Arkab Posterior

Its story
Arkab Posterior is the «rear» of the Arkab pair in Sagittarius; the name, in Arabic, refers to the tendon joining the archer's leg to his bow. It is a yellow-white star 134 light-years away, part of a double asterism the naked eye barely separates. Its light crossed space during the entire period in which photography travelled from the daguerreotype to the digital sensor.
