Abstract

The article discusses the benefits and complexities of the charge-coupled devise (CCD) camera and provides tips on how to avoid residual bulk images (RBI) in astrophotography. It explains RBI as electronic charges made by the CCD that leaks back into the pixels and forms part of the exposure. It cites Kodak's KAF series as being prone to RBI. It lists factors that affect RBI including the uniformity of the crystal lattice, light penetration and the CCD's temperature. It states that the flood/flush/integrate protocol is the best method in handling RBI.
