The latest Cassini portrait of Saturn:
I put this together on my laptop, so there may well be color/brightness issues! -------------------- |

That's beautiful, Ian!

Not having any of the fancy tools you all have, I don't frequently contribute much in the way of colour images. But I've recently taken a stab at writing a programme to merge multiple colour filtered images into a single image. Here's my first results. Probably some alignment issues to work out. Sorry if this seems overly ameturish, but I was pretty excited about it at least.

The merge looks nice but as you can see there are some color bands probably due to the individual RGB frames not quite overlapping with each other (as the spacecraft moved in between). So probably better to register those RGB frames (by hand?) first to create individual color images, and then merge all those color images.
But I know it is not that easy (as the viewpoint changes too), and for sure I wish I had the time to do these things, so meanwhile I just admire the work of everybody else who creates these wonderful mosaics! Airbag |

I gave it some manual pixel offset options and corrected the orientation. Looks much better now, I think.

Some new Titan images are down.
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=267957 http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=267951 The colours for me keep coming washed out. Is the colour contribution from the images a linear function of the pixel brightness?

Your colours look good to me, maybe a little understated but not much. We have to shed the Voyager orange orb idea. Think manila envelope.

Nice image of the ringmaker moon by Saturnshine: http://saturn.jpl.nasa.gov/multimedia/imag...5/W00075616.jpg
EDIT: What makes the diagonal bright smudge - stray light? |
