Pickering’s Triangle was discovered in 1904 by Williamina Fleming of the Harvard Observatory while examining photographic plates of the area. The object was named in honor of her boss, astronomer Edward Charles Pickering, then director of the Observatory. Pickering’s Triangle goes by a number of aliases, including Pickering’s Wedge, Fleming’s Triangular Wisp, and Simeis 3-188. Current estimates place this supernova remnant at about 1800 light years from Earth. The entire Veil Nebula complex, of which Pickering’s Triangle is but a portion has an apparent diameter of about 3° or nine full moons! The tangled mass of star ejecta in the main body of the Triangle along with the fine, twisted filaments trailing out from that region make this object a beautiful and rewarding target for amateur astro-imagers.
