This cornerstone project, which will be held April 2 ? 5, 2009, will bring together observers from all over the world to use and look through telescopes to admire the heavens. We will have a public voting session that will highlight six astronomical objects that have never been viewed with Hubble. Objects have been preselected to fit in the field of view of the WFPC2 camera, and that are observable during the April viewing window. The voting session will close on March 1st, 2009, and the most popular candidate will be observed and released during the ?100 Hours of Astronomy? event. Observations will be made with four filters for a composite press release image. We ask for eight orbits of Hubble time from the Director?s Discretionary pool of orbits. This will allow a modest amount of S/N for the candidate that will be selected. The archive science data products will become public at the time of release. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will obtain deep and well-sampled exposures of the target voted on by the public. We employ a dither box pattern, with two long exposures per orbit with broadband B, V, I, and redshifted H-alpha (F673N) filters. The data will be drizzled to a smaller output pixel scale to enhance resolution. Our carefully prepared dataset will be ingested into MAST as a High Level Science Product (HLSP), so that it will be accessible via archive searches.
