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 new to mosaics having completed my first one this morning. At first glance the results didn't look too bad, then I looked closer. The subject was the Rosette Nebula in Ha and Oiii using an Esprit 150 and Atik 16200 Mono with Astronomik filters. Upon close inspection, there are tiny lines or rows of dots that appear throughout both channels. I do not see such artifacts, or at least I can't recognize them, in the individual subs. Any ideas on what might cause this? The two channels can be found in the DropBox folder linked below.
Thanks!

@dandra Hi David,
Such lines get caused by a small drift during guiding combined with APP not completely being able to get rid of all hot pixels. Did you apply any darks while processing? If yes, were they taken at the same gain, offset and temperature as the lights? If also yes then you may want to play with kappa low and kappa high for the Master Dark in tab 2 to make sure that the hot pixels get rejected better.
Thanks, Wouter! I re-shot my darks (they were several months old) and adjusted the kappa values. That took care of almost all of the artifacts! David
