This is very cool Roger. A few decades ago this was stuff of the Hale 200" now we amateurs can dial up a galaxy on our laptop computer GOTO it then whip off an image in a matter of minutes and have a knotted spiral galaxy appear on our screens. We can then print it off as a full gloss print and paste it onto our observatory wall before you can say "by Celestron or by LX200"...good times we live in Roger
