These are free downloadable resources for amateur astronomers. If you would like to see something here that is not listed, please leave a comment. In keeping with my No Ads policy, I will only link to it if it is absolutely free (not nagware, not shareware, not upgradeware) and easily downloadable. For software, I would prefer it be available in a variety of platforms.
- Toshimi Taki’s Mag 6 Atlas: 12 pages, formatted for A3 paper, but works fine on US Letter.
- Toshimi Taki’s Mag 8.5 Atlas: This one is huge. It is comparable to high-end bound atlases you would spend a couple hundred dollars on. You will need close to a ream of paper to print it out single-sided. There are 146 main pages, three detail pages, a manual, and a slew of indexes.
- Johnson’s Mag 7 Atlas: This atlas is a nice intermediate between the two atlases above. It suffered from a lack of indexes, which I correct below.
- Jan Tosovsky’s planisphere software : This download allows you to view the planisphere on your computer, or print out a cut-out kit to make your own.
- Toshimi Taki’s double-sided Planisphere
- Uncle Al’s Kepler Star Wheel
- Uncle Al’s StarWheel (without the Kepler plots)
