| Instrument | HST>WFC3/UVIS |
| Exposure Dates | July 6-17, 2010, Exposure Time: 4.8 hours |
| Filters | F225W (U), F336W (U), F438W (B), F487N (H-beta), F502N ([O III]), F547M (y), F657N (H-alpha + [N II]), F673N ([S II]), and F814W (I) |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the WFC3 instrument on HST. Several filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: White: F225W (U) + F336W (U) + F438W (B) Blue: F487N (H-beta) Cyan: F502N ([O III]) Aqua: F547M (y) Red/orange: F657N (H-alpha + [N II]) Yellow/green: F673N ([S II]) Red: F814W (I) |

| 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. |
