This bicolor image of the Orion constellation was created using images taken through an L-Enhance dual narrowband filter. The image uses the HOO color palette with R=Ha, G=OIII, and B=OIII.
Imaged with 50mm Nikon at F/4, Optolong Lenhance dual narrowband filter (mounted to the front of the lens with a step ring), and full spectrum modified Nikon D5300.
Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Extracted red/green/blue channels using BatchChannelExtraction script. Registered and stacked using StarAlighment and Integration. Total integration time of ~1 hours using 43 subs at ISO1600x90 sec. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, masked stretch, TGVDenoise for noise reduction, and morphological transformation. HOO image generated using SHO-AIP script with luminance using Ha data.
