Double Star Club - 100 of the finest double & multiple stars in the heavens. al-dstar.pdf

DOUBLE STAR
CLUB

Rules and Regulations
Deep Sky List

by John Wagoner

American Association of Amateur Astronomers

The List

All objects are listed in Right Ascension order so that you can view them as they rise, and so that you can properly plan your observing sessions to make the most use of your time. Information provided on each object includes:a check box, object to be observed, Right Ascension, Declination, magnitudes of the component stars, separation, and position angle from the primary star in the double or multiple system. When listing the object to be observed, in order to simplify things, I have given the proper constellation name rather than use the traditional possessive form of the name. 

I realize that 100 objects out of many thousands in the heavens are only a small representation of what can be seen, and I have probably missed a few of your favorite doubles. If so, let me know which objects you recommend, and if there is enough interest, then just maybe we will have a second double star club. Until then, good luck, clear skies, and good observing.
