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.
