   In this field of ~25-30 thousand stars are about 50 calibration stars known as Landolt stars (after Arlo Landolt who calibrated them). These calibration stars allow different telescopes to measure magnitude consistently. Finding them is the glamour part of science they don't tell you about. #astrophoto
