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 not finding the info I need in Sara Wagner's tutorial on this subject. It is rather old. One thing she does not mention is if any settings are needed in Tab 0? In Tab 1, load my 40 dark frames. In Tab 2 is Integrate set at Automatic acceptable to use and leave the other setting at default? Click Create Masters & Assign to Lights. Results: my Bad Pixel Map looks terrible to me (though I don't really know what is acceptable or normal). Using the ZWO ASI2600MC cooled to -10C. Here is the BPM & Master Dark at the same 100% crop. Do those look OK? Are any other setting needed? Thanks, Carol Santulis

@carsan I'm no expert but your zoomed in attachments look like what I think a master dark and BPM should be. I don't know about that bright star feature that is prominent on your BPM.
I think you should use your regular settings in Tab 0 and all other tabs except not loading any light frames. (I always use the automatic settings in Tab 2). I haven't tried it yet with my ASI2600MMP, but I think you can prepare a long exposure master dark and use it for any lights with shorter exposures with the scaling option enabled in Tab 2 when calibrating light frames.
