Tempted by the examples published here, in which some great photographers showed stacks composed of thousand of frames, I’ve tried my humble experiment on this field. I’ve taken “only” 730 frames of M1 with 10sec exposition time. Obviously 730x10 frames are not enough to get a complete clear image, but the image is comparable with other 2h images that I’ve taken from the same object with more traditional exposition times.
But, I’m not here to talk about my pictures, but to talk about how powerful is SiriL. I don’t know if you are aware that SiriL could be used as a command line program, without UI, to run scripts.
I’ve used this feature, combined with bash scripting, to perform an incremental stack of the 730 frames. I’ve stacked first 2 images, then 3, then 4… until a last stack of 730 frames. So at the end I’ve 730 frames. Each frame is the result of one stack that goes from 1 image to 730. I’ve combined them in sequence (again, using SiriL) into a SER file to “see” how signal emerges from a sea of noise.
Without SiriL this video of stacks would not have been possible, so thank you very much to keep providing scripting capable tools, on this days of prevalent UI tools
