![]() Little Dumbbell Nebula (M76): This nebula looks like a dumbbell.NGC 1260: This is either a tight spiral galaxy or a lenticular galaxy.NGC 1023: This is a barred spiral galaxy.Abell 426: Abell 426 or the Perseus cluster is a massive group of thousands of galaxies.M34: M34 is an open cluster that may be seen (barely) with the naked eye and is easily resolved with a small telescope.The double star cluster is easily observed with the use of a small telescope. NGC 869 and NGC 884: Together, these two objects form the Double Cluster.The constellation contains interesting deep-sky objects, including several nebulae and the Perseus cluster of galaxies. While the galaxy is not very obvious in this region, Perseus does lie in the galactic plane of the Milky Way. The California Nebula, NGC 1499, has a shape similar to that of the state of California. Seven of the stars in the constellation are known to have planets. GK Persei: GK Persei is a nova that reached peak brightness in 1901 with a magnitude of 0.2.One of its two members is a neutron star. Zeta Persei: The third-brightest star in Perseus is a blue-white supergiant with a magnitude of 2.86.The color of its primary star is blue-white. Sometimes Algol is known as the Demon Star. It is an eclipsing binary that ranges in magnitude from 2.3 to 3.5 over a period of 2.9 days. Algol is not, however, a true variable star. Its variable brightness is readily seen with the naked eye. Algol: Also known as Beta Persei, Algol is the best-known star in the constellation.Mirfak is a member of the Alpha Persei Cluster. Other names for this star are Mirphak and Alpha Persei. Mirfak: The brightest star in Perseus is a yellow-white supergiant.Notable stars in the constellation include: There are 19 stars in the constellation's main asterism, but in light-polluted areas only two of them (Mirfak and Algol) are bright. Mirfak is the brightest star in Perseus and the easiest to spot. Perseus is prominent in the northern sky of the Northern Hemisphere in the spring and is also visible in the northern part of the Southern Hemisphere. Camelopardalis and Cassiopeia are to the north of Perseus, while Andromeda and Triangulum are to the west. The constellations Aries and Auriga (with bright yellow star Capella) lie to the east of Perseus. The other notable star is Algol, a blue-white star that forms a line with Mirfak to identify the middle of the constellation. The brightest is Mirfak, a yellow star at the mid-point of the constellation. Once you have spotted Perseus, look for its two brightest stars. If Cassiopeia resembles an "M," Perseus will be the group of stars below the right part of the zig-zag. If Cassiopeia resembles a "W," Perseus will be the group of stars below the left part of the zig-zag. To locate Perseus, look to the north, where Cassiopeia forms a bright "W" or "M" (depending on its orientation). Fortunately, it is located near Cassiopeia the Queen, one of the most visible formations in the sky. Perseus the Hero is not as bright or as easy to recognize as some of the other constellations. Locate Constellation Cassiopeia in order to find Perseus. ![]()
