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.
Hi.
To calibrate lights just with master flats (created with Sharpcap already bias subtracted) + masterdarkflat is impossibile: popup warning.
Why does flat (or master flat) calibration always need darks (or master dark) to work?
Applying darks (or master dark) to my lights, with asi533, often create more problems than advantages ( https://www.astropixelprocessor.com/community/main-forum/hot-pixel-final-integration-with-black-stripes/ ): so i come to conclusion, after days of experimenting, that using BPM solves that annoying problem of black stripes.
But it's impossible using just BPM: APP wants always darks (or master dark) to calibrate flats (or master flat)...I don't want to use darks...even because asi533 has 0 (zero) ampglow, so no need to use darks that introduce a problem in final stacked image (instead of improving it).
Thanks
I think it's better not to use Sharpcap or any other processor to calibrate your frames. They do things differently compared to APP and APP in this sense is superior with its algorithms to calibrate your data. Same thing for your flats, APP probably has no idea they were already calibrated.
Just load in your data + calibration data and let APP create the masters, that might actually solve your other issue as well... maybe.
