The Pleiades (M45), also known as "The Seven Sisters". Yeah, sister #7 does not look much brighter than sister #8 , at least to me! The extended striations seen around the four brightest siblings are dust clouds reflecting the light from these hot (B-type) stars. The pinkish-red nebulosity seen to the left of the bright star "Merope" (23 Taurus) is an emission component from ionized hydrogen gas. If you want to see it for yourself, better hurry, because this open cluster of young stars is expected to disperse in only about 250 million years.
