Great image mate. Yes looks like you’ve taken the harder route but still.. super smooth and stacks of depth and detail! Lovely composition and the Ha is really well blended too. Excellent work all round!!!
The issue of large stacks and 100s GBs of data is not insignificant. I’ve actually right now got a bunch of data on the good ol’ Sculptor turning over in APP. it’s been going for about 24hrs and only 30% done…

and I’m not sure whether the stack settings will be ok and might have to go back and do it all again…
