Following is a list of the pages on this site containing downloads:
- The Electric Astrolabe is a planetarium program in the form of a planispheric astrolabe. You can download the program and documention.
- A PDF of a chapter from the author's book, The Astrolabe, can be downloaded from this page.
- A description of The Personal Astrolabe and ordering instructions is available on this page.
- A template for making a Mariner's Astrolabe is available.
- Although it has nothing to do with astrolabes, you can download a paper describing the American Philosophical Society expedition to Lewes, DE to observe the 1769 transit of Venus. This interesting footnote to the history of Venus transit observations is an excellent example of state-of-the-art colonial surveying and practical astronomy. This paper is the first attempt to document the Lewes expedition in detail.
This site is a complete redesign of the astrolabe web site that has been in operation since 1996. There may be a few migration details to attend to, particularly when your entry to the site is from a search. Please let us know about any problems you have or any suggestions on how the site can be improved.
We have accomplished our purpose if these few pages have satisfied or increased your curiosity about astrolabes. We offer an inexpensive astrolabe reproduction called The Personal Astrolabe in an effort to make astrolabe information more accessible. Even though there is a modest charge for The Personal Astrolabe it is not really a commercial product since it is offered at cost. If you would like to know more about astrolabes, would like to own your own astrolabe or learn more about The Personal Astrolabe, send your mailing address to Janus at the address below or via e-mail to receive free information.
We are now offering a free download of a planetarium program in the form of a planispheric astrolabe called The Electric Astrolabe. Click on the name for a description and download and installation instructions.
Please drop us a note to let us know what you think of these pages, why you visited, how you found them, whether your needs were satisfied or just to say hello. We can handle notes in German, French or English, simple Italian and British (if the constructions are kept simple). We answer every single message we receive that asks a question. If you do not get an answer, try again and double check that your e-mail address is correct, or send us your mailing address to receive information about the Personal Astrolabe.
