Example of the visual inspection technique applied to a small 6″ region of M83. The small magenta circle (0.6″ diameter) shows a confirmed PN candidate, which appears as a point-like source of [O III] emission in the HST data. The yellow square shows an object that looks very similar in the MUSE data but is clearly extended in the HST data, thus disqualifying it from further consideration. Likewise, the cyan square shows an object with [O III] emission, which however aligns with a stellar source in V band. This demonstrates the power of using MUSE and WFC3 together to identify candidate PN at the distance of M83.
