M42 - Orion Nebula Setup: - Skywatcher 200pds - EQ5 goto mount - Canon 500d unmodified - Optolong UHC filter Acquisition with Astrophotography Tool: - 100 light frames at 30 seconds (50 minutes worth of exposure) - 30 darks - 30 bias I stacked the images using DSS, and SiriL was used as my main processing software. In SiriL, I used colour calibration and Histogram transformation, as well as changing the black points and tweaking with saturation, stretch and contrast. After this, I noticed that some noise was still prevalent, so I went to GIMP to reduce noise on this image. The Optolong UHC is a great filter that has significant reduced the light pollution in my Bortle 7 backyard, and increased the redness of the M42. With only 50 minutes worth of 30 second exposures, I'm pretty happy with this image. Being a beginner, any tips and feedback are greatly appreciated. Especially on how to remove the red space background. Many Thanks Josh
