Very nice Diego! You always do an exceptional job of bringing out faint stuff even with short integrations and you've done really well with this one too, even considering the 12hr integration.
I've just started on this one myself and I was happy with out much I'd brought out with 5hrs of OIII data, but you've done better.
Beautiful image Diego! It would be great to appreciate a larger size version too, I couldn't see the link unless I am missing something
