Crescent nebula NGC 6888
This image is a re-processing of my old & new data captured last year and this year. This beautiful nebula is called crescent nebula. Its mainly composed of Hydrogen & Oxygen gas. The powerful stellar wind that produced from Wolf-Rayet star is responsible for expanding & energizing Hydrogen gas to glow in red, and Oxygen to glow in blue. Actually, this star is in its final stage of life, which expel its outer layer of gases which appears as crescent in this nebula. This star is located in the central region. Lights Ha 48 x 300, O iii 40 x 300, total exposure of 7 hours. Gear setup: Ioptron GEM45, Celestron Edge HD8 @f/7, ZWO EFW 2”, Antila Ha 3nm, Antila O III 3nm, ZWO 2600MM @ 0. Captured by APT, Sharpcap pro, PHD2. Stacked in APP & processed in PS and Pixinsight.
