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.
Hi Mabula:
My workflow for the last year has been to open my RAW files (NEFs) in Adobe Camera Raw, do some minor processing to reduce highlights to prevent stars from blowing out, do the lens corrections and vignetting removal, and then save them as 16-bit TIFFs, and finally stack them in Deep Sky Stacker and save as a 16-bit TIFF to be processed in Photoshop.
Now that I am using APP, would I get a better end result in terms colours and other things if I stacked the original unprocessed RAW files in APP rather than stacking these TIFFs?
Thanks,
Rudy
Yes. 🙂 It's always best to start with the least processed raw data.
Great! Thanks, I will do that from now on.
Cheers,
Rudy

Hi Rudy,
Yes, like Vincent indicated, it will be much better if you work with the raw images.
Processing steps like
- data calibration,
- data normalisation,
- average/median integration,
- outlier rejection during integration
- light pollution/gradient removal
- background calibration
- star color calibration
all work the most optimal if the data is as linear as possible, that means straight from your camera's sensor 😉
If you convert your raws in photoshop to TIFFs, then the TIFFs will be highly non-linear due to several steps in the raw conversion of raw files to images meant for normal photography. I will explain this in more detail in your other topic:
Kind regards,
Mabula
Excellent question, I upgraded it to a sticky as well 😉
Everyone that reads this, might want to read this as well, because it's directly related:

Following excellent information provided by Mark Shelly, Rudy Pol and Roger N. Clarke, APP will soon be upgraded with color preserving stretching and the possibility to use the color matrix conversion in DSLR processing. Then there will be no need to use an external RAW processor for better colors.

Hi Mabula,
This is fabulous! I can hardly wait!
Thank you in advance for doing this,
Rudy
As soon as .dng support is available I definitely want to try it. I was tempted to go ahead and get it and try using tif files sicne i figured out how to convert from .dng to 16 bit tif files.
