M57 "The Ring Nebula"

This 128 second picture is the compilation of 16 individual 8 second exposures. The Ring Nebula is a planetary nebula in Lyra.This image represents the first successful use of the "Track and Accumulate" function with Steward Observatory's CCD camera. Notice the hot blue central star, and the red outer layer. Red is the coolest region, blue the hottest.

M76 "The Little Dumbbell"

This is another Track and Accumulate image. M76 is a planetary nebula in Cassiopeia. This is a compilation of 20 fifteen second exposures. Unfortunatley the Track and Accumulate function makes the images somewhat "grainy", however, it was necessary to take a five minute exposure of M76 because it is the faintest of the 110 Messier objects at 11.6 magnitudes.

Saturn

This is a .3 second exposure. This is not a raw image as it has been sharpened twice and smoothed once. This processing was necessary to bring out the cloud bands.
