Description

Over the past few weeks, I revisited the perrenial favorite Orion Nebula Complex with my new imaging setup consisting of a WO GT81 APO refractor and full-spectrum modified Nikon D5300 DSLR. I also took a crack at the HDRC (HDR composition) process in PixInsight and combined images with 30s, 60s, and 120s exposures. Definitely my best Orion image to date, but I plan to revisit this target to add some additional short exposure data to see if I can pull out the Trapezium and then add in some H-alpha data to see where that takes things...

M42/M43/Running Man Nebulas imaged on December 30, 2018, January 6 and 10, 2019 with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer and full spectrum modified Nikon D5300. Stacked using PI for a total integration time of ~3 hours using 120 sec, 60 sec, and 30 sec subs at ISO 200. Subtracted darks, bias, and flats. Stacked subs at each exposure using Batch Pre-Processing (BPP) script. Light stacks at each exposure cropped and ABE applied, then registered and combined using HRDC. Post-processed in Pixinsight: Cropped, gradient removal with DBE, Background Neutralization, Color Calibration, SCNR, stretched using Histogram Transformation Tool, Curves Transformation, HDR Multiscale Transform, Morphological Transformation, ACDNR noise reduction, and Color Saturation adjustment.
