Messier 42: Amateur Image vs. Hubble Image
Two images of Messier 42 (M42), better known as the Orion Nebula. The left image was taken with an 8-inch Schmidt-Cassegrain telescope using a 0.63x focal reducer and a DSLR Camera. The right image was taken by NASA’s Hubble Space Telescope. The Hubble image uses 520 different Hubble exposures taken in multiple wavelengths of light; this mosaic contains over one billion pixels. Hubble imaged most of the nebula, but ground-based images were used to fill in the gaps in its observations. The orange color in the image can be attributed to hydrogen, green represents oxygen, and the red represents both sulfur and observations made in infrared light.
