A far more challenging target toward the northwest, the Taurus Molecular Cloud 1 (TMC-1) can be found just north of the Hyades and extends westward past the California Nebula (NGC 1499) and the Pleiades (M45).

The H-beta will also work on a few other similarly dim objects, like the California Nebula, but it's certainly not a general-use filter.
Perseus is also the home to the large diffuse emission nebula NGC 1499, the California Nebula. This is particularly difficult for visual observation due to its large size and low surface brightness--a rich field telescope and an H-beta filter will probably be needed to see much of it visually, but if you have a good night, it may be worth trying to view it with binoculars.
Located in Perseus, the California Nebula is a challenge to observe visually in any telescope, and long exposures are required to photograph its entirety.
