UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
Encounter of difficulties in calibrating the color of the stars. I can not understand from time to time how to adjust.
I have to add more hours, but gradually I like to see how the photo evolves.

Hi Paolo,
Is this broadband data, it looks more like you used a narrow-band filter is that correct? If so, you can't really calibrate using the star color tool. That requires broadband data.
@vincent-mod
I use l-enhance and i confirm @vincent-mod's words: it's difficult to obtain a good color star calibration. But i managed it to work sometimes with l-enhance, even if i have to tweak parameters for 20 minutes in an opposite way as mabula explained in that tutorial... Â
Sorry I had not seen the update of the post. But I never quite understand how to fix colors.
I use the L-Enhance filter
@vincent-mod
Thanks it was for knowing where I was wrong.
So it's clear to you now or do you still need further assistance, happy to help..
For narrow-band data, it's not possible to perform color calibration automatically. This is because APP uses the broadband data belonging to stars in their main phase of life. So you would need similar broadband data for it to work. Narrow band data is more down to the photographer on how to show this. You can use the real look of H-alpha for instance which is more pink, but many prefer red for instance.
Ok thanks 🙂
