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.  Before I release it, I will make sure that everything is working properly and then I will release it.

Hello!

I have illustrated my problem in the picture below. After calibrating the star colors, the colors are completely desaturated and the picture gets a greenish tint.

 

colorcast

 

As you can see in the example picture the colors look much better before the calibration. Do you have an idea what went wrong?

Is it possible to skip the "calibrate star color" step?

 

I have loaded the stack into a drive folder for you. You can try it yourself 🙂

Hi Gernot,

 

There is a small shift ( i think du the Optolong filter) to the green side, if you open the star calibration tool you need to move the Magenta / green constant slider to the - this will move the green cast to the magenta side ( from green to white).

See screenshot for the settings i used.

I did make in a few minutes this version of you're data, maybe a bit to the red / magenta side but i did it on a small laptop screen.

 

Hope this helps,

Hi,

An alternative method is to apply HSL selective color after calibrate star colors. In you case, I try remove cyan from green, reduce cyan in yellow, remove red and yellow from cyan, and increase magenta in red. Just play around with these colors!

Cheers,

Kijja
