The Year In Space is a weekly online calendar that highlights space history, sky events, and astronomical milestones, pairing each entry with detailed write-ups and NASA imagery. Each week features a featured topic such as the discovery of Ceres or the Cassini mission, alongside a day-by-day calendar of notable birthdays, launches, and celestial events.

AutoStakkert! is free lucky imaging software created by Emil Kraaikamp for automatically analyzing, aligning, and stacking planetary and solar images captured through a telescope via high-speed video. The site offers downloads of multiple software versions (AS!2 through AS!4), sample images of Jupiter, Mars, and the Moon, and guides demonstrating how the stacking algorithm dramatically sharpens noisy astrophotography footage.

Al Kelly's dedicated astrophotography site showcases stunning CCD images of galaxies, nebulae, star clusters, and solar system objects captured with equipment including a Celestron CGE 1400 telescope and Orion Parsec 8300C camera. Beyond the image galleries, the site offers a CCD instruction manual, a G2V color calibration article, and links to fellow astrophotographers, making it a valuable resource for amateur astronomers interested in CCD imaging.
http://astrochemistry.eu/
Astrochemistry.eu, maintained by Guido W. Fuchs, serves as a collaborative hub for researchers in astrophysics and astrochemistry, covering observational, laboratory, and theoretical investigations of interstellar chemistry. Visitors can find featured news on prize-winning discoveries, upcoming conferences, job opportunities, and curated links to major databases, journals, and research networks worldwide.

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.
