This paper details the results of photographic measurement of the triple star system RST5413A-B / HJ4857A-C in Norma over two years – 2014 and 2015.
This paper presents the results of a 2013/early 2014 programme of photographic measurements of seventeen southern multiple stars. The images were obtained using a Meade DSI CCD camera in conjunction with an equatorially mounted 150-mm f/8 refractor and software programme AstroPlanner 2.1 (Rodman).
Through the second half of 2014 measurements were completed of the following southern multiple stars as listed in the Washington Double Star Catalogue. Using a 400mm f4.5 Newtonian reflector fitted with a Meade DSI 2 camera and software program Astroplanner V2.1 (Rodman) the obtained images were analysed using Losse’s Reduc software.
