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.
I am finishing my free trial of APP, I love it and going to purchase. I have a lot of old data that was originally stacked with DeepSkyStacker and I would like to stack again with APP to see the results.
A good portion of my older data I no longer have the calibration files (darks, flats, bias) as they were deleted to save hard drive space, only saving the master calibration files created with DeepSkyStacker.
My question is it possible to use those master files with APP? I tried a few days ago and received an error message. APP is very new to me and I am not sure of all what the program can do yet. Any help would be greatly appreciated. Thank you.
I'm afraid that won't give you very nice results even if it would work. The way DSS calibrates is likely very different. You could try to use you calibration files you do have (bias, darks maybe) and see how far you can get the old data. Maybe the flats do still work? If not, go without and try the light pollution correction tool. Thanks for buying it, much appreciated!
