New to me workflow:

  • NINA Advanced Sequencer to automate the image capture (dithering while guiding with PHD2)
  • SharpCap Folder Monitor camera to live stack the NINA frames as they came in. 

Next day image processing workflow (Thanks Cuiv, The Lazy Geek!! - Image Processing with Free Software ):

  • ASTAP to create master darks/flats from NINA and scan lights for best images
  • manual review of images to uncheck frames with satellite streaks
  • Siril to stack (manual steps for OSC camera stacking)
  • GraXpert to crop/extract background/denoise
  • Siril to enhance
  • GIMP to touch up and export to web size png
