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. I have gathered all the OSC panels for the second half of my full Milky Way mosaic, however they are not registering correctly.  I am using exactly the same settings as I used on my Carina to North America mosaic which worked very well
From the attached images you can see that the Vela region by itself registered ok as did the region from Orion to Taurus, but registering all together fails.
Â
I have tried 2.0.0 betas 4 and 13 and both fail quite badly. (13 worse than 4)
I reverted to 1.83.2 and it seems to do a better job but still not right with just a few panes not registering and highly distorted.
Can you suggest what might be going wrong ?Â
Important Settings as follows :
Analyse stars set to 10,000
Mercator projection 40mm / 4.63um pixel size Â
Registration pane changed to somewhere near the middle of the mosaic (reduces distortion of the finished mosaic)
Pattern recognition : triangles
Scale start : 1 / Finish : 15
Dynamic distortion on / same camera and optics off
Other notes : Not all panes are exactly the same size.  Most are 4137x2815 +/- 2 pixels but one is 4121x2796 and one is 4137 x 2837. (from my previous successful Milky Way I found they had to be very similar in size)  Also I think a couple of pane pairs have only about 10% overlap
Any advice would be much appreciated.

Thanks,

That looks like the dynamic distortion correction going wrong. Could you try to see what happens when you switch that off when you combine both regions? I also think you don't need 10.000 stars, try it with 2000 on the latest beta.
 @vincent-mod thanks for the advice.  I ended up going back to basics using the settings from the old mosaic tutorial on this site, then gradually added different processing combinations over a couple of days.  Here is a draft version of the processed results.  I still have much work to do on the doubled-up stars in certain areas and different star sizes between some panes - I consider this quite messy. I will likely capture some more frames with the dual OSC camera rig on pane-pairs where there is small overlap which clearly causes problems. (as well as capturing Hydrogen Alpha & Oiii panels to blend in sometime in the future )

For anyone who is interested here are my settings:
Roughly 7 x 4 mosaic using dual cameras : ASI294MC Pro & Sigma 40mm F/1.4 at F/2.8 plus CentralDS modified Canon 6D & Sigma 85mm F/1.4 at F/2.8
All images per pane integrated with calibration frames (flats / dark flats / darks) and light pollution removed.
All panes then registered & integrated in mosaic mode with the following settings
APP version 2.0.0.beta13
10000_stars analysed
Quadrilaterals Scalestart 5 Scalestop stop 10Â Â Integration reference changed to a panel near the middle
Dynamic distortion on
Same camera and optics on
MBB 20 / LNC 2 iterations 5
Integration Scale 1.0  (1.6GB output TIF file ! )
