Description

The emission nebula, known as the Wizard Nebula, cradles the open cluster NGC 7380.  Not an ideal target for a modified DSLR, but with enough data to show a hint of blue within the base of the cluster.

Title: NGC 7380, Wizard Nebula (undrizzled version)

Description: I like everything about the undrizzled version better than the drizzled verision, save for the zoomed in appearance of some of the stars.

Title: NGC 7380, Wizard Nebula, revised with SPCC and variation on a twist

Description: This revision was developed twice along two different lines to compare: 1) Fully developed without separating out the stars with StarXTerminator (the Combined image) and 2) Completely developed separate star and starless images using SXT in the linear stage then recombining after both were fully developed. As expected, the Combined image started to suffer from star bloat, even with careful use of GHS, however, the star colors were better. This makes sense since the alterations in the starless image absolutely impact the final image when the stars are added back in; some signal has changed from the original balance between the two.

Which image is this revision? It is the Combined image that was developed not using STX. At least in this image at the end, the Combined image looked better once the stars were reduced; the image benefited greatly from Bill Blanshan's Star Reduction Tools in PI and putting the two side by side, I could not say the nebulosity was any better in one or the other but the stars were a bit better in the Combined image.

I am now going to be compelled to develop a combined image as well as a SXT separated star and starless image for a while, now, until I can figure out a pattern.
