WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun. WR 134 was one of three stars in Cygnus observed in 1867 to have unusual spectra consisting of intense emission lines rather than the more normal continuum and absorption lines. These were the first members of the class of stars that came to be called Wolf-Rayet stars (WR stars) after Charles Wolf and Georges Rayet who discovered their unusual appearance Photo: @dainjason Integration time: 27 hrs Hydrogen, Oxygen and RGB stars (narrowband gain 200, broadband gain 120) Telescope: Skywatcher Esprit 120 ED APO Imaging Camera: ZWO ASI 294MM Pro Guiding: Starfield 50mm guide scope with ZWO ASI290MM guide camera Filter: Optolong Ha, Oiii (7/6.5nm) and RGB filters Mount: Skywatcher EQ6R-Pro Calibration: Flats and flat darks Hardware Control: ASIAIR Pro, Pegasus Power Box, ZWO EAF and EFW Processing: The selected images were pre-processed and processed using Pixinsight. #space #nebula #astro #astrophotography #astrophoto #astrophotographer #spacephotography #cosmos #stars #nightsky #nightphotography #deepsky #deepskyphotography #telescope #narrowband #telescopephotography #spacephotography #spacephotos #nightskyphotography
