Horse-head nebula in Ha RGB
Horsehead nebula IC 434, is a beautiful emission nebula composed mainly of ionised Hydrogen gas that emits red light. The dark shape that resemble a horse head is a dark nebula that hides the stars behind it (B33). On the left, is another Hydrogen glowing gas cloud called Flame nebula NGC 2024. Alnitak star is shining just above the Flame nebula. Alnitak is one of stars that forming Orion belt (The Hunter). Also, this region of the sky contains a Reflection nebula just below the Horsehead nebula. NGC 2023 is a blue reflection nebula, it is composed of clouds of gases that reflect the young stars light to glow in blue light. All those nebulae are about 1500 light years from Earth. Gear setup: ES 102 APO f/7 @ 713mm, F/F zero, iOptron GEM 45, guided by ZWO mini guide scope and ZWO 120MM-S, ZWO 2600MC cooled @ 0, Optolong L-pro & Ha filter. Light subs 70 x 120sec L- Pro filter and 15 x 180sec in H-alfa filter, 20 Darks, 50 Bias, 20 Flats. Total integration of 3 hours. Captured by APT, Sharpcap pro and PHD2. Stacked in APP and processed by PI. For more image details visit my astrobin page: www.astrobin.com/full/g780si/0/
