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 seem to have a problem with my flats in the sense that they do not correct vignetting or take out some artifacts in the optical train (that don't seem to be dust bunnies). I image using a 300mm lens and a full spectrum modded Pentax K-5. I have taken the calibration frames (50 bias, 20 darks and 20 flats) and the flats (see attachment) also show the vignetting and artifacts, but don't remove these from the final stacked image. Does anyone know what may cause this? I will take the flats in the morning with the white t-shirt method and the camera in Av mode using the same ISO and no changes to the optical train.
Â
Many thanks in advance,
Hans
Take a look at the file name after you do the calibration step. If it only shows CA next to the name it's not applying ANY calibration frames. Recently I've been having this issue with APP and I don't know how to fix it.Â
