I was struck by how much images like this...
http://saturn.jpl.nasa.gov/multimedia/imag...5/N00148493.jpg ... remind me of the view through my 4.5" scope when I peer into it without the eyepiece. LOts of fascinating internal light reflections there... -------------------- |

ROFLMAO, thank you for also posting the WAC view. I just about had a heart attack when I saw the NAC image.

Awesome Prometheus images, a quick RGB composite from the first set: Very nice. I was wondering what you're basing your color balance on. I did an RGB combine after cleanup and alignment in MaxIm DL5, and I end up with slightly more color variance across the little icy rock. My version also uses a touch of non-linear stretching so that the bright regions are easier to see. Upsampled and slightly deconvolved (0.5 PSF, 4 iterations). Sean W. |
