I've imaged this a few times now, but never in narrowband. I took most of this during an big moon, and just picked the target so I could sort out some issues I was having with the Paracorr. The adapter that threads it into the moonlite drawtube has a few quirks and somehow I messed up the connections and that took a few nights to sort-out. I've also been setting up a new scope on my other mount so I just let this target roll in the process. Stars are less than perfect, but overall I am pleased with the image. Ha dominates in this region, so I fit channels to Oiii.
