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

The Caldwell Object Log
The Simple Observing Log
The Ultimate Messier Object Log
The Overlooked Object Log
The Eyepiece Calculator

Help keep my software free!

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 consider the following:

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! 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, click here.
