Thanks Patrick. I rotated the color data almost 90 degrees to get it to align with the luminance data. The result is no star color on the edges of the image. It is funny how the brain (my brain at least) hardly notices that the image is basically black and white at the left and right margins. The color in the galaxy and a few close stars is enough, and the brain sort of fills in the rest. Thanks for taking time to comment. Congrats again on the great GRB data.

Another fine effort. And despite your cautioning about the colors somehow not being aligned I don't see anything amiss. Really does look nice.

Hi All. I just posted a new galaxy image to my website. It shows the Splinter Galaxy, or Knife-Edge Galaxy, NGC 5907. I shot the image over two nights, separated by a week or so. Between sessions, I rotated my camera and forgot to rotate it back... DOH!! As such, the color data does not match the orientation of the luminance data, but it doesn't detract too much from the image. I collected the color data last night, with a full moon and a gusty wind, so it was a challenge to process, but it turned out pretty good. I finally feel that the scope is completely dialed in and everything is working beautifully.
[Description from Wikipedia] NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth. It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars. It is a member of the NGC 5866 Group. NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. Then in 2006, an international team of astronomers announced the presence of an extended tidal stream surrounding the galaxy that challenges this picture and suggests the gravitational perturbations induced by the stream progenitor may be the cause for the warp. NGC 5907 is also known at the Knife Edge or Splinter galaxy. The galaxy was discovered in 1788 by William Herschel. Supernova 1940A was in this galaxy.
