DOUBLE STARS INDEX -
Below are the steps to measure the double star separation (rho) and position angle (theta) using AIP4WIN software with a alt-azimuth Dob and Canon EOS T2i DSLR camera.
The following list of items are needed to use AIP4WIN for measuring the double star separation (rho) and position angle (theta).
USNO-A2.0 Catalog Directory
The first step is to configure AIP4WIN by setting the USNO-A2.0 catalog directory using the Select Default Directory Locations for Databases. As shown below the USNO-A2.0 catalog directory is C:\USNO-A2.0.

David Haworth enjoys astronomy imaging and processing those images to bring out details that cannot be seen easily by visual observing with the same size optics. David Haworth started astroimaging with a Cookbook CCD camera he built in 1996 and since then has used many types of cameras to image the sky. David wrote Chapter 2: "Afocal Photography with Digital Cameras" in the second edition of "The Art and Science of CCD Astronomy" which was published in December 2005. David's images have appeared in magazine front covers, articles, books, catalogs, videos, music CD covers, T-shirts, other web sites, etc.
