Bubble in HOO
The Bubble Nebula (NGC 7635) is emission nebula in Cassiopeia constellation. Its formed by a powerful solar wind of a Wolf-Rayet star. It is a young star that emits strong ultraviolet rays that energise the surrounding molecular gas clouds to form a shape like a bubble. The diameter of the bubble is around 3-5 light years @ distance of about 7100 light years. Gear setup: Celestron Edge HD 8 f/7, Celestron F/R, Ioptron GEM 45, Celestron OAG w/ZWO 174MM, ZWO EFW 5 x 1.25 Baader SHO narrowband filters, ZWO ASI1600 MM pro cooled @ 0. Lights Ha 36 x 300, O iii 36x 300, Flats 20 each filter, Darks 20, Bias 50. Total integration 6 hrs. Captured by APT, Sharpcap pro, PHD 2. Stacked in APP, processed in PI as HOO with little crop & Topaz Denoise AI. For more details visit my astrobin webpage: astrob.in/27mdu4/0/
