I have no experience with video cameras, other than web cams. The
idea of taking hundreds or thousands of short exposures and then
stacking the best was a revolutionary idea that produced remarkable
planetary and lunar images.
With the introduction of the Meade DSI series and the AutoStar Suite
software things got upped a couple of notches. While the DSI series
cannot take images at the rate of a video camera, they can take
multiple short exposures (down to a micro second) for
stacking/combining.
What is really remarkable is the ability to automatically reject bad
images and only stack ones that meet an acceptable criteria. You can
also draw one or two (for de-rotating with an Alt Az mount) tracking
boxes so you can align the images perfectly. What this means is you
can set up, start taking images and even with a poorly align mount,
come back in 30 minutes or an hour and have an amazing image waiting
for you. While the documentation for the AutoStar Suite is much less
than desired, the software is really amazing and extremely powerful
considering it is included with equipment. The recent DSI and DSI pro
price reductions made this technology available for a around $100.

Hello, everyone,
Bill McDonald, president of the Prescott club, joined us at Cherry
last weekend with his Mallincam color video camera. Many of us took a
look at the results (essentially real-time color images on a 13" TV
monitor) and were impressed. Here's some additional info from Bill:
