Here, try this. From Orion's belt view through Taurus the Bull and the Pleiades, the little star cluster otherwise known as the "Seven Sisters" (and logo of Subaru).
Machholz will be a fuzzy little ball just up and to the right of the Pleiades this evening. Good luck spotting it! It's been so overcast here in southeastern Wisconsin, dense fog this evening, that I've only had occasion to view this comet once since it's been rising steadily overhead.
