Messier Catalog - M74

Constellation: Pisces

October 05, 2003.
The M74 image was made from 140x45sec, Vesta SC3 B/W. In addition to dark frame subtraction, I had to apply an artificial flat field to remove what appeared to be amp glow, even though the exposure was done with AMP_OFF. The glow effect is still visible, but the flat-field treatment improved it.
