Die Helder ster is Algieba in Leo met `n magnitude van 2. Links binne die wit sirkel (42mm oogstuksirkel) is die ster HD 89930  (magnitide 7).Regs bo in wit sirekl is die veranderlike ster Leo 40 (Mag 4.8). Op 15 Februarie is Vesta ook naby `n ster. Met behulp van die sterre kan jy nou maklik vir Vesta opspoor.
