I was intrigued by Dylan O’Donnell’s video about using narrowband and broadband data to produce a more natural looking hybrid image of emission nebula objects. Specifically the use of H-alpha, Green and Oxygen III. As coined by Dylan – HaGO!
So I set out to collect some data using my Esprit 100 triplet refractor and the QHY268M cooled cmos camer. My test object was the Elephant Trunk nebula IC1396. I collected nearly 7 hours of data using Optolong Ha, green and OIII filters. I then used PixInsight to combine these light channels and produce the final image.
Below is a video I made about the HaGO palette with more details.
What do you think of my HaGO image? Commment below!
