Description

This is a live stack of 610 x 4 second subs (40 minutes) taken with a Dobson using a rotator and plenty of nudging to keep the image centered.  The FITS file from the Live Stack was  used to develop and process this image. With this longer integration I was able to  use a softer Startools  processing approach than the 10 minute capture from November 8. Mainly  less photographic development, and less filter usage.

Final version tweeked further in Startools to  bring out the core in more detail and distinct color, as well as accentuating  HII and OIII colors.
