DSS image of M 105. Overplotted are the PN candidates from the Subaru survey (blue crosses), PNe from the ePN.S survey (Pulsoni et al. 2018, green pluses), and the e²PN.S survey (this work, red pluses and crosses). PNe in NGC 3384 from Cortesi et al. (2013a) are denoted with green circles. The red and green rectangles denote the ePN.S and e²PN.S fields, and the dashed blue rectangle indicates the SuprimeCam footprint. The grey hatched regions indicate the two HST fields analysed in Lee & Jang (2016). The scale bar in the lower right corner denotes 10 kpc. North is up, and east is to the left.
