Web Cam Astrophotography Basics
Web cams have changed amateur astrophotography profoundly. You
can now have a CCD for a fraction of the cost. Web cams can take awesome planetary and lunar astrophotos right out of the box. You can use the capture software that comes with the cam for capturing your shots and then use freeware to process the results. Can’t get much cheaper than that. Of course for better results it is you should use specialized software, but that is available on the cheap as well.
And if you are a do-it-yourselfer, web cams can also be adapted to take long exposure astrophotos, pretty cool right? Plus there are ready to go, web cam based planetary imagers now available from Celestron, Meade and, Orion. Meade and Orion also have imagers for long exposure, deep-sky imaging. All these include software. They are however more expensive.
