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.
Can you successfully mix FITS Light frames with Camera RAW Calibration frames?
@jaximages Assuming that with camera RAW frames you mean CR2 or similar, if the images are shot with the same acquisition software and version then it shouldn't be a problem. But it still could be so unfortunately you'll have to try and see.Â
Due to a slight mix up, i captured all my Light frames as FITS files in the ZWO ASIAir and all my calibration frames as NEF RAW files on my Nikon. I a  running a test right  now, MTF.
It looks like you CAN NOT mix FITS files with RAW files. i re-ran my Calibration frames against a small set of RAW Lights anti all worked as expected.Â
Thanks, that's good to know.Â
