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 been working on a 2-panel mosaic of the Rho Ophiucus Cloud Complex using APP (version 183). I wasn't happy with the overlap and then realized my flats were not of the best quality. So I reshot my flats and then started a fresh copy of APP, so I had to reload all files and tweak the following options from the default settings.
- 1) Load
- Uncheck Multi-channel/filter processing
- Load lights for panel 1 as session 1
- Load lights for panel 2 as session 2
- Load flats for all sessions
- Load darks for all sessions
- Load biases for all sessions
- 4) Register
- Set scale stop to 10
- Enable Dynamic Distortion Correction
- Do not disable same camera/options
- Set registration mode to mosaic
- 6) Integrate
- enable 1-degree LNC, 3 iterations
- enable MBB at 10%
And then go by pressing integrate....
Initially, I was getting the stack that appears on the left (repeatedly), but after swapping out flat files, and I deleted all intermediate (master dark etc) files for a clean stacking, I got the oddly distorted stack that's on the right, repeatedly.
What am I missing, or doing wrong?
Thanks!

Hi Mike,
A few suggestions: Try setting Normalize to Advanced and set Integrate mode to Normal. Increase # stars in Analyze Stars to over 3000.
A better procedure might be to integrate the 2 panels separately. Then load those integrations as light frames in a new APP run to create the mosaic.

I see the Advanced setting under the Normalize tab, but no Normal until the mode near the top of the integrate tab (there's automatic, average, median, and maximum).
I forgot to include on my steps, on 6) Integrate, I have "Integrate per sesson and all" selected. Wouldn't that be the same as integrating the 2 panels separately?
Thanks for the suggestions!
My mistake; I meant to say use Normal instead of Mosaic in the Registration tab. In an earlier post (I think by Mabula) there is a discussion that the Normal setting often works better or faster for mosaics. There was also a post that integrating the panels separately can yield better results; at least that is what I have in my APP mosaic notes. I will try to run down those posts and let you know if I find them.
Thanks for the discussion links!
