On this site I want to introduce my photographic doublestar project. As a start I selected the brightest and wide seperated double and multiple stars from the WDS (The Washington Double Star Catalog http://ad.usno.navy.mil/wds/). Because of my small scope the selection criterias were as follows:
    Dec north of -30, Mag1 brighter 6m0, Mag2 brighter 9m0, separation more than 15"
    together with some prominent exceptions
I took the images between Oct. 2005 and Sep. 2006 in Vienna/Austria with a Takahashi FSQ (APO 106/530), 2x Barlow, CCD Starlight SXV-H9 and Vixen GP-DX without guiding. The images are made with RGB-filters, each 2x 10 sec. and all identically processed. The photos on this webpage are details of the originals. The limiting magnitude is about 13 mag.
The constellation photos were taken with a Canon EOS 10D and 28 mm lens and have been reduced to 1/3 and have therefore - as the doublestar photos - identical scale and also N-S/E-W orientation is always correct.
Astro-friend Wolfgang Vollmann will do astrometric measurements with the photos. We will publish the results here later, until then you can find the infos and more on Wolfgangs homepage: http://home.pages.at/vollmann/.
Phase 2 of the project will start soon with bigger optics.

The following list is sorted by constellation (alphabetically by the latin abbreviation) and RA of the doublestarcoordinates.
