Despite years of effort, the impact of central star binarity on planetarynebula formation and shaping remains unclear. This is hampered by the fact thatdetecting central star binarity is inherently difficult, and requires veryprecise observations. The fraction of planetary nebulae with binary centralstars therefore remains elusive. This work presents initial results of centralstar analysis using data from the VST H$\alpha$ Survey of the Southern GalacticPlane and Bulge (VPHAS+). The true central star of PN Hf 38 has been revealed,and it exhibits a 0.465$\pm$0.334 $i$ band magnitude excess, indicative of aM0V companion.
