[AZ-Observing] Re: Andrew Cooper's Mars Picture

Roger,

Tell Dean the scope was a Celestron Nexstar 11" operating at  f/20  (2x 
barlow, over 5.5m EFL) into a Philips ToUCam Pro.   460 frames stacked 
with Registax.  The seeing was reasonable but not great at Dean Salman's 
place off of south Wilmot.  The southern polar cap was usually always 
visible, but would pop in sharply every few frames.  The dust storm in 
Syria was easily visible in the live image as well at the dust spanning 
across Argyre.

Here is a second image I processed later in the day, I think the color 
balance is better, but still not sure, too orange? The northern polar 
cap was rather interesting, with a great deal of blue visible, not sure 
to make of it when processing the images.

I would like to get out and get a few more frames as these dust storm 
progress.
