| Notes | This color image is made up of over 35 hours of data mapped
to traditional RGB colors. Ha is mapped to Red, OIII is mapped to
both Green and Blue and the SII data is mapped
Red. The LRGB data is used for
the background and star color. The Ha signal dominates the nebula but the right side detail was very feint even after 13 hours of exposure. In this image the data is pushed fairly hard to show the full structure of the nebula.  |
