We will present reconstructed images of Neptune's largest satellite Triton as part of an investigation of hemispheric asymmetry. The images we observed from the Hubble Space Telescope in July of 1997, using the Wide Field/Planetary Camera. The images were taken in several filters: F439W, F555W, and F791W. Image restoration was performed using the MISTRAL program (Mugnier, Fusco, and Conan 2003). We present the ratio between the filters to determine if there is any hemispheric color asymmetry at this time. The photometry of Triton appears normal in this data although Hicks and Buratti (2004) observe Triton to be anomalously red in August of 1997.
