Saturn last night

EDIT 20-05-2014:

I just did some post processing work and this is what I could get out of the 2500 Mars frames I had:

Although the image is still of fairly poor quality, I guess I like it. You would too, if you consider that this is what one of the better frames looked like:

Last night I imaged Saturn using my modified xbox webcam. This time I didn’t use my barlow as I found it significantly reduced the quality of the image. I guess that’s what you get for 25 euros. Also, as adviced by many on stargazerslounge.com, I took a lot of videos to get a total of about 3000 frames. Of these I stacked the best 1000 in AutoStakkert!2, used wavelets in Registax v6 and did some post processing in CS6. One thing I noticed the last time I imaged with my xbox camera, is that the red image is over illuminated and even blurry. This is probably due to the infrared filter I removed. So I guess I should put an IR/UV-cut filter on my wish list (which is quite full of astrophotography stuff 😉 ). Final Saturn picture is below. I also took thousands of frames of Mars and I will process these later.

Saturn from last night, stacked, RGB aligned, applied wavelets, adjusted contrast and used smart sharpening.

I re-processed Saturn after I flipped it to get its correct position: seen from above. (The setup I have gives an upside down view on camera) I think the position of Saturn with respect to its rings is better visible in this image.
