Description:
A nice binary star, not that close to eachother, but with large difference in brightness. The colour is best noticeable with fresh, non dark adapted eyes. The primary member has a golden colour with a touch of green while the companion is deep blue with a very little purplish tint. The strong moonlight combined with moderate humidity is not a favorable condition for observation, perhaps that's why the field is lacking faint stars.
