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.

PlanetQuest is a nonprofit citizen science project inviting the public to participate in real exoplanet detection research using distributed computing and a shared software platform called the Collaboratory. Visitors can download tools to search stellar light curves for transiting planets, contributing spare CPU cycles to a project affiliated with NASA's Kepler Mission.
