Few things are free in this world, but the software I've written for amateur astronomers is available "no strings attached."

Sky Atlas 2000 Page Labels
I've created a set of printable page labels for the Sky Atlas 2000 Second Edition (1998) by Wil Tirion and Roger W. Sinnott. This is simply an Acrobat PDF file you can print out onto adhesive mailing labels and stick on the backs of the pages of your spiral-bound Sky Atlas. (I have the Deluxe Edition. I am not 100% sure it will work with others.) No more searching in the dark for a page with a particular constellation or Messier object! Warning: I've only created the labels for the northern-hemisphere pages (1-23) and the Virgo galaxy cluster page, B1. (Lazy me....) If there is a high demand, I will add the other pages. The labels should work with any labels, such as Avery, that are laid out with 30 labels to an 8.5x11 page. You can also just print them out to plain paper and tape them in. PLEASE email if this is a helpful solution for you, as I will not be tracking downloads of this item! Click here to download. If you want the original Word file to edit or add the missing pages, email me.
UPDATE: The Caldwell Object Log is now available in application and database formats. (7/26/03)
The Simple Observing Log has been updated to support CCD camera information. (7/28/03)
The Mac downloads have been updated to OS X compatible disk images, and PDFs have been updated to Acrobat 6, for smaller downloads. (7/27/03)
I make my software available for free to the astronomical community: as a "favor." I know a lot of astronomers are young people with a small (or no) telescope, struggling to balance the expenses of life with this sometimes expensive hobby. However, if you are not one of those people, if you have dropped several thousand dollars on expensive telescopes, fancy eyepieces, astronomy-related travel, etc., please consider helping to defray the costs of creating this software. I have spent many hours creating this software, maintaining it (adding features and removing bugs), and keeping this site running. It costs me several hundred dollars a year. If you find this software helpful, if this site has saved you from having to spend time creating your own logs, if you are obsessive-compulsive about astronomy, and this software has made your life a little easier, please you consider the following:
Special Recommendation: I recently discovered the Web site for DarkAdapted (formerly Nightvision) software. This cool piece of software is cross-platform for Mac and Windows. It is also FREE! It changes the gamma settings for your monitor to preserve your dark adaptation (i.e., you can make your entire screen dark red), and is the perfect companion for people who want to run my logs on their laptops while observing.
