10000 frames each captured in SharpCap, aligned in PIPP, best 1000 frames stacked in Autostakkert.
Colour image RGB aligned in Registax then combined with IR image and wavelet, contrast and saturation adjusted.
The seeing was poor and Mars elevation only 10 deg, despite this some interesting detail appearing, the Hellas crater seems brighter than surrounding regions in both images.

In late June, 2001, the Hubble Telescope revealed the first stirrings of a dust storm in a small region of the Hellas Basin on Mars. For several days the storm alternately grew, then retreated. Then it exploded and quickly boiled out of the Hellas Basin, spreading both north and east. Within a few weeks it had covered the whole planet, as seen below.
