NGC 2174, Monkey Head Nebula, Sharpless Sh2-252
The Hubble data are from proposal 13623: Hubble Heritage Team/STScI/AURA: Z. Levay (PI; STScI), K. Noll (GSFC), and M. Mutchler, J. Mack, C. Christian, M. Livio, L. Frattare, J. Sokol, and S. Meyett (STScI). High-level science products for these data are available from the MAST archive.
F105W (Y), F125W (J), and F160W (H)
This composite image includes exposures acquired by the WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample broad 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:
Blue: F105W (Y)
Green: F125W (J)
Red: F160W (H)
