Somehow I ended up looking at <a href="http://hubblesite.org/newscenter/archive/releases/1997/38/image/d/" rel="nofollow"> this version of NGC 6826</a> in which the red channel was badly blown out and I also wondered if I could pick and arrange the different filters available to not end up with a lime green nebula. <a href="http://chandra.harvard.edu/photo/2012/pne/ngc6826.jpg" rel="nofollow">Yet another version</a>, done for Chandra so we can see the x-rays emitting from the nebula, seemed awfully grainy and had a sharpening halo around the center of the nebula.

Inspired by these two, I have created my own version. Also, since the data was readily available, I did my own <a href="http://www.geckzilla.com/astro/NGC6826_w_xray.png" rel="nofollow">x-ray version</a> too.
