Collection of SN1987A Pictures (SINS) 300 dpi versions

I created these images from the Digital Sky Survey. Each image covers ~3x3 degrees and are ~5000x5000 pixels in size. When printed @ 72 dpi, each image can be 6 feet across.

Pete's own CCD images taken with FLWO 1.2m and CTIO 1.5m

various Sn 1987A pictures and High-Z redshift supernovae. Cool galaxys recently "discovered" in recent supernovae searches. (not quite ready for prime time... so the link is to the above page )
