This is astonishingly good Bjorn - it deserves to be showcased on the main Cassini site.

Another one...

Colour composite with Lightness channel consisting of 10 stacked images:

That was certainly worth waiting for. Awesome GIF Gordan!

A Saturnian crescent...

This movie (using the CB2 and IRP90 filters) covers almost an entire Saturnian 'day', it would seem:

...and this one's for Mrs. ElkGroveDan.

You're more than welcome to use the image Justin. I think the best credit would be the one that Emily used on the Planetary Society blog:

Good luck with the newsletter.

Cheers,

Here's a quick rotation movie, using the CB2 and IRP0 filters:

Hi Ken,

Yes, please feel to use any of my images and animations in your talk - I'm only too glad to see them reach a wider audience!

Here is a rotated and slower version of the first animation:



Is this right speed, do you think? Are there any other adjustments you would like to see?

Ian.

Gordan,

Interesting indeed to read your account of assembling Cassini colour composites. With the mosaics that consist of two footprints only, my approach has always been to carefully align and join the Green raw images first, and then to use that as a geometric template for aligning the Red and Blue channels.

All of these images use RGB - I haven't actually tried the Violet filter yet, and probably wouldn't anyway, unless the Blue image was missing or corrupt. In any case, the colour adjustments you and Dilo have applied to the mosaics look great!

Cheers.

Oooh, very pretty indeed dilo!

Here's my composite, with colour adjustment based on Gordan's earlier advice:

Had to improvise a little bit with this one, as there seems to be a Red frame missing, somewhere:

I do plan to go back and adjust the colour balance of these images at some point, so thanks for the pointer Gordon. Unfortunately, the stretching that is applied to these raw JPEGs means that two views that should have identical contrast, hue and saturation, end up all over the place.

What do you suggest is the best way to correct the colour in these images? Should I manually adjust the brightness and contrast of the B&W raws, or should I simply change the Red/Green/Blue values of the resultant composite?

Cheers,

Ian.

A new set of colour images, with some nice views of the shaded side of the rings:

You're welcome James!

Here's a short GIF animation showing Cassini approaching the ring plane from below. Note how several atmospheric features can be seen moving from West to East during the sequence:

Ian.

Thanks nprev - I'm really flattered by your very kind words! I'm having a great deal of fun with the Cassini imagery at the moment, as you can no doubt see.

Ever since I first discovered this website, I have wondered and marvelled at the fantastic work done by the other members here - it's amazing to see so much talent in a single forum. It's very rewarding for me to finally be able to give a little bit back to the community that has provided me with so many truly great images over the past 18 months or so.

I think this must be my favourite view yet:

Is the Von Karman auditorium Voyager spacecraft really a mockup? I was always under the impression that it was Voyager 3.

Thanks Emily. I sure the colour balance isn't correct, and that Bjorn or ugordon could do a better job in that respect, but despite that, I'm quite pleased with the results so far.

My latest composite is a natural colour view of the south pole:



Cheers!

Ian.

One more for the road...
