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 using APP for several years now, and this is a new one. I collected these data over the past couple of nights. All the subs are clean and normal. All three individual channel stacks look normal when processed. However, when I attempt to integrate them in the SHO Hubble Palette this is the result:
 If I cut out the Ha data channel it looks like this, so the issue is with the Ha data. I've never seen this before, and no matter what I do with settings it doesn't help.
 I calibrated with Dark, Flat, Dark Flat and master bias.
This is the Ha data stack:
Thoughts?
Thanks in advance,
Eric
I did a process with Beta 23 and didn't use any calibration files and the data is normal. Will try a stack now with calibration files to see if they are the problem.
My Ha Flats or Dark Flats are the source of the problem. I don't know what the problem is, but it seems to only affect the Ha data. I'll recapture flats and see what shakes out.
It was not the calibration files. I changed the combine RGB setting from multiply-scale to add-scale and it works normally. That's 3 hours of my life I'll never get back...
Hi Eric @flywaldo,
Thank you very much for sharing this, sometimes this can occur if the data channels differ a lot in quality, especially the normalization with scale can cause this. But it will be good if I can analyse this to see if I can improve things here.
Maybe you can upload those 3 stacks here:

Please make a folder with your name and issue and let me know once uploaded.

Mabula,

The three stacks are uploaded to the folder with my name. I'm working on processing it now, having difficulty with star color correction - it skews way into green and I can't get it back properly. It's not a lot of data, but the detail looks good so far at least.

Thank you!

Hi Eric @flywaldo,
Thank you for your upload, I will have a look at your data and issue in the coming days and will get back to you 😉

Hi Eric @flywaldo,
Thank you very much for reporting this issue with multiply-scale normalization in the RGB Combine Tool, your H-alpha data triggered a rare bug. I have found and fixed the problem though 😉
The fix will be included in 2.0.0-beta26 😉
Mabula
That's great, I'm glad that I was able to contribute to the development of APP in this way!
