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.
When I open remove light pollution the screenshot shows what I see - a pure white image. I don't know how to resolve this. It is the first time such a result has appeared for me. Â
What should I do?
Â
EDIT: I get the same result when opening 'correct vignetting' and 'calibrate background' in addition to 'remove light pollution.' If I simply open the stacked integration the image looks fine. If I click 'neutralize-BG' on the right side, the image goes all white. What settings do I need to change? Since I have subscribed this is the first time I have seen this behavior. Same camera and workflow.
Â
What camera are you using and if it's a regular astro-cam, what is the offset you used?
I am using the Asi533mc pro camera. I also use the AsiAir Pro and am not able to adjust the offset. Â
Â
Just so you know.
Â
Ah, so can you check the FITS header to see what the offset is at? Should be somewhere in that window left from the image.
Hi,
When I look at the histogram on your screen-shot above, I see what looks like a single column of what would be very cold dark pixels at the very left hand side then a gap of about 80% of the histogram space before seeing all the values piled up at the right hand side.
I would guess that you can make your data more visible by adjusting the B and/or ST filters.
I suggest that something has gone slightly amiss during Calibration that these cold pixels have not been detected and removed. Maybe you can try adjusting the Cosmetic Correction / Cold Column Kappa values on the Calibration tab to get a better result.  As I recall the Christian Sasse video shows you how to view what effect changing these values has on your subs.
Regards
Mike

Well spotted Mike, that might contribute.
