Clark M. Thomas offers a detailed analysis of comet imaging techniques, comparing amateur astrophotographer Damian Peach's stunning wide-field ISON image against the professional Subaru telescope's shot of Comet Lovejoy. The article makes a compelling case for tracking background stars rather than the comet itself, arguing that the resulting sharp stellar fields and visible deep-sky objects produce the most visually rewarding comet photographs.
