48 million stars?

[chris]

A paper describing how to use 'photometric parallax' to estimate the distances to 48 million stars from the Sloan Digital Sky Survey:

I haven't read it yet, but I imagine that this is similar to the methods Pascal Harmann used to produce the 2 million star database from the Tycho catalog.

Good, only 399,952 Billion to go.

I think 48 millions stars will only work with not so much slowdown,with Geforce 6800 GT/GS with 256 MB.It is useless for most of the users,I think.

Why, I know many users with 256 MB card memory. After all the price is not much higher. I have 256 MB, too, since 3 years. But don't worry, we won't have 48 Million stars in Celestia all that soon

If anyone read the text, the 48 million number is from only 5% of the sky, so if project in successful in the near future, we might have a catalog of the nearest billion stars.
