We present narrowband imaging results of Deep Impact target Comet 9P/Tempel 1. An on-going observational campaign from Lowell Observatory was begun in March to characterize the gas and dust morphology as a function of viewing geometry and season, and to investigate the newly released dust and gas as a function of time following the impact of the DI projectile. Prior to the encounter, dust imaging shows a persistent jet/fan, and evidence for rotational variations by early June. Fully calibrated, continuum-subtracted gas imaging reveals CN morphology which is not co-spatial with the dust jet/fans, but which also varies from night-to-night, presumably due to nucleus rotation. Representative images from throughout the apparition will be shown, along with results taken during an 11-day run centered on the time of the encounter.
