Oh geez, you're getting some really high signal to noise ratio there! Some really nice details in M16 and the Statue (4 subs - wow!). With the M16 stuff, did you get a chance to capture and run some straight RGB data? That in combination with luminosity masks will pull those magenta star back in shape.

Some of the stuff there (not all) has some real value with astrophotography.
