Welcome Friends and Participants,
This database contains all resolution reports on file for the Sissy Haas project, "Finding the Limit for Uneven Double Stars." The project began in September 2012 and is now in its fifth year. As of February 18, 2017, ninety-two observers have logged 2,517 observations of fifty-five target stars, using fifty-five different apertures. If you would like to become a contributing observer, please register by contacting: Sissy Haas.
Update No. 118 completed 2017:02:19:01:40 UT. Four reports were added on two targets. See Recent Entries page. Gamma Caeli has been changed to tentative with 80 mm aperture. More observations requested. See the Summary page.

Navigating the Database:
- Master Table – Displays the target stars with separation in arc seconds along the y axis, and magnitude difference (ΔM) along the x axis. Each star name in the table is an active link. Clicking on the star name will display a list of all resolution reports on file for that pair, by aperture.
- Recent Entries – Highlights the latest resolution reports added to the Database. We update the database every two weeks.
- Data For The Test Pairs – Lists coordinates and supporting data necessary for locating and observing the Test Pairs. Standard Atlas Map Pages and SAO Numbers are included.
- WDS Reference – These tables list data on the test pairs extracted from the Washington Double Star Catalog. The targets are listed in order of Right Ascension.
- Summary This is a new page which displays the probable minimum aperture need for each test pair, based on data reduction of the last four years of observations. It also indicates which pairs require more observations.
- Community – A list of our participants, location, equipment and respective Astronomical Societies.
