NGC 604

Telescope: Hubble Space Telescope, 2.4m Reflector, 57.6m FL
Camera: Wide Field Camera 2 (Detection range 120 nm to 1000 nm), about 2.7' field of view, 4 x 800 x 800 pixels
Exposure: An image layer captured through an H-Alpha filter is most commonly mapped to red as in the main image.
Image Center (J2000): RA 01h 34m, DEC +30° 47'

H-II region emission nebula within the M33 galaxy. The cluster of blue stars at its center cause it to glow. One of the largest H-II regions in the Local Group of galaxies. Apparent size 2' x 1'. The inset top left is the Hubble Team’s published image with the H-Alpha layer mapped to green/yellow.
