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 it's not one straight photo and i see all the corners...???
Because your subs were not aligned when you were taking the photo's, they all shifted so when APP matches them with each other, they need to be rotated. You can crop the result using the "Batch Modify" button in the Tools tab, draw a box of the part you want to crop out, click "Crop ok" and gone are the corners.

Thank you for your reply.....is the meridian flip the problem ? Because my camera was not shifted in any way....
No, APP will match the subs even when they are upside down, a flip isn't the issue perse (if they are all rotated). Slight shifts are, which could happen after a flip, but whatever the cause they must have happened here otherwise it wouldn't match. Or rotation, which is what it looks like.
edit: Are all subs showing rotation or are the rotations grouped? If grouped, that could be the flip.

Hi NicolasP,
Â
This is a case of field rotation. Do you use an AZ mount or a dobsonian?
Also this occurs when you're mount isn't properly aligned with the celestial pole.

I am using a HEQ5 PRO I thought that I was well polar aligned since I didn't see any drift....
Made a polar alignment with the qhy polemaster

I will have to check my frames again to see .......
Yeap !!!! there was a rotation in some frames .... it seems like my camera setup was unscrewed somehow maybe from a cable.....so i lost about 10 frames.....
Ah, yes unscrewing of parts can be a thing as well, glad you found out!
