Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image is a composite of separate exposures acquired by the ACS/SBC, ACS/WFC, WFC3/UVIS 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 13 different filters used by the four instruments grouped as follows: Blue: ACS/SBC F150LP, WFC3/UVIS F225W (U) + F275W (U) + F336W (U), ACS/WFC F435W (B) + F606W (V) + Green: ACS/WFCF775W (I) + F814W (I) + F850LP (z), WFC3/IR F105W (Y) Red: WFC3/IR F125W (J) + F140W (JH) + F160W (H)

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
