This paper presents the results of a 2014 program of photographic measurements of two multiple star systems (one a double, one a triple) not studied since their initial measurement in 1900.
This paper reports quantification and explanation of some sources of error in using the Reduc software to measure the PA and separation of double star images.
Measurements have been made of eight neglected southern multiple stars from the Washington Double Star Catalogue. Images were acquired using a Meade DSI CCD camera coupled to a 150mm f/8 refractor, and analysed using Losse’s Reduc software.
Measurements of six neglected southern multiple stars have been made using a Meade DSI CCD camera coupled to a 150mm f8 refractor.
