I have been interested in astronomy since the 1960's.  My main instruments are the two eyes I was blessed with.  In 2001, I augmented them with two telescopes:  a 4" Refractor, and a 7" Maksutov-Cassegrain.  Though I enjoy observing all phenomenon of the night sky, I have developed a particular interested in the study of binary star and double star systems.

The Haas Project:

In the September, 2012 issue of Sky & Telescope, noted double star observer Sissy Haas requested volunteers to observe and compile data.  The purpose was to statistically prove how much aperture is required to resolve double stars of unequal brightness.  Entering it's sixth year, the Haas project involves ninety-five observers from all over the world.

As an active participant, I've observed 89 of 109 potential targets.  Additionally, I've created and maintained the project's online database.  Presently, it contains over 2,500 observations of fifty-five targets stars.  The database is organized as a sub-section of this website;

Two of my binary star renderings were published in the September, 2016 issue of Sky & Telescope, (p. 31).
