Is there a way to apply Asinh to sequence - for Comet

Software Siril
1

I was trying to follow the instructions on the Comet tutorial Siril - Working with Comets but what I find is that just applying the Hist transformation does not bring out the green colour. So I am ending up with less colourful comet on the sequence.
But the author has managed to get a nice green colour. Can someone point out what I may have got wrong?

it’s difficult to obtain a result with only histogram transformation, often color calibration or color boosting is needed, depending on the sensibility of the camera and the filters used among others.
Siril is not able to apply the asinh operation to a sequence, but it could be done in a script like that Siril - Advanced Siril scripting with bash or DOS

Thanks Vincent.

Hi,

As explained at the end of this section Siril - Working with Comets, you can export the images as a series of tiff and further batch process then with another software. The bright green color shown in some images of the tutorial was obtained by boosting saturation in ser player for instance.
