A mosaic of six, deep, CCD images in the light of the [O iii]5007 Å nebular emission line has been obtained with the 1.3-m Skinakas (Crete) telescope of the filamentary nebulosity surrounding P Cygni. The [O iii]5007 Å line discriminates against confusing galactic Hii regions along the same sight-lines and the new mosaic did not include the 4.8 mag. central star; a source of artifacts in the previous lower angular resolution observations. New giant “lobes” and “shells” are found to be clustered around P Cygni which must be the relics of historic eruptions between 2400 and up to ≈105 yr ago.
