Mars with Dust Storm Receding

[The Thing]

My best attempt this season despite the shockingly low altitude of 13^o.

Hi Duncan

Interesting photo as I had a good visual look at Mars the other night with some family and (although as you say so low ~ those awkward trees) several of us noticed that it seemed to be a lighter red over one half that the other.  It might have been just the atmosphere but could be that the abating dust storm was the cause?

Nice pic by the way.

Good image Duncan, despite the elevation and dust storm.

Nice Duncan - Well done. John

Hi Hugh

If you look at the astronomy now website they have an applet that will show you Mars at a time and date. You can see what features are visible.

My image is showing all correct features, so I'm assuming that the residual dust is just blurring things a bit.
