 		 This is another delightful pair. (This Dunlop had great taste!) It is easily found forming the apex of a flattened triangle with both Alpha and Beta Cent. 
Again a long period is suggested with little change. 
 
Comments: A wide Whitish and Blue pair with other stars in the field. 
Fine object for small telescopes. HS 2.

 		 Easy split at lowest power. Primary displayed gold to a burnt orange colour secondary seemed pale blue. 
 
Notes Located between A and B Cent this star seems in keeping with most Dunlop stars – ie attractive colour combinations. Of note is a faint 11th mag field star in PA 00.

 		 Beautiful double. Wide separation and colorful. Actualy, DUN 159 is an another multiple star (four components) where its three components are visible at high magnification (at least at 267x). AB are easily split at low power (71x), and different colours and magnifications are evident. A is yellowish and much brighter and B is bluish and fainter. The third component (C) is very faint and is lain far away, at North of AB.
