Paired quotient (r′ – Hα) and colour (u′, g′ , r′) images from VPHAS+ of selected PNe centred on their coordinates from HASH. North is up and east is to the left. The coloured markers overlayed on the quotient images show Gaia detections with colour corresponding to BP – RP as shown in the legend and shapes indicating matches from this and previous works. The broadband colour images (with colours derived following Lupton et al. 2004) are useful for comparison as they better capture the range of stellar colours and highlight blue central stars.
