Brain on fire
This Brain-like nebula or Crescent nebula NGC 6888, is emission nebula about 5000 light years from Earth. Its located in Cygnus constellation. The nebula is an expanding shell of gases results from Wolf-Rayet star in the centre of the nebula. This hot powerful star produces a fast speed solar winds that collide with the older outer shell gases. The impact is energize and ionize the outer shell gases to glow up in Hydrogen and Oxygen emission lines (Red & Blue in colour respectively). Captured over 2 nights in HOO palette with total integration of 4hrs & 20min. Gear setup: ES 100 APO CF, iOptron GEM45 guided by ZWO mini guidescope and ZWO ASI120MM-S, EFW 5x1.25, Baader Ha 6.5nm & O iii 6.5nm filters, ZWO ASI1600MM pro cooled @ 0. Acquisition by APT, Stacked by DSS and processed by PS. For more image details, check my astrobin link: www.astrobin.com/8d6qec/
