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. Before I release it, I will make sure that everything is working properly and then I will release it.
I have a 2-panel LRGB mosaic that is registering fine but one panel looks quite washed out compared with the other.
Set up each session as a different panel and I set up 1st degree and 4th degree LNC hoping that would even things out.
My normalization is set to Advanced/multiply-scale/BMMV with neutralize background off.
Anything else I should try to get the panels of the two images to better match up?
Thanks!

So how does that panel look like when you integrate it first (before making the mosaic)? Is it quite different in quality somehow? What I usually do is to correct light pollution etc. per panel first and then I make the mosaic. Seems to work quite nicely, LNC then takes care of the rest.
here you can see the mosaic and then the session 1 and 2 individually, just with an stf in pixinsight
Oh that looks very strange. Can you give some details on how you made the mosaic and what the input data exactly is? Is it raw files or did you already process them somehow?
Would be nice to have the 2 panels as well, I can have a quick look then as to what might be up.
Sure thing - should I share with your fb acct or is there a way to DM links to the raw file?
You can upload it to our server, or.. since it's 2 panels; maybe share a wetransfer and e-mail it to vincent@astropixelprocessor.com. Whatever works best for you, if you want to upload to our server;
Go to https://upload.astropixelprocessor.com and use upload2 as username and upload2 as password.
Create a directory named “mr1337-mosaic” and upload in there. Thank you!
Sent along some files for reference. and here are the rest of my settings. Let me know if you need any more detail:

Ok, thanks for the data, working on it now. Looking at the mosaic, it seems like you didn't use outlier rejection for the panels, is that correct? Or at least I'm still seeing satellite trails. What calibration data do you use? Did you use LNC also for creating the panels? If not, that may already improve things.
Furthermore, I didn't get the washed out effect, but the only difference is that I turned off "same camera/optics" and switched off dynamic correction (didn't work switched on in this case, which can happen if the data doesn't need too much correction). The registration RMS wasn't great though, so I'm wondering also how you made the mosaic, what kind of overlap etc?
Overlap is around 10%
Tried manually using the outlier rejection and that helped balance the frames out a great deal. I saw registration issues after doing that, specifically on the right side. After reintegrating with dynamic correction off I still saw some issues and went in and removed a few jumpy frames from the lights. After doing that and going back and turning on dynamic correction again I got a really nice mosaic. I think the only difference now is a few frames that had moved a bit and not using the automatic integration option. I guess that will be my go-to now is just to make sure I don't use that automatic feature for mosaics since that is pretty much the only change I ended up making in the end.
Ok, interesting still as normally that would work pretty much automatically. But, good to see you got it working nicely!
