Abstract The Hubble Heritage Team will observe the entire Sombrero Galaxy (M104, NGC 4594) with a 6-point ACS mosaic. A color composite image will be released to the public via the Heritage website and an STScI photo release. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will observe the Sombrero Galaxay (M104, NGC 4594) with ACS/WFC in filters 435W, 555W and 675W. The exposure times are based upon flux calibrated data from WFPC2 program 5512. The exposure times for the SDSS-r filtered images (F625W) will saturate the nucleus somewhat, but this is acceptable.
