IC1396 captured over about 11 months due to bad weather and time constraints. I used a William Optics 132FLT with a x0.8 reducer, QHY9s mono camera, Astronomik 6nm NB filters processed in Astro Pixel Processor using a SHO palette, final processing was finished in Adobe Photoshop. Noise filter in Photoshop was Colormancer.
