C

Description: A bit better color, more outer stars, and better background.

F

Description: One could play with this data for a long time.

G

Description: Some CN people actually liked C better than F, thought F was too pale.

I found C too cartoonish. This is in between.

H

Description: Still fiddling. How black/grey should the background be?

I

Description: In looking at others images, I thought I either hadn't captured well, or understretched (which was clearly the case). I think part of it was not wanting to burn out the core (and part was inadequate gradient reduction).

Comments are solicited on whether I should go back and try to lessen the core; or, does it look "natural"?
