M16 Eagle Nebula Hubble palette


Recommended Posts

In the last few nights I was able to catch more data of M16. I got much better Ha data (better seeing) and also some OIII and SII data, that I had to stretch quite far). In the end I'm happy with the result (it's at only 20 degrees elevation here...).

I did some quite extensive processing, also using star masks and the narrowband data to create natural color stars...

TEC140 / QSI583ws
6x900s Ha (4,5nm), 4x900s OIII (3nm), 4x900s SII (5nm)

That's beautiful, it has great depth in the light.

Looking at this, it suddenly struck me how enormous these structures are... All those tiny dots are stars, the nebulosity is vast isn't it.

      This image is a cropped and rotated version of the M16 image to emphasize the famous "Pillars of Creation" part of the nebula, made popular by the HST image of the same name.
      The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal.
      The total exposure time spent on this image was 20 hours and 57 minutes consisting of the following subs exposures:
      RGB: 13x15s, 19x30s, 17x60s, 12x90s, 17x120s, 15x180s
      HII: 2x600s, 9x900s, 4x1200s
      OIII: 1x600s, 8x900s, 1x1200s, 11x1500s
      SII: 2x500s, 14x1800s
      All at ISO1600.

      My latest image of the Eagle nebula (M16/NGC6611) in the constellation Serpens, this time imaged through narrowband filters using my 8" Celectron SCT, at F10 - 2032mm focal length, with my astromodded and active peltier cooled Canon 40D DSLR.

      Hello all,
       
      This is my latest image of the Eagle nebula (M16/NGC6611) in the constellation Serpens, this time imaged through narrowband filters using my 8" Celectron SCT, at F10 - 2032mm focal length, with my astromodded and active cooled Canon 40D DSLR.
      The second image is a cropped and rotated version to emphasize the famous "Pillars of Creation" part of the nebula, made popular by the HST image of the same name.
      The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal.
