M421071 viewsMessier 42 (M42, NGC 1976) The Orion Nebula is the brightest star forming, and the brightest diffuse nebula in the sky. Shining with the brightness of a star of 4th magnitude, it is visible to the naked eye under moderately good conditions. The Orion Nebula is located at a distance of about 1,600 (or perhaps 1,500) light-years.
M46793 viewsMessier 46 (M46, NGC 2437) This open cluster is very rich, with 150 stars of mag 10-13 and probably a total population of over 500. The brightest of these stars are of spectral type A0, and each about 100 times more luminous than the Sun (the brightest is of apparent magnitude 8.7). This indicates an age of about 300 million years. As a special and famous feature which is also obvious in my photograph, a planetary nebula (NGC 2438, also FC 87) appears within the apparent borders of M46. This object appears to lie near the northern fringes of the cluster. However, this nebula is not a true member but is superimposed, or perhaps a passing "guest". The distance of the cluster is 4,600 light years and only about 2,900 light years for the nebula
M1940 viewsMessier 1, (M1, NGC 1952), The Crab Nebula is the most famous and conspicuous known supernova remnant, the expanding cloud of gas created in the explosion of a star as supernova which was observed in the year 1054 AD. It shines as a nebula of magnitude 8.4 near the southern "horn" of Taurus, the Bull. The distance is 6,300 light years.
M27910 viewsMessier 27, (M27, NGC 6853) The Dumbbell Nebula is perhaps the finest planetary nebula in the sky, and was the first planetary nebula ever discovered. Existing estimates for the distance reach from 490 to 3500 light years.
M20953 views Messier 20 (M20, NGC 6514) The Trifid Nebula in Sagittarius is a remarkable and beautiful object as it consists of both a conspicuous emission nebula and a remarkable reflection nebula component. The distance is 5200 light year.
M16832 viewsMessier 16 (M16) The Eagle Nebula is a conspicuous region of active star formation, situated in Serpens Cauda. The starforming nebula, a giant cloud of interstellar gas and dust, has already created a considerable cluster of young stars. The cluster is also referred to as NGC 6611, the nebula as IC 4703. The distance is 7000 light years.
My 7" refractor838 viewsThis is my 7" f/9 refractor mounted on an AP-1200 GTO.
Bubble Nebula997 viewsNGC 7635, also called the Bubble Nebula, is an emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. The distance is 11,000 light years.
M571142 viewsMessier 57 the Ring Nebula appears in the northern constellation of Lyra is a prominent example of a planetary nebula. This is a shell of ionized gas expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf. The distance is 2300 light years.
Moon915 viewsThe moon southern polar region.
M331011 viewsMessier 33 (M33, NGC 598) The Triangulum Galaxy is a prominent member of the local group of galaxies. This galaxy is small compared to its big apparent neighbor, the Andromeda galaxy M31, and to our Milky Way galaxy, but is more of average size for spiral galaxies in the universe. The distance is approximately 3 million light years.
62_Erato 1022 views62 Erato is a large and dark, probably carbonaceous main-belt asteroid. It is a member of the Themis asteroid family.Erato is the first asteroid to have been credited with co-discoverers, Oskar Lesser and Wilhelm Forster, who discovered it on September 14, 1860 from the Berlin Observatory. It was their first and only asteroid discovery.
