For the 1st time: Planet Mars webcam astrophoto

This is the 1st time I tried to photograph a planet. In this case Mars. It is standing very close to Earth now. I made this picture using a Philips ToUcam webcam PCVC740K ("the egg") which I bought almost 7 years ago when webcamming was a hype. I never knew back then that this particular webcam is one of the most sought-after and suitable ones for astrophotography. This Philips webcam has a CCD sensor (and not a CMOS, like with many other webcams nowadays, which is 10x less light-sensitive). I put this webcam on my 200mm newton telescope with 1000mm focal length. By using a so-called 2x "barlow" (teleconvertor) I doubled the focal length to 2000mm. I made a 4 minute .AVI movie with 10fps, 1/250 shutter and the gain on 25%.
This particular picture of Mars is a composition of 34 images from a 4 minute AVI movie I made (so 34 good pictures out of 2400). The reason only 34 images were good is mainly caused by many turbulence in the atmosphere. I stacked the good pictures using registax (free software) and post-processed with Photoshop. The result is not bad for the 1st time. The small circle on the top is the Hellas region, the black line pointing down is Syrtis major.
