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'm getting Satallites across light frames from time to time. Should I be eliminating those frames from the Light files list before processing them, or does the Satallite line get eliminated during the integration or calibration process? Here is an example of a fits file with a Satallite line going across it attached.

It depends upon the algorithm you are using during integration. If you use a simple "average" stacking mode for your lights, then the satellite track will leave some faint "residue" behind, so you should remove that light frame. If, however, you are using some form of Kappa-Sigma clipping for your stacking mode (recommended), then the pixels along the satellite track will be outliers and removed. Any "residue" should be negligible or non-existent. Run some experiments with both stacking modes and see for yourself. 🙂
Hope that helps.
And APP should take care of this for you automatically in most cases. Under tab 6) INTEGRATE, if you leave "integrate" set to "automatic" it will integrate your lights using either the "median" method (for less than 20 light frames) or the "average" method with "sigma rejection" (for 20+ light frames). Both methods will remove the satellite track (but I suspect the "average" method using "sigma rejection" will be superior). If you hover your mouse over the drop-down boxes in the INTEGRATE panel, you can get more help. Again, experiment with the various options. It's the best way to climb the learning curve. Good luck!
In automatic mode, the "best" algorithm is chosen based on the amount of frames. But, if there is residue, you can try to set the algorithm yourself, like @rhalbers3 mentions, and lower the kappa values to get a stronger rejection.
Having more frames will also help with rejection.
