IC 1396 (Elephant's Trunk Nebula) in Cepheus

June 5, 2022

I captured another four hours of data last night, this time in OIII, and here's the processed version with combined Hydrogen-alpha and Oxygen 3 data. Oxygen is in blue (~504nm) and Ha (~656nm) is in red. Imaging Notes: 64 x 240 second subs in Hydrogen-alpha, 72 x 240 second subs in OIII, stacked in DSS, over 9 hours of data. Gear: William Optics SpaceCat51 Apo Refractor, ZWO ASI1600MM-Pro mono camera, Antlia Pro 3nm Ha, OIII filters, Sky-Watcher EQ6R Pro equatorial mount.
