Abstract
We present HST-WFPC2/H alpha deep images of the ejected nebula M1-67. Our d ata suggest that M1-67 is the imprint of a previous, slow LBV wind ejected from the central star WR124, now a WN8 star. We find evidence that the LBV wind is highly variable and anisotropic. Some dense, persisting clumps have possibly been ejected directly from the stellar surface.
