| About the Data |
| Note: |
The release image of M51 was created from WFPC2 archived HST data
from science programs by N. Scoville (Prop 7375), H. Ford (Prop
5123), and R. Kirshner (Prop 5777). HST data have been superimposed
onto BVRI and Ha ground-based data, taken by Travis Rector (NOAO)
at the 0.9 meter telecope located on Kitt Peak, Tucson, AZ (NOAO/AURA/NSF).
