Description

I collected a lot of data on this nebula over the last couple months. It really just became a place to park while I was doing other things. All told, the integration topped out at 35 hours. While I still plan to do something more with the data, I just started messing around with some of it. Here I took 26 total hours of Ha, OIII, and NIR data and mixed it together. The palette ended up looking a lot like SHO in the end, but its a rough blend of what I'll call NIRHO. The star colors looked just plain great and natural, so logically, I removed them to look at a starless version. It was a bit of an aimless processing stroll that ended up looking kind of cool. Had I known the destination, I probably would have run deconvolution and noise reduction in PI, but I was too far down the road to turn around. For me, anyway, I was outside my normal process.

So, enjoy a first cut at the Pacman project.
