  IC5076 (vdB 137),vdB 138,LDN 958,GN 20.57.4,LDN 955 (Cygnus).jpg - IC 5076 (vdB 137),vdB 138,LDN 958,LDN 955, GN 20.57.4 ,Star 59 Cyg (Cygnus)* August 2019 * Telescope CFF 135 (f/6.7, 930mm) * ASA DDM85 mount * G3 16200EC Moravian CCD * Baader LRGB filter set * L: 651minutes R: 441min G:364 min B:462min *C 5076 (also known as vdB 137) is a reflection nebula visible in the constellation of the Swan.It is located in the northern part of the constellation, about 2° north of the central part of the North American Nebula; the most suitable period for its observation in the evening sky is between June and November for observers located in the northern hemisphere regions.The nebula is linked to the star HD 199478, a blue supergiant of spectral class B8Iae with strong peculiar emission lines, to the point of being classified as a Be star; its apparent magnitude is 5.73 and being a pulsating variable (V2140 Cygni) shows variations in brightness in the order of 0.1 magnitudes. Distance seems to be close to 1750 parsec (5700 light years), being in the same galactic region of the great nebulous complex of Cygnus X along with the nearby open cluster NGC 6991. VdB 138 is a small reflection nebula, visible at the upper center of this image. The dark nebulae LDN 958 (top right), with a small grayish nebula (GN 20.57.4) and the dark nebula LDN 955 (top central image) can also be seen. The bright blue star on the right side is 59 Cygni, magnitude 4.53.The reflection nebula IC 5076 was first found on a photographic plate by Isaac Roberts - an English pioneer in astrophotography. With its modern and powerful 20-inch reflector (at that time) (silver-plated glass mirror) it found the nebula on September 13, 1895. The open cluster with the NGC 6991 designation is also catalogued at IC 5076. Archinal/Hynes refers to two observations by William and John Herschel, the cluster refers to a large 25' group of 35 brightest stars. Credits: Wikipedia-Antonio F.Sanchez.
