Description

This bicolor image of the region around the Flaming Star Nebulawas created using images taken through an STC Duo Narrowband Clip Filter. The image uses the HOO color palette with R=Ha, G=OIII, and B=OIII.

Imaged with 85mm/F1.4 Rokinon at F/2, STC Duo Narrowband Clip Filter, 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. R, G, & B channels registered and stacked independently using StarAlighment and Integration. R channel data gives the Ha image. Averaged G & B channels using Pixelmath to generate OIII image. Total integration time of ~3 hours using 48 subs at ISO200x240 sec. R and Average of G+B channels individually post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, stretched using masked stretch, Curves Transformation, TGVDenoise for noise reduction, HDR transform, Local histogram transform, morphological transform to shrink stars. HOO image generated using SHO-AIP script with luminance using Ha data.
