Description

So i posted this one a while back but have been working to improve it. Basically started from scratch. This is probably about version 20

Mosaic integration done in Astro Pixel Processor which did a much better job than Photoshop - i lost a fair chunk of the Witch Head in the original registration.

Fixed M42 burnout using standard layer mask HDR technique. The nebula is now resolved down to the Trapezium. I captured the data but struggled to mask it in initially and just left it burnt out.

Natural colour. Used Masked Stretch instead of my venerable ArcsinH. No selective color adjustments. Colour is as shot with custom white balance.

Corrected stellar profiles on the super giants.

Capture :

Shot during the 2019 September Equinox from Tivoli Astro Farm in the Khomas region of Namibia - SQM 22.13

Modified Canon 6D MKII + Sigma Art 105mm @ f/1.4 on Fornax LightTrack II

4 panels each 30 minutes - 60 x 30 second exposures at ISO 1600.

10 x 10 second, 10 x 5 second, 10 x 2 second , 10 x 1 second at ISO 1600 for the Trapezium and M42 core data.

Processing Workflow :

RawTherapee (Flats, defringe, demosaicing)

PixInsight (Alignment, Integration, Correction, SCNR)

Astro Pixel Processor (Mosaic Registration)

PixInsight (Masked Stretch, Starnet++)

Photoshop (Layer Management, Luminance Boost, M42 HDR, Tweaks, Finalisation)
