Utterly superb result Marc.
The colours are lovely. Your 30 hours at the helm have produced a very smooth and definite result.
(To the unbelievers: We just don't understand the popular terror of seeing green in an SHO image. If the celestial reality contains areas of relatively fresh gas with not too much hard ultra-violet, then compared with the rest of the image, those particular areas with have predominantly H-alpha emission without too much OIII or SII emission, and it should, must, be green. If it isn't, there's a mistake, you're not being true to what's up there. Marc's got it exactly right: parts of this image are nowhere near as violent as say bits of the Magellanic clouds for example).
One to print really big and put on the wall. Bravo!
Best,
