Abstract Deep CCD images of PV Cephei reveal a faint, red "counterfan", opposite the star from the optically prominent fan previously known. This counterfan is clearly associated with the redshifted lobe of the PV Cephei molecular outflow, and its detection supports the contention that cometary nebulae are the optical counterparts of bipolar molecular outflows. The relative colors of the two halves of the optical nebulosity can be explained by differential reddening between the two lobes. Photometry of the gap between the stellar image and the bright optical fan is consistent with this gap being totally "black", indicating either high (≡4) values of AV due to a circumstellar disk or a total lack of material within the gap.
