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 everybody,
I would like to reduce the impact of the flats to my stacked image.
As you see the mild yello circle in the middle of the stacked image comes from the flat.
DeepSkyStacker is stacking these data in a more "mild" way, so that I can say that it would be very helpful to reduce the intensity of the flat correction.
Is there a way to reduce the "influence" of the flats?
Thank you and
greetings from Peter

@sternefueralle There is no way to influence the way the flats are applied to the lights in APP. I am afraid that if you get such artifacts after applying the flats, that the flats are open for improvement. So you may want to review the way you take the flats in order to get rid of this effect.
@wvreeven Thank you for your answer. I worked it out and found an improvement, that helps me with my flats...sorra, it's my fault. CU
I made new flats with an exposure time around 4.6 secs and added dark flats for the first time. Now the master flat is more equal. Not so intense... this works.Â
@sternefueralle Yes, creating proper flats and using dark flats or bias frames to calibrate them is the preferred way. In my experience dark flats work better with modern CMOS cameras. Glad to read that you sorted out this issue.
It is strange, that this occurred suddenly. The correction frames I usually used worked very fine. But suddenly, I can not really say when, it behaved strange, as I showed. So I was confused and did bout know where the problem comes from, or better, how to solve... happy to have solved another problem in astrophotography...
