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.
Hi Mabula,
When normalising is there a thresshold in quality to know when it's better not to use some low quality frames for stacking?
I supose eg quality stacking has it's limits too?Â
Thanks
Cheers

Hi Guido,
No not really, it really depends on the particular dataset and it's size and guidelines are hard to formulate I feel in this case.
For this purpose, I developed the quality weight setting, if frames are really bad when compared to others, they will have very low weight in the integration and therefore won't visually affect star size and roundness in the integration, but they will still help in lowering noise in the sky background.
If you have bad frames due to clouds/foginess/ bad transparancy/seeing, this usually can be seen from star density dropping with increased SNR (SNR is easily fooled by clouds/ foginess) and increased FWHM. From the details of all of your frames, you can usually remove them pretty quickly, if you scan for lower star density in combination with higher SNR in my experience. And frames with clouds/foginess are best left out, so do scan for them using the details of the frames.
