The IRAS PSCz catalog (InfraRed Astronomy Satellite Point Source Catalog) includes more than 15,000 galaxies all over the sky, unlike the 2dF and SDSS projects, which have examined only limited regions of the sky.

This Addon provides a color-coded CMOD model of the PSCz catalog, with a different color for each of 235 clusters of galaxies. Some large-scale structures are visible.

Now THIS is more like what I would expect to see from a "sky survey"!

Nicely done Selden. Better than the "butterfly wing" data display from SDSS.

As usual, I had to lower radius for my ATI card.
