We present observations of C/2006 P1 (McNaught) obtained by the twin NASA STEREO spacecraft's SECCHI heliospheric imagers, and the ESA/NASA SOHO spacecraft's LASCO coronagraph during this most spectacular comet's apparition in January, 2007. One of the most striking aspects of McNaught's extensive dust tail was its clear system of striae, which displayed a mixture of ordered and quasi-random structuring of the comet's dust population. In combination with earlier LASCO observations of striae in C/2002 V1 (NEAT), our simulations of these quasi-linear dust structures in both comets provide unique new insights into the processes controlling these perplexing structures' formation and development. In addition, we report on our analysis of McNaught's ion and neutral gas tails using the two datasets.
