Planetary nebulae as standard candles. III - The distance to M81The results of a survey for PN in the nearby Sb galaxy M81 are reported, including the identification of 185 PN candidates. A distance to M81 of 3.50 + or - 0.40 Mpc is derived using the methods outlined by Ciardullo, et al. (1989). This value compares very well with values derived using traditional methods. Based on this agreement, it is concluded that PN are as good as, or better than, other standard candles for deriving distances to galaxies beyond 10 Mpc.
