Stephen Saber's Concordiem Borealis is a carefully curated observing list of 400+ deep sky objects and double stars for northern hemisphere astronomers, unifying targets from the Astronomical League's Messier, Caldwell, Bino Deepsky, and Double Star programs with the RASC's Finest NGC Objects. Organized by constellation with magnitude, coordinates, and Pocket Sky Atlas chart references, it serves as a practical field companion for observers working through official observing programs.

Created by Ronald J. Maddalena of the National Radio Astronomy Observatory, this interactive tour guides visitors through the Orion constellation using five images captured at different wavelengths including optical, infrared, and radio. Visitors can explore astronomical objects in Orion, learn the mythology behind the hunter, take a glossary-supported test, and see how the same region of sky looks dramatically different depending on the telescope used.
