|The Mars opposition of 2003. Photographs were taken with a 3com WebConnect webcam (at medium resolution) at the prime focus of my f/15 7" LX-50 Meade Maksutov-Cassegrain Telescope. All photos are at f/15 unless otherwise stated. All of these images were stacked using Registax 2.0. Since the atmosphere refracts the Red, Green, and Blue channels by differing amounts, the color shift option was used to compensate for this effect. Wavelets were used to increase the sharpness. The files so created were then further processed with Corel Photopaint 9 using the unsharp mask, tone curve, hue, Gaussian blur and contrast. All of these are eyeballed for best iamge.|

polar cap's details.
Right: Time: 8/23/2003 12:05 am PST Blended the polar-optimized photo and the surface-features-optimized photo to get the best of each.
|All of the pictures above were processed from the same video file. This shows the kinds of effects that processing can have on enhancing features on a planetary photograph.|
