Thanks to Emily's blog on the Hubble Legacy Archive (http://www.planetary.org/blog/article/00002408), I stayed up way too late last night downloading hubble data to process. Here's a great shot that hasn't been seen much. Processed using Maxim DL and Photoshop.

If it means you'll produce more lovely images like that, I'm sure there are a few of us here who'd happily chip in to buy you a huge jar of coffee to keep you awake the next few nights...!

It is a neat shot. I worked with it a while back. http://www.planetary.org/blog/article/00001828/

Nice Ted-
I meant to say the data hadn't been used in PR.

I was sad to see that Hubble sat out this time around.

I was wondering about that, and was going to email Jim Bell asking if that was the case...

I don't think Hubble was needed for good observations - according to many emails that I received, Mars was "going to be as big as the Full Moon as seen from Earth" for the first time in hundreds of years...

Here's my version of that shot:


Remember this was actually scheduled to record the impact that never happened - 2007 WD5.

I've posted a couple of other Mars views in my Flickr gallery, all of them processed by interpolating the wavelengths of each filter and running them through CIE XYZ color calculation code - no other messing around with channel balance and tweaks. Any slight color differences thus arise due to a different filter set. A couple of takeouts:


An animation of 11 frames showing Mars going through phases over a course of 1 Earth year.


In terms of color accuracy, this is probably the best available combination I've seen with Hubble. 4 filters - actual red, green and blue wavelengths plus an additional one in between red and green as an extra data point in interpolation where it visually matters the most.
