Graticle and CCD Observations of Faint Wide Pairs

There is no doubt that there are large numbers of relatively wide and faint systems for which little astrometry and photometry exists. The USNO have recently published on their website a list of more than 6000 pairs which have yet to be confirmed as doubles or which have been unduly neglected. These pairs are all wider than 3'' and are relatively faint but could be observed satisfactorily with a medium aperture and a graticule micrometer - see Chapter 12 and the work by Harshaw.1 These stars would also be ideally suited to CCD astrome-try even with a moderate telescope and a commercially available CCD camera. Chapter 16, written by Doug West, indicates how this can be achieved. The list of neglected pairs can also be found on the CD-ROM.
