You can create afocal images by placing your camera over the eyepieces of a telescope. In this way, the camera creates a lasting image of what would otherwise be a fleeting observation. Afocal photography is what allows astronomers to share the telescope's projections. 

If you don't have a telescope, you should come to one of the ASN's monthly star parties where members who own telescopes are egar to share them with others.
