Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
This is driving me nuts. I've spent a whole day on this. I have LRGBHa frames in lights, flats, darks, flat darks. I'm getting plus signs instead of stars for my calibrated images. What am I doing wrong? I'm using default settings all round and I have the correct frames assigned to the correct filter channel.

That is extremely weird, I've never seen that before. And now, whenever I type that, I do want to check if you're using a FAT32 filesystem where your work directory is located. I don't think that will cause this, but it does cause super strange things, this is because FAT32 has a limit on the file-sizes.
If that's not the reason, something very strange is happening with the calibration data. What happens when you leave out all your calibration data and just stack the lights?
Definitely NTFS. And definitely a calibration problem because the lights on their own stack quite well. Could it be something to do with the fact that the fits header says that the exposure is zero? The actual flats exposure was less than a second and reported as zero. And APP says the ISO is zero. So maybe the flats and dark flats are not matching properly or something.
Yeah there is something really off there, Mabula also has never seen this so we are very interested in the data. Would you be able to upload some calibration frames and lights to our server? Login/password is: appuser
Please create a directory in there called "ddnum-plussigns" and upload in there. Thanks a lot! We will get to the bottom of this.
