Description:

NGC 2175, aka the Monkey Head Nebula, is found in the constellation Orion. NGC 2175 is part of Sharpless 2-252, which is an extended H-II region that is approximately 7200 light years away. Please note that there is some discrepancy in the literature as to the designation as NGC 2175 or NGC 2174...for a discussion see S. J. O'Meara in Deep-Sky Companions: Hidden Treasures: Cambridge 2007.
