Comet Ikeya-Seki, October 1965. Photo RDP, from College Station, TX.

Look for comet C/2012 S1 (ISON) in November/December 2013. Could equal Ikeya-Seki!

Hubble Space Telescope "album" of images

Hubble Galaxy Collection

Star formation region in M16, the "Eagle Nebula" in Serpens.

Hubble Space Telescope photo of distant galaxies. Click on image.

Ultra Deep Field image from HST 11.3 day HST image.

Sloan Digital Sky Survey. Go to "Visual Tools," Finding chart", and put in the following parameters: ra: 185, dec: 5.5, 2"/pix, width: 1024, height: 1024, then click "get image." Scroll around. This is in the Virgo cluster of galaxies. Then try other values, espcially near dec=0 to 15 deg and ra=120 to 240 deg (8h to 16h). After going to Finding Chart, try "Navigate," first zooming down to get a large field. Another Virgo field: ra=187.5, dec=13.0, containing M87; or 187.5, 12.4.
