This tool reprograms some feature of the webcam to drastically improve the picture quality. There is a nice tutorial (sorry only in German here: Attached are three snapshots of the picture-quality before the tuning, after the tuning and one after recoloring with another great freeware-tool: aviRAW. With this tool you can automatically recolor the B/W-pics of the improved webcam. The gaining of sharpness and detail is extraordinary. I cant wait to try it on the night-sky. photo

There is included a live-histogram and reticle as well as the possibility to attach the guiding-system from some platforms. You find the link to the software here: . For usage with every capture-software there is another brilliant freeware tool: WcCtrl. With this tool you can control your webcam (regardless of your capture-software) and save different settings (one for moon, one for jupiter etc.) so you can use them every night. You find the software here: . Again I am not sure if already someone posted this links. These tools are awesome and will definitely help to improve the quality of my astrophotos.

One addition to the webcam improvement.
I found out that AviRAW was not able to recolor the RAW-avi if

a) the fps-settings are higher than 15 fps
b) with any other resolution than 640x480.

I guess in both cases the video-signal is compressed too much. You gain
just a b/w-picure without any additional sharpness.

So from my experience I suggest to always use the 640x480-resolution
(even if that means bigger avi-files) and stay at 5 fps.

That means you only get 1200 picture from a 4 min avi-file (on planets
like jupiter it is not recommended to record avi-files longer than 4
minutes due to the rotation).

Hope that helped.
