Gamma And – γ And – Star system in Andromeda
While it seems simple, this star system has a complex hierarchy. Unfortunately only the main component can be resolved separately.

While the location has nice Bortle 4.5 sky, I’ve created this sketch surrounded by street lights. These lights made dark adaptation extremely difficult.
