HI Azaelb and welcome to the forum. A webcam can indeed be used to image celestial objects though in the main its use is limited to solar system objects (moon and planets) and the very brightest deep sky objects such as Orion's belt (M42). The principle is to select the very best 'frames' from the webcam exposure and stack them on top of each other to create a final composite image. There is plenty of free software out there to help you select, stack and process the final image and a question over on the imaging section will provide a list of those that you can use. Unlike imaging deep sky objects (DSO's) such as galaxies and nebulae which essentially require a accurate tracking mount to help capture their faint light, a simple webcam can be relatively inexpensive and can be used on virtually any scope with it has tracking or not. Solar system objects in comparison to DSO are very bright and so do not reqquire lengthy exposure times to capture them. :smiley:

Clear skies and enjoy the forum

James
