Moon, Planets and more - WebCam Images Experiments |
I bought a Compro PS 39 WebCam in April 1999, which has a quite good resolution and what is very important: You can remove the lens and mount an adapter to 1-1/4". Additionally you may switch to a manual exposure mode and you may be able to expose up to 1/4 second.
It seems to be a good issue to use the non-interlaced mode of 240*320 pixels. I got the best results with this resolution sor far. But the 640*480 moon image is not bad either.
Some images here are in "stamp" size. By selecting the image you will get a higher resolution.
Best images are obtained in color-mode and 320*240 pixel resolution. I found out that all higher resolutions suffer from interlacing.
For image processing I do use the GIMP package (LINUX) with some plugins. Results are similar to "Photoshop" in Windows. A good program seems to be "Picture Window" especially for combining images.
Both the scopes, my Newton and the GvA Schiefspiegler have need to be adjusted very carefully again.
The images of MARS below are cropped from the original frame.
