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 have about 600 subs that I'm stacking and only a few of them seem to be rotated in a strange way. I was just wondering if there's an easy way to find out what subs are being rotated?
What do you mean with "strange"? And are you referring to rotation you see in the end-result or with just those separate frames at the start?
@vincent-mod Sorry for the confusion, by strange rotation I mean most of the subs are aligned the same way, but there are a few outliers that are rotated at like 30 degrees or so. It's not a huge deal, but it does cause some lines to form around the edges of the image. You can see what I mean in this image.
I can see faintly, but it looks like all stars are aligned, so that means those frames were actually having a rotation in them from the start, APP aligns them to match the rest. If you add MBB and LNC in tab 6, those lines will likely disappear.
@vincent-mod Right, the images were taking at a slightly different angle APP did what it's supposed to do and aligned them well. I was just wondering if there is a simple way to see what images need to be rotated more than a few degrees and remove them from integration?Â
I will give your suggestion a try though, it sounds like it might not even be an issue, if APP can make them go away. As always, thanks for your help.
There is no need to remove those frames, that would be a waste of data. You can always use MBB and LNC and thing like light pollution correction to get the slight lines removed. And you're most welcome! 🙂
@vincent-mod - searched for and found this thread. You suggestion worked perfectly for me, thank you for posting it. In my case, I had nudged my camera and didn't check any images coming out of it as the earlier ones were fine. Lesson learned. 🙂
For anyone else reading this, I used 1st degree LNC with 3 iterations. I also used advanced mode for normalization.
