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.
Hello,
I've just started using APP and was wondering what would be the workflow to stack frames (light, darks and flats) gathered in multiple night of the same object and same equipment but different gain values.
Previously I was using DeepSkyStacker which allowed me to make groups (per night sessions) and stack all together into a single TIF file.
Any thought would be highly appreciated. Thanks.

Hi Jairo,
APP has the option to process data from multiple sessions. Have a look at the 1) LOAD tab. At the top you can select "Multi-Session processing". Then when you load the lights, APP will ask you for which session they are.

Hello Jairo,
As Wouter says.
There is also another way. You can also calibrate each session separately and save the calibrated subs. Do that every time you have gathered exposure time for a subject (using the appropriate darks, flats and flatdarks and BPM). In due time you will have a collection of calibrated subs and when you want to integrate, you simply load all the calibrated subs as lights, tweak the integration parameters to your liking and off you go.
This is the way I do it, because there can a lot of time between sessions due to bad weather and calibrating per session, just after the time of capture, makes it easier for me to remember which flat belongs to what session as it is still fresh in my memory at that time. I also perfom an integration whenever I have added a new session, just to see if and how much it is going in the right direction and to evaluate if I am at the point of enough-is-enough.Â
In the end, I delete the original subs and keep the calibrated ones. If you then want to add exposure time much later, say next season, it is a simple matter of making calibrated subs of the new exposures and throw them with the calibrated subs you already had in APP to integrate.
Regards,
Anne

I agree with Anne - I used to wait to calibrate all my data when I had accumulated all the data I wanted to use in my integration, and it took a long time and was tedious finding all the proper flat frames to use for multiple sessions.
Now I calibrate the day after acquiring the data and save the calibrated frames. This greatly speeds up the integration process when the time comes!
Cheers,
Rowland
