Crab Nebula With Corrections

This is a stack of 9 frames of ten-minute exposures with the gain set to about 3/4 of maximum. New darks and bias frames were captured at this setting and the flats taken for the previous low gain setting were all applied and stacked in DSS, and a basic non-linear stretch was performed in Photoshop. The estimated color corrections applied previously in DSS were removed.
