turn surround the brighter, whitish cloud. In the middle of the cloud is the progenitor star which has a dark area around it. The dark area apparently is real - it can be seen in unprocessed data - and not a processing artefact.
Thanks once again,
Cheers,
Mario
