Image of the face-on spiral M101 in Virgo. The image was taken on May 4th 1998 and is the superposition of two images to give a total exposure time of 90 seconds. The images were dark subtracted and flat fielded. 222KB.
A color image of the spiral galaxy M74, taken on December 29th, 1999, using 3 color filiters with 5 minutes exposure times for each filter. The color filters used are Harris B for blue, Harris V for green and Harris R for red. 196KB.
M66 is a barred spiral galaxy in the constellation of Leo. This color image was taken during the evening of April 8th, 2000, and is a combination of separate exposures taken with the Harris B, V and R filters. Each filter "exposure" was constructed from thirty 20 second exposure frames or the equivalent of 10 minutes per filter. 20KB.
This color image of M51, the Whirlpool Galaxy, was taken the evening of April 29, 2000 by Greg Guzik and Mark Solvak using the Apogee AP7b CCD camera. The color representation was obtained by combining images taken with the Harris R (for red), Harris V (for green) and Harris B (for blue) filters. Each filter exposure was also constructed from 20 individual frames of 30 second exposure each. Thus, the effective exposure was 10 minutes for each filter. All frames were dark subtracted and flat fielded before being combined. 166KB.
