| Instrument | HST>ACS/WFC and HST>WFC3/IR |
| Exposure Dates | July 2002 to March 2012, Exposure Time: 22.5 days (2 million seconds) |
| Filters | ACS/WFC: F435W (B), F606W (V), F775W (I), F814W (I), and F850LP (z) WFC3/IR: F105W (Y), F125W (J), and F160W (H) |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the ACS and WFC3/IR instruments. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image from the eight different filters used by the two instruments grouped as follows: Blue: ACS/WFC F435W (B) + F606W (V) Green: ACS/WFC F775W (I) + F814W (I) + F850LP (z) Red: WFC3/IR F105W (Y) + F125W (J) + F160W (H) |

| 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. |
