We identified 21 new Planetary Nebula ( PN ) candidates in the Sculptor Group galaxy NGC 55 .
We determined a most likely distance of 2.00 \pm 0.2 Mpc using the Planetary Nebulae Luminosity Function ( PNLF ) method .
The distance to NGC 55 is larger than previously determined distances , which means that the Sculptor Group is a bit further away from the Local Group than previously thought .
The distance to NGC 55 is again similar to the distance of NGC 300 , adding support to the suggestion that these galaxies form a bound pair .
