What is WebcamÂ Astrophotography?
Webcam astrophotography is a method to use relatively cheap webcams to take photos of the planets and the moon. A few years ago this would have had to be done with expensive CCD cameras, now with some freely available programs on the web and a proper webcam, amateurs can get some very good results. Although a good CCD camera will still produce better images, using a webcam is a nice easy way to get introduced to astrophotography.
What we do with the webcam is essentially capture a video of the target i.e. Moon / Jupiter etc. We then import that video into a stacking program which allows us to split it into individual frames, remove the bad ones and combine the good ones to get our image.
