Color Calibration of the Dark Nebula LDN673
This image has no good white reference because all the stars in the area have a strong warm color. Therefore, a set of short exposures of the nebulae complex and the face-on spiral galaxy were acquired to transfer the white calibration from the spiral galaxy to the master image of the nebula.
