Constellation: Cap
Data: mag 3.3  size 
Position: RA 20:21  DEC -14:46
Description:
In Capricornus, located in the NW portion of the constellation. Bright double star, the components are distinguished individually with a remarkable facility. The primary is of color green and blue for the secondary. At my great surprise, I notice a third member in the system whereas, in my notes, Dabih is regarded as only double. According to my estimate, it is magv = 8 and forms an isosceles triangle with the two others. At the time of this observation, it pointed in direction E compared to the primary star. Dabih thus forms a very beautiful trio with a good contrast of color.
