All these pictures were taken at prime focus with a 10 inch Meade LX200 GPS telescope and a cooled Logitech Quickcam Pro 4000.
This is what I call a 'quick and dirty' webcam experiments webpage.
These are my first images of Jupiter using my cheap wedge. I only did a rough polar alignment before taking these images.
First evening of imaging Jupiter with wedge installed, polar aligned, peltier cooling running and most serious vibrations fixed.
Results show most detail so far. So now that I managed to capture detail, my next step is to spend time experimenting with processing to make the pictures prettier. ( You can see detail in the pictures, but some pictures of Jupiter are quite ugly. )
All pics done with fan at 9 Volt and Peltier switched on

Now that I have the wedge I can make rotation movies. However my pictures of Jupiter are too noisy at the moment in order to make a nice movie.
Unfortunately there were darker surface feature on Jupiter (at the top and to the shadow's left) just behind the shadow transit - so the shadow is not perfectly round.

The bottom row represents my most detailed webcam pictures of Jupiter yet.
I am happy with the amount of detail shown, however the pictures are too noisy. The color is also ugly.
My next priority is therefore experimenting with different processing options.
All these images were captured at prime focus. Tonight I start using my 2x Meade Barlow lens.
