An early analysis of Chandra observations of the planetary nebula NGC 6543 suggested that the location and the derived temperature for the X‐ray–emitting region are inconsistent with the abundances measured for this object. We revisit Chandra observations of this source (following significant updates to both the reprocessing and extraction software) in order to propose a resolution to this apparent anomaly. Our reanalysis using abundances found from observations in the infrared, optical, and ultraviolet suggests that the location and temperature of the X‐ray emission from NGC 6543 is consistent with nebular abundances expected for the source.
