M42 - THE GREAT ORION NEBULA AND RUNNING MAN - Jan 2021
Ok, this is my final version of this subject for this year. I added another 2 and a half hours of data, to make this a total final exposure of 5 hours.
This is an HDR image created by blending 3 different exposure lengths after stacking and initial processing in Photoshop. It is the first time I've really tried to complete a full HDR image and it think the core of M42 has turned out OK. You can still see detail in the bright Trapezium core region, as well as still seeing fainter details in the outer nebulosity.
I am super happy with the look of this final image, it's muted and has a slightly dreamy colour balance, some will say I've pushed the data too far, but I like it.
Thanks for looking and sharing, comments always welcomed.
Clear skies.
