  Vdb 75,DG 99,IC 444 (Gemini).jpg - vdB 75,DG99,IC444,BSF 51 (Gemini) * January 2014 * ASA N12 astrograph (f/3.6, 1078mm) * DDM85 mount * FLI ML8300 at -25ºC * LRGB Optec filter set * L: 510m R: 140m G:130m B:140m *vdB 75 is a reflection nebula visible in the constellation of Gemini .The cloud is located in the western part of the constellation, in a very rich field of background stars, surrounding the bright giant star 12 Geminorum , of apparent magnitude equal to 6.95. The identification of its location is not difficult, thanks to the presence of the brilliant μ Geminorum , a red giant star of magnitude 2.87 and therefore clearly visible even in the nights are not perfectly clear, the nebula is located about a degree to the northwest, on the edge of an open cluster known as widely dispersed Cr 89 .vdB 75 is the brightest part of the nebula IC 444, which is in turn associated with an emission nebula indicated with the abbreviation Sh2-249 ; this nebula is part of the H II region BFS51, located in the central regions of the Complex hazy molecular Gemini OB1 , a vast association of stars and diffuse nebulae placed at nearly 2000  parsecs away from the solar system , the inner edge of the Perseus Arm . At the H II region are also associated with the dark nebulae LDN  1564 and LDN 1567. [3]Notes [ edit | edit source ]WIKIPEDIA^ a b Simbad Query Result .
