Description

A little frustrated with this target. I was hoping the OIII would bring out more blue in the core, but my data just doesn't show it. Also, my collimation appears to have been off and there are some pretty ugly stars in the corners. But I'm really happy with the way the RGB star color came through and I think my noise reduction was very subtle and the resulting image looks better for it.
