M42 - The Orion Nebula

Equipment details:

  • Mount: OpenAstroMount by OpenAstroTech
  • Lens: Sony 200-600 @ 600mm f/7.1
  • Camera: Sony A7R III
  • Guidescope: OpenAstroGuider (50mm, fl=163) by OpenAstroTech
  • Guide Camera: SVBONY SV305m Pro
  • Imaging Computer: ROCKPro64 running INDIGO server

Acquisition & Processing:

  • Imaged and Guided/Dithered in Ain Imager
  • 420x30s lights, 40 darks, 100 flats, 100 biases, 100 dark-flats over two nights
  • Prepared data and stacked in SiriLic
  • Background extraction, photometric color calibration, generalized hyperbolic stretch transform, and StarNet++ in SiriLic
  • Adjusted curves, enhanced saturation of the nebula and recombined with star mask in GIMP, desaturated and denoised background

This is my first time doing a multi-night image, and my first time using SiriLic to configure a Siril script. Any tips there would be helpful. Suggestions for improvement or any other form of constructive criticism are welcome!
