Logitech Quickcam pro 4000 astrophotography

Date: 16 July 2003 Telescope: 10 inch SCT AVI: 1/10 sec for 120 seconds at 5 fps
Time: 01:12 (GMT + 2h00) Webcam: Logitech Quickcam Pro 4000 Processing: 100 and 150 frames stacked
Observatory: Hartbeespoort Magnification: 3x Tele Vue Barlow Software: K3CCDTools and Photoshop

Mars Apparent Diameter: 19.4 " Illuminated Fraction: 0.925 Distance from Earth: 0.4837 ua Central meridian: 345.71

Picture on the left: 100 frames stacked, picture on the right has 150 frames stacked. Adding too many frames includes lower quality frames which drags down quality. So even after 1500 frames have been captured, I use only 100 of the best frames, not 150 or more.
