Use any webcam to make time-lapse, motion-detect, meteor trail planetary or animation movies. Easy to use! Simply start HandyAvi then select the type of movie you want to make (Time-lapse, Motion-detect, meteor trail, Astronomy or Animation). Then use the control panel that comes up to set up and begin making your AVI movie.
SCIENCE: Time-lapse movies let you speed things up such as flowers opening up or clouds moving in the sky. Examples on http://www.azcendant.com. Time-lapse cameras used to be extremely expensive. Now you can make time-lapse movies inexpensively using a Webcam.
SECURITY AND SURVEILLANCE: Motion-detect movies let you leave out boring stuff. For example, you could point the webcam at your yard and instead of getting a really LONG movie showing your unchanging yard, you'd get a much shorter movie showing only the things that HAPPENED in your yard, such as a person, dog or cat walking through. If you were to point the camera at a bird feeder, the movie would only show the scenes where birds were present and moving about.
ASTRONOMY: You would usually take these types of movies through a telescope. Most webcams are sensitive enough to allow you to make images of the moon, Venus, Mars, Jupiter, and Saturn. There are user settings that allow you to take, for example, 100 frames every 10 minutes. This is handy for making movies of Mars, Jupiter or Saturn as they rotate.
METEOR TRAILS: Capture entire meteor trails. Capture lightening bolts too.
ANIMATION: Create your own animated movies.
MEADE TELESCOPE CONTROLS: HandyAvi contains a full set of Meade telescope controls so that both the webcam and the telescope can be controlled remotely. Automatic planet centering system
MOVIE VIEWING: An AVI movie viewer is built-in with continuous or frame-by-frame viewing features.
MOVIE EDITING: Movie editing features are built-in. Select frames, crop frames, make new movies from the original.
UPLOAD: Movies to your web site.

Does astronomy intrigued you? Do you often look into the sky at night and marvel at the wonderous reaches of space?The moon is the closest celestial object to us. But did you know that the same side of the moon always faces the earth no matter where the moon is in the sky or what phase the moon is in. The back side of the moon is never seen from the earth. And that is referred to as the dark side of the moon. But the dark side of the moon is not always dark. The sun could be shining on it, but we cannot see it because that side of the moon is never in view from earth.If you have an interest in astronomy or lunar events, Moon Glimmer will enable you to monitor the lunar phases without stepping outside.
