Crab Nebula With Corrections

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. Click on the photo for the full sized image and then right click to view the image only and zoom (or download with the disk icon) to see the removal of the hot pixels.
