| Instrument | HST>ACS/WFC and HST>WFPC2 |
| Exposure Dates | September 1999, November 2006, and January 2007 |
| Filters | ACS: F658N (H-alpha + [N II]) and F606W (wide V) WFPC2: F502N ([O III]), F487 (H-beta) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the ACS and WFPC2 instruments on the Hubble Space Telescope. Three filters were used to sample narrow-wavelength ranges. One filter was used to sample broad wavelengths. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Red: F658N (H-alpha + [N II]) Green/cyan: F606W (wide V) Cyan: F502N ([O III]) Blue: F487 (H-beta) |

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
