These cards are currently available from Adirondack Video Astronomy . The program places the card in 640x480 black and white mode and allows capture as a video stream until memory has been filled or captures and examines each field for contrast as quickly as the computer can keep up. While the FlashBus is capable of near real-time contrast examination by the computer, the VideoPort is very slow. I'm trying to find a new card that will make laptops a viable option. The program is free.
Source code is included.
Because I like writing programs. Because while it works, others out there could improve upon it. No tape noise Capable of recording a series of fields to memory Capable of recording images that have the highest contrast in a field automatically. It is free and the full source comes with it. Images are always saved as Windows BMP format PCs are getting popular around the telescope.
