This is one of the first light images with our new setup at the TURMX Observatory, hosted at the e-EyE Astronomical Complex in Extremadura, Spain. It is only a quick snapshot with a total of 6 hours of exposure time with the Baader CMOS-optimized ultra-narrowband filters as a first test of the system. Turned out very nicely – the filters perform very well.<\/p>\n\n\n\n

The target is the famous Crescent Nebula, NGC6888, in the constellation Cygnus. The nebulosity is formed by the outer shells of the Wolf-Rayet star\u00a0WR 136, which has undergone episodes of significant mass loss. In combination with strong stellar winds this material forms the intricate nebula, which is still expanding. <\/p>\n\n\n\n
