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 have had multiple times where I ran into an issue while doing mosaics that popped up when I did the RGB combine. I get an error about my files being too big! Right now I am working on a nice 360 hour multiple panel Cygnus area mosaic and I already know I am going to get nailed with it because I did a partial stack and got hit with that error. Please allow big file sizes and huge pixel mosaics.
This is a problem that did bother me at first, too.
But after three years my mosaic has grown to 141 panels now, the raw fits is - although downsampled to less than 50% of it's size - over 8 GB in filesize. Pixinsight crashes when I want to load this file on my MacStudio. I am at a point where I moght not be able to do proper postprocessing any more with a regular PC or Mac. Imagine if this was not downsampled, APP now needs 1.7 TB free diskspace for the integration-task and has to compute for more than 12 hours with 32 CPU-threads. Otherwise this would bring any computer to it's knees.Â
I now have to finish up my mosaic soon and find ways to process this image.Â
I'm just finishing up one that has 46 panels and is 512 hours and 15 minutes of total exposure. The master lights were about 2 gigapixels when fully integrated. I am running it through downsampling right now to see if APP will combine them or if I have to downsample some more. 36 of the panels were with a QHY600M doing SHO so a total of 108 master lights from that, and then another 10 panels from an FLI PL16083, so a total of 30 master lights from that. My computer can handle it no problem, and would handle it even better if APP would allow the use of more than 64 threads. I have noticed that normilization seems to have a hard time when you get to that size in places.
It would be fun to have a mosaic that is a couple gigapixels, but APP doesn't allow that. I haven't tried combining them in PI yet.
