This post shows the results of our first tentative imaging Mars close to its oposition.
On November 7th, 2007, Leo and me were at Satan Hill in ESAC to try to image mars with the Leo's a Dobsonian 65 cm telescope. The following images show our best results with the Toucam Pro webcam, blocking and pass NIR filters and a 3x Barlow. The captured video tracks were stacked with REGISTAX and the histograms modified to show the best contrast.
The following image was captured around 1:30 GMT with the NIR blocking filter.

The next one was captured around 1:30 GMT with the NIR pass filter.
A combination of both images substituting the red channel of the firs image with the second one produces the next image.
The planet disk shows a well defined phase yet and both the RGB and NIR images show very well different details of the surface. The image is centered in Chryse planitia with Syrtis Major appearing in the terminator. In the north cap, the usual winter CO2 froze can be clearly observed far from the polar regions.
