Fantastic object that is on my bucket list. Folks who have not aimed a camera at this cannot fully appreciate what a difficult target this is. It is VERY faint and super large, making for some challenges at getting a good image. You certainly have suceeded here - love the Hα and OIII interplay. Can you give us some more details on what the remote gear was and the total integration time, etc?
Super job, thanks for sharing!
