BP Piscium is a high Galactic latitude star with a compact dusty, gaseous disk, polar jets, and Herbig-Haro objects. In an effort to study the large scale dust features surrounding this star, we have obtained HST NICMOS and WFPC2 images of BP Piscium. Our NICMOS images consist of polarimetry with NIC1 and coronographic polarimetry with NIC2. Both sets show an extended region with centro-symmetric polarization which extends beyond the 0.2” disk seen in near-IR AO images (Zuckerman et al. 2008, ApJ, 683, 1085). This connects the 0.1” scale seen in AO with the CO radio line emission seen at 1” scales. Our WFPC2 images consist of visible, H alpha, and polarimetry of BP Piscium as well as H alpha images of the North-Eastern jet. These data serve to further our ongoing efforts to understand the disk and dust properties of BP Piscium. We acknowledge the use of observations made with the NASA/ESA Hubble Space Telescope associated with proposal 11152.
