Measurements of 208 Aitken Visual Binary Stars with a 280 mm Reflector
Abstract
This paper presents the measurements of 208 visual binary stars discovered by R.G. Aitken and listed in the WDS catalog. These measurements were obtained between November 2016 and January 2017 with an 11" reflector telescope and an ASI 290MM CMOS-based camera. Binaries with a secondary component up to magnitude 15 and separation between 0.6 and 5 arcsec have been measured. Measurements were carried out on auto-correlograms computed on sequences of a thousand images. This approach allowed us to obtain reliable measurements for pairs with very large difference of magnitude (up to 6). A significant part of the observed pairs had not been observed in the previous decades and show significant movement compared to their last measurement. We also report the discovery of a yet unobserved component for the star A 2455 (WDS 06426+1937).
