Subaru + FOCAS observations of PNs in NGC 821
Abstract
We present preliminary photometry of 122 PNs discovered in the elliptical galaxy NGC 821. We build the PN luminosity function (PNLF), which gives a distance modulus m - M = 31.9$±$0.3, in good agreement, within the uncertainties, with the SBF distance modulus 31.91$±$0.17 obtained by Tonry et al. (2001).
