The AAQ maintains a database of members’ observations of selected variable stars in the southern skies. This section of the web site provides charts for several of these stars. For each star there is a series of charts, commencing with a wide field view of the relevant region of the sky for identification of the area of interest with the unaided eye, followed by narrower fields of view for observations with binoculars and with telescopes.
The charts for the naked eye, binoculars and Newtonian reflecting telescopes (including Dobsonians) have a standard orientation (i.e.), north is up, and west is to the right. Charts that would be used with most refracting telescopes and with Schmidt-Cassegrain telescopes are reversed (i.e.), north is up, and west is to the left.
All charts except those for use with the naked eye identify comparison stars – stars of known magnitude (brightness) with which the variable stars are compared. The numerical values of the magnitude are shown on the charts with the decimal point removed, to avoid confusion with faint stars. Thus, a magnitude of 3.8 will be shown as 38, a magnitude of 10.0 will be shown as 100 and a magnitude of 10.3 will be shown as 103.
Please contact the Variable Stars Director if you find any errors on the charts.
