I pose this question, hoping it is not stupid.
Is it possible that integrated Starnet++ can be used to eliminate stars on an entire sequence of cometary images in a single step?
This would then allow the images of the comet alone to be registered and stacked without the artefacts (streaked stars) that - I saw - are not easily erased with normal Siril processing.
Thanks, I think I have it now. Very faint tail so playing around with the stacking Methods and Sigma’s to see which one renders the best starting place. At heavy stretch there’s still star trails from Starnet but I know that’s the case on all the star removals regards of the type of image.
