Does any have the book 2008 Sokkia Celestial Observation Handbook and Ephemeris mentioned in the article? I tried to download it using the link provided on their web site, but the URL (http://www.rollanet.org/~eksi/2008%20Ephem.pdf) is bad, as is their contact URL. ▼

The '%20' in the URL resolves to a space, which just doesn't work IIRC. I found my way here: http://www.rollanet.org/~eksi/Handbook.htm but the link to the PDF is encoded the same way there. There is a "contacts" link on that page. ▼

Oh, and the 'contacts' link on the page I posted ... it works if you alter the initial 'C' in 'Contact.htm' to a lower case 'c': http://www.rollanet.org/~eksi/contact.htm Sloppy HTMLing, to be sure. |
