Astronomical League's
Double Star Club

By finding, noting specific information, and drawing a simple sketch of the double stars (careful, some are triple or quadruple!) of the 100 listed objects, you can earn a certificate from the A.L.  The original list from A.L. does not include the SAO numbers necessary to make use of the LX200's GoTo capabilities. Be sure to use an official A.L. form to log your observations on--the following list is for your assistance in using the LX200's GoTo function.

You have to be a member of a club that belongs to the A.L. or join as a Member-at-Large.
