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.
Hello,
I have light frames of my HA-OIII colour camera and a friend of me shared his HA and OIII mono fits files.
How can I stack the HA together? I need first to extract HA-OIII, but than it will be a master light file.
Or can select in tab 0 the colour HA and load the HA-OIII in session 1 and HA mono in session 2? And stack them together?Â

I haven't tried this (yet) but it shouldn't be too difficult.
I would start by choosing 'Ha-OIII extract Ha' on tab (0) (assuming its still called that - I'm a bit behind on APP versions).
Don't take APP to integration, just save the calibrated Ha mono files, which you can do on tab 2 or 4. Ideally your friend's files would already be calibrated, otherwise you will need to separately calibrate and save his files (unless you decide to use his data uncalibrated - not ideal but it can work).
Then clear APP and load both sets of data with no calibration files and you should be able to create a combined Ha integration. Depending on which version of APP you are using you might have to uncheck 'same camera and optics' for registration - but I gather the latest APP version does not require this. I would recommend 'local normalization correction' but you might need to experiment with this.
Then you would repeat all this with your OIII and your friend's OIII (I'm assuming you want to use his OIII as well).
This will leave you with a combined Ha integration and a combined OIII integration. Just load these as lights (no calibration), run register, save the registered frames, and you should be ready to do Combine RGB or whatever you like for normal processing of NB mono files.
The only difficulty I can see is you might have to play around with registration options if his pixel scale is very different to yours, or if the star counts are too low.
