... The Great Nebula in Carina . ... Eta Carinae , the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. Eta Carinae is the brightest star near the image center, just left of the Keyhole Nebula . While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Carina Nebula has been a veritable supernova factory . Tomorrow's picture: open space . ...

Most of these images were obtained by Mike Bessell, Michelle Buxton, Hwankyung Sung, Ralph Sutherland and Bob Watson at SSO using a 2Kx2K Site CCD behind a Nikon or Hasselblad lens or directly on the 1m telescope.

... The texture was formed in part by the bump map shown below. ... This is an example of how to render a realistic looking fabric, at fairly high detail. ... Bump maps are applied to a unit square. ... In my example I scaled this down to 0.17 (arbitrarily picked), which ammounts to 1/0.17 = 5.88 bump maps per unit, or 11.76 threads per unit. ... To match this to the bump map, it has to be scaled in half, so that we have two-by-two checker squares in each unit square, just like the bump map. ...
