Thanks Kadri...mis-shaped moons has happened to me on more than one occasion and now I know what to look for...thanks so much!
Elipsis1...the background is available here, its "starfield background" by moodflow. The clip file is a few years old but, should be easy to find in the file sharing area...its a great addition to any space or night image...the stars and nebula are easy to manipulate. Shame on me for not giving credit to moodflow and the others who made the plants.
Thanks for the suggestions and comments!
