| About The Data | |
| Data Description | The Hubble images were created from data from the calibration proposal : M. Sirianni (STScI/ESA), M. Chiaberge (STScI/ESA/INAF), A. Suchkov (Johns Hopkins University), and N. Grogin (STScI). Acknowledgments for NGC 6217 Observers: M. Sirianni (STScI/ESA), M. Chiaberge (STScI/ESA/INAF), A. Suchkov (Johns Hopkins University), and N. Grogin (STScI) Data Analysis: M.

| Instrument | HST>ACS/WFC |
| Exposure Dates | June-July 2009, Exposure Time: 3.0 hours |
| Filters | F435W (g), F625W (r), F658N (H-alpha + [N II]), and F814W (I) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Four filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Red: F814W (I) + F658N (H-alpha + [N II]) Green: F625W (r) Blue: F435W (g) |
