Category: Multiple star.
Class:
Constellation: Cap
Data: mag 3.8 size
Position: RA 20:18 DEC -12:31
Description:
Alpha Cap, a separable double star with naked eye. Obviously, I separate well Alpha1 and Alpha2, each one raising a colour white-yellow. What I tried to find is the companion of Alpha1 but, unfortunately, it remains invisible, probably because of the large differential of brightness between 2 stars.
