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.
Why is the integrated image have distortion like fisheye lens, as opposed to just being a normal rectangular image? I believe I used all the default settings for star analysis and registration, with "distortion correction" and "same camera and optics" checked.
Hi Maxim @mseningmail-com,
In this case, distortion correction is not needed and should be turned off, you trigger a bug in our registration engine. The optical distortion correction can have a mathematical instability on data that really does not need it. So turn it off and all should be okay 😉
We will fix this going forward 😉

Thanks, @mabula-admin, I already figured it out. I wonder if it's related to stars with coma and minor tilt at the edges so that APP computes PSF of the edge stars and tries to correct for it as if it were a fisheye lens or something with astigmatism. Thanks anyway.
