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.

Bob Riddle's 'Qué tal in the Current Skies' is a long-running amateur astronomy site that began in the late 1980s as posts to the Big Sky Telegraph BBS and evolved over 30+ years into a web resource covering Earth and Space topics. The site now serves as a transitional landing page pointing visitors to his continuing work on Substack, with archived daytime and nighttime sky photos, calendar data, and astronomical observations.
