Basics of Market AstroPhysics is a 2 hour home video I made in 1991, back when I was using the pen name Hans Hannula. For a long time I sold it as a product. But the cost of copying and mailing video tapes made it a marginal product, so I discontinued it in early 2006.

However, it is a good discussion of Market AstroPhysics and is worth watching, now that Internet video technology permits electronic delivery. To play this video, you must have Windows Media Player or another player that can play .WMV files. You need a decent Internet connection, since the bit rate is about 180 KB. Internet Explorer works well. I do not know about other browers.
