    Messier 41.jpg

    Messier 41 (also known as M41 or NGC 2287) is an open cluster in the Canis Major constellation. It was discovered by Giovanni Batista Hodierna before 1654 and was perhaps known to Aristotle about 325 BC.M41 lies about four degrees almost exactly south of Sirius, and forms a triangle with it and Nu2 Canis Majoris—all three can be seen in the same field in binoculars. The cluster itself covers an area around the size of the full moon.It contains about 100 stars including several red giants, the brightest being a spectral type K3 giant of apparent magnitude 6.3 near the cluster's center, and a number of white dwarfs. The cluster is estimated to be moving away from us at 23.3 km/s.The diameter of the cluster is between 25 and 26 light years. It is estimated to be 190 million years old, and cluster properties and dynamics suggest a total life expectancy of 500 million years for this cluster, before it will have disintegrated.(Wikipedia) Constellation Canis Major Right Ascension 06h 46.0m Declination −20° 46′ Distance 2,300 ly (710 pc) Apparent magnitude (V)4.5 Apparent dimensions (V)38 arcmin DAY:Tuesday DATE:1/3/16 TIME:20:00 SCOPE:Dob Sky-Watcher 10PX F.L.1200/f4.7 EYEPIECE:T/S 30mm Plossl 2 inches F.O.V. 68° LOCATION:Mammari

    The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant in the constellation of Taurus. The now-current name is due to William Parsons, 3rd Earl of Rosse, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab.Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion (Wikipedia).

    Messier 103.jpg

    From the album: Gallery

    Messier 103 (also known as M103, or NGC 581) is an open cluster where a few thousand stars formed in the constellation Cassiopeia. This open cluster was discovered in 1781 by Charles Messier's friend and collaborator Pierre Méchain.It is one of the most distant open clusters known, with distances of 8,000 to 9,500 light-years from the earth and ranging about 15 light-years apart. There are about 40 member stars within M103,two of which have magnitudes 10.5, and a 10.8 red giant, which is the brightest within the cluster. Observation of M103 is generally dominated by the appearance of Struve 131,though the star is not a member of the 172-star cluster.]M103 is about 25 million years old.

    Messier 52 (also known as M52 or NGC 7654) is an open cluster in the Cassiopeia constellation. It was discovered by Charles Messier in 1774. Due to interstellar absorption of light, the distance to M52 is uncertain, with estimates ranging between 3,000 and 7,000 light years. One study identified 193 probable members of the cluster, with the brightest member being magnitude 11. Messier 52 is estimated to be about 35 million years old.

    The Beehive Cluster (also known as Praesepe (Latin for "manger"), M44, NGC 2632, or Cr 189), is an open cluster in the constellation Cancer. It is one of the nearest open clusters to Earth, containing a larger population of stars than other nearby bright open clusters. Under dark skies, the Beehive Cluster looks like a small nebulous object to the naked eye; as known since ancient times. Classical astronomer Ptolemy described it as "nebulous mass in the breast of Cancer", and it was among the first objects that Galileo studied with his telescope.

It was discovered by Charles Messier in 1764. This cluster can be seen in binoculars. In telescopes, lowest powers are best. The brightest stars of Messier 29 form a "stubby dipper", as Mallas says it. The four brightest stars form a quadrilateral, and another three, a triangle north of them. It is often known as the "cooling tower" due to its resemblance to the hyperboloid-shaped structures. A few fainter stars are around them, but the cluster appears quite isolated, especially in smaller telescopes. In photographs, a large number of very faint Milky Way background stars shows up. Messier 29 can be found quite easily as it is about 1.7 degrees south and little east of Gamma or 37 Cygni (Sadr). In the vicinity of Messier 29, there is some diffuse nebulosity which can be detected in photographs.(Wikipedia) SCOPE: Dob 10px Synta F.L.1200/f4.7 EYEPIECE: T/S 30mm plossl 2inces F.O.V. 68° DAY:Sunday DATE: 2/10/16 TIME: 23:36 local time LOCATION: Mammari

    The Brocchi's Cluster, Collinder 399 (Cr 399) is a random grouping of stars located in the constellation Vulpecula near the border with Sagitta. Collinder 399 is known as Al Sufi's Cluster or Brocchi's Cluster. The brighter members of this star cluster form an asterism also known as the Coathanger. It was first described by the Persian astronomer Al Sufi in his Book of Fixed Stars in 964. In the 17th century, it was independently rediscovered by the Italian astronomer G. B. Hodierna. In the 1920s, Dalmero Francis Brocchi, an amateur astronomer and chart maker for the American Association of Variable Star Observers (AAVSO), created a map of this object for use in calibrating photometers. In 1931, Swedish astronomer Per Collinder listed it in his catalogue of open clusters (Wikipedia).

    Kemble's Cascade

    From the album: Gallery

    Kemble's Cascade, (Kemble 1), located in the constellation Camelopardalis, is an asterism — a pattern created by unrelated stars. It is an apparent straight line of more than 20 colourful 5th to 10th magnitude stars over a distance of approximately five moon diameters, and the open cluster NGC 1502 can be found at one end. It was named by Walter Scott Houston in honour of Father Lucian Kemble (1922–1999) Father Lucian Kemble was also associated with two other asterisms, Kemble 2 (an asterism in the constellation of Draco that resembles a small version of Cassiopeia) and Kemble's Kite (an asterism that resembles a kite with a tail which is also in the constellation of Camelopardalis). In addition, an asteroid, 78431 Kemble, was named in his honour.(Wikipedia) SCOPE: 70mm Altair Astro 420/f6 EDD FMC Starwave EYEPIECES: Edmund Optics 32mm RKE DAY:Saturday DATE:21/1/17 TIME:22:00 LOCATION:Mammari

    The Andromeda galaxy, known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way. Its name stems from the area of the sky in which it appears, the constellation of Andromeda. Like the Milky Way, the Andromeda Galaxy has satellite galaxies, consisting of 14 known dwarf galaxies. The best known and most readily observed satellite galaxies are M32and M110. Based on current evidence, it appears that M32 underwent a close encounter with the Andromeda Galaxy in the past. M32 may once have been a larger galaxy that had its stellar disk removed by M31, and underwent a sharp increase of star formationin the core region, which lasted until the relatively recent past. M110 also appears to be interacting with the Andromeda Galaxy, and astronomers have found in the halo of the latter a stream of metal-rich stars that appear to have been stripped from these satellite galaxies.M110 does contain a dusty lane, which may indicate recent or ongoing star formation.(Wikipedia) Constellation Andromeda Right ascension 00h 42m 44.3s Declination +41° 16′ 9″ Characteristics Type SA(s)b Size ~220 kly (diameter) Apparent size (V) 3.167° × 1° DAY:Tuesday Wednesday DATE:21/11/17 22/11/17 TIME:23:00 SCOPE:Celestron Nextstar 130mm S.L.T. 650/f5 EYEPIECE:Explore Scientific 20mm F.O.V.68° LOCATION: Mammari
