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.

Hello,
New user here
and was hoping I could get a bit of help with a problem. Â I've taken mono L, Ha, R,G,B images with the 1600mm Pro and have used APP to calibrate each channel. Â The calibrated LRGB lights look good, but the calibrated Ha lights seem to bright in the middle - They don't look correct. Â My details are as follows:
L - Using 50 Gain, 10 offset and Exposure of 45sec. Darks at 240 sec. @ 50 Gain. Flats & DarkFlats of 50 Gain @ same exposure times using NINA's FlatsWizard.
RGB - Using 50 Gain, 10 offset, and exposure of 60 sec. Darks at 60 sec. @ 50 Gain. Flats & DarkFlats of 50 Gain @ same exposure times using NINA's FlatsWizard.
Ha - Using 139 Gain, 10 offset, and exposure of 240 sec. Darks at 240 sec. @ 139 Gain. Flats & DarkFlats of 139 Gain @ same exposure times using NINA's FlatsWizard.
I was thinking it was related to the flats or dark flats, but when I calibrate the Ha frames using only lights and darks I still get the same issue of a brighter area in the center of the calibrated lights.
Attached are images of the lights (linear) and Lights (Calibrated). Â You can see the brightening of the image center in the calibrated frame. Also included images of my D, DF, F, MDF, and MF for reference. Â

Not sure what I'm doing wrong, I'm very new to this. Â Going a bit crazy here : )
Thanks,

Looks to me as if you have variations in your flats regarding what you're seeing, is that correct? You'd want a flat to be very similar, the same, across the panels as they need to capture the true vignetting profile and any possible dust. Now when not using them and still getting this brighter spot, could you also take out the darks and any other calibration data to test that as well?
@vincent-mod Without the Flats and Darks I don't see the bright spot in the lights alone. Â Do you think the problem is in the original flats? Â I could take a new set of flats and check. Â
Well you mentioned it was still there with the darks added, so removing those has solved the issue? That could point to an issue with the darks in this case.
