Hello and welcome! I'd like to ask if anyone has experience using light frames with scripts other than the without Darks, Flats, and Biases script. I'm curious if we can use any enhancing scripts to modify our RGB-based images. Is it possible to use these scripts on light frames, or are they only usable with all of the calibration frames as well? If so, it's disappointing if we can't apply these scripts in siril.
Can We Use Ha Scripts Or Hubble Palette Script on Light Frames?

Which scripts are you asking about?
Harry Karamitsos:
Which scripts are you asking about?
I meant the palette scripts like the Hubble or the Osc Ha or Ha extract script.

Hello Szijártó,
I think you are a little confused regarding the Siril scripts. Those scripts are meant to use with stacking RGB images in the first place, calibrated or not, otherwise it won't work with individual files. Some of the scripts that you describe like the one for treating the RGB image without a Dark, or a Flat, etc. means if you don't calibrate the stacking image with one of those calibration frames, the script can try to mimic the lack of those, but they don't do a perfect job as if you actually use the proper calibration frames.
Scripts like the one you mentioned for extracting Ha or the one for Hubble Palette, are simply trash with a fancy name. The one for extracting Ha, what he does is splitting the RGB's channels in individual channels, nothing that cannot be done manually in Siril or other editing software. The Hubble one, uses the same technique but, insted of leaving a mono image from the channel, recombine the RGB with some data manipulation to mimic the colors of an SHO. He just manipulate the data of the color in each channel to give a look of something that is not. Other softwares like the AstroPixelProcessor also have something similar to that, and even in PixInsight you can also fake that too. To achive an Hubble Palette, you need 3 pure and separated channels. Can be done with a mono or a color sensor, but the signal needs to be captured and separated by filter. Other than that is scientifically impossible to be done.
But rebember.. You always need a stacked image to work with them.
I hope I gave you some insight about your question.

So this modifcation scripts in siril or whatever they are, they can be used or applied without any Calibration frames? For example if I only have lights then I could work with these scripts along with light frames. Right? Sorry im just a bit disoriantated on the useage of these scripts. And i was uncertain whether any modification script could be applied to only just light frames.

You can use them without calibration frames, but only in the a stack RGB with the light frames. Only in a stacked image. Not in the individual frames/light frames. And the results won't be the same using those scripts, because for example the script for flats can mimic the vigneting pattern, but cannot do anything regarding the dust spots. Just an example..
Bottom line, I know calibration frames sometimes suck to do, specially if you're using a DSLR.. but they need to be done. There's no magic solution to work things around.
