Horsehead & Orion Dual Narrowband
This is one night of shots with an IDAS NBZ filter, my intent was to use the data for a luminance channel for the RGB data. Altho the narrowband data lacks the pretty colours I don't mind this. Not as happy with the Orion HDR in this version though. Nikon D810A, IDAS NBZ filter, ISO800, 600 seconds (30 seconds for the Orion core HDR), Nikkor 300mm lens at f/3.5, Celestron CGEM2 EQ mount, ZWO guide camera, PHD2 guide software, APT camera control, APP for stacking an initial processing, final processing in Photoshop.
