After nearly 20 years of existence, this site is undergoing a complete re-do. Some features and software may be temporarily unavailable. Bear with me during this transition, please.
Sky Atlas 2000 page labels are now available for Southern as well as Northern Hemisphere objects. No more fumbling through pages at a star party to find the page you want! Click here for info.
Making donations for software you download is even easier! Choose between Paypal or the Amazon Honor System. Please support further development with a small contribution today!

The Caldwell Object Log is now available (without Sir Patrick Caldwell-Moore’s descriptions) in Mac and Windows application and Filemaker Pro formats, as well as the PDF format that’s been available for a while.
The Simple Observing Log version 2.0 is now available. The new version provides additional support for CCD astrophotographers.
The current version of The Ultimate Messier Object Log includes several much-requested features, including Night Vision (red) mode, on-line help, a sketch pad, astrophotograph entry screen, and a couple of bug fixes.
