Observing 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 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. In some cases I have not listed multiples that might require a telescope larger than a 60mm or more power than 150X to see. Stretch yourself! See what you can find! 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.
