This is my second attempt this season at capturing and processing the Omega Nebula. This time I managed to capture 8 hours of narrowband data across four nights - lucky we finally had a good run of clear skies. I processed the data by putting Ha in Red and OIII in Green and Blue. In this video I also discuss how to combine the different filters and cut through the brightness of the nebula with PixInsight Here is more info on the hardware and software: • Target: • Omega Nebula (M17) • Imaging Telescope: • Explore Scientific 127mm ED Refractor (952 focal length) • Focuser: • MoonLite 2.5 Focuser with Motor Auto-Focus • Field Flattener: • HoTech 2 SCA Field Flattener • Mount: • Celestron CGX • Polar Alignment: • QHYCCD PoleMaster • Imaging Camera: • ZWO ASI1600MM-Cool • Frames: • Frames: • Astronomik Ha: 60x240 • Astronomik OIII: 60x240 • Integration: 8 hours • • Ha: Gain=139, Offset=21 • OIII: Gain=75, Offset=15 • Guide scope: • Orion ST80 • Guide Camera: • Lodestar X2 • Guide Software: • PHD2 • Calibration Frames: • Darks: 50, Bias: 50, Flats: 50 • Capture software: • Sequence Generator Pro (SGP) • Stacking software: • PixInsight • Post Processing: • PixInsight, PhotoShop • Dew Shield, Dew Heater Strip • Astrobin: https://astrob.in/355891/B/
