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.
