Following is a list of the pages on this site containing downloads:

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 historical marker was installed by the Delaware Public Archives on November 20, 2015.  It was sponsored by Delaware Senator Ernesto Lopez and the Lewes Historical Society.  The analysis to locate the site was performed by Geoffrey Thurston and James Morrison.

Due to the death of James E. Morrison we are unable to accept any orders, make astrolabes or respond to correspondence.

If you find any contact information on this website, it is an oversight and not a "back door". Please DO NOT attempt to contact us by any means. We are very sorry, but this was a one-man operation that has now ended.

Unfortunately, any unfulfilled orders will not be completed and all correspondence will be unacknowledged.

We are sincerely sorry and we apologize for any inconvenience.

We have accomplished our purpose if these few pages have satisfied or increased your curiosity about astrolabes.  We are no longer able to offer The Personal Astrolabe. Please see the note above or on the home page.

We still offer 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. No support assistance is available. If you need help, try an Internet search and you might find something useful. We honestly don't know what you'll find. Our best tip is to run the program in the DOSBox program. You can get more detailed informtaion at the link above.

In the unlikely event that anyone cares, here is a picture of the author giving an astrolabe tutorial to an eager young student.
