Description

This is a blend of Ha and OIII (~60%) and RGB for the emission part of the nebula while the outer areas are straight RGB. I especially like the additional colors that the OIII filter provides. The RGB is from an ASI071MC, 150sx70, gain 50. The narrowband data were 2-panel mosaics, each 300s x 30 using an Atik 460ex.

Description: If one isn't careful, Startools can create some nasty artifacts around stars. I've fixed most of those issues with this revision.
