| Venus near greatest elongation in 2004. 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. 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. |
