The only lengthy parts were the GraXPert steps and only because my computer is old and does not gave a modern graphics card so the steps take a long time. I just start a step and walk away for a while until it finishes and then come back and do the next step. My actual tone doing things at my computer is only about 5 or 10 minutes. If I add the time I’m waiting for my computer to do the long steps. Perhaps 30 or 45 minutes total. I do have plans to upgrade my computer later this year.
Congratulations! 10 min editing time is pretty impressive (to me). I wonder is it an average time for processing all types of DSO images? I do agree with BrickInTheSky that stretching (curve, level) could be the most critical step of editing, and thus it deserves taking a little more time to achieve a favorable result. Thanks for sharing.
