Great image. As for color, software says it is the right color based on the instructions written by the programmer. And where did the programmer get THEIR decision process? Ah, who knows...

These two galaxies orbit each other with a separation of about 147,000 light years. These two galaxies are in Ursa Major. It seems most of the images on the web show this galaxy as blue, but Excalibrator says this is the right color. I am not sure why the other images are blue. Comments and suggestions are welcomed. http://www.azstarman.net/NGC3718.htm Bernard -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
