Image notes	This is my first image using MaxIM DL 4 as the CCD camera control software.  Auto dithering was done between all subframes for the first time on this image.  The final combination used a 50:50 blend of Ha:Red as the luminance channel along with the standard RBG channels.  Clear filter 9 x 300 seconds data were not used.

 

  This 10nm Hydrogen-Alpha image is 14 x 1200 seconds (4 hours and 40 minutes).

 

  This is a close-up of the pillar area.
