Supernova remnants, planetary nebulae and the distance toNGC4214

We present narrow band, continuum subtracted H alpha , [S ii], H beta , [O iii] and [O ii] data taken with the Wide Field Camera 3 on the Hubble Space Telescope in the nearby dwarf starburst galaxy NGC4214. From these images, we identify seventeen new planetary nebula candidates, and seven supernova remnant candidates. We use the observed emission line luminosity function of the planetary nebulae to establish a new velocity-independent distance to NGC4214. We conclude that the PNLF technique gives a reddening independent distance to NGC4214 of 3.19 plus or minus 0.36Mpc, and that our current best-estimate of the distance to this galaxy ids 2.98 plus or minus 0.13Mpc.
