A double star in the southern constellation of Telescopium, comprising a white main sequence star designated HD 183845 A, shining faintly at eleventh magnitude, and an even fainter twelfth magnitude star close by to the north, designated HD 183845 B. This pair is listed in the Index Catalogue as a multiple star with the catalogue number IC 4868, although in fact the stars seem to represent an optical double. The two stars appear to be close together as seen from Earth, but based on their parallax values, they lie some 1,300 light years away, and are actually separated from one another by a distance of more than a hundred light years.

HD 183845 A is the comparatively brighter star marked by the reticle in the centre of this image, and HD 183845 B is the fainter star immediately to the north. Imagery provided by Aladin sky atlas
