MAY 4 2026: APP 2.0.0-beta44 has been released !
New improved internal memory controls should now work on all computers
May 1 2026: APP 2.0.0-beta43 has been released !
Improved internal memory controls (much more stable and faster on big datasets), fixed CPU image viewer, fixed Narrowband extraction demosaic algortihms.
Apr 29 2026 APP 2.0.0-beta42 has been released !
New improved Normalization engine, Fixed random crashes in integration, fixed RGB Combine & Calibrate Star Colors, fixed Narrowband extraction algorithms, new development platform with performance gains, bug fixes in the tools, etc...
Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options
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.
Hi,
i´ll have a nice data set of a TwoPanel Mosaic with a 510mm Refractor. It´s LRGB Data with one and the same CCD Camera/Flats/Darks/Bias etc.
Can i do the processing in one go? Saw Mabulas Tutorial, but as this data Sets are so differently, he might be first calibrate all on its own. If,like in my case, the Data Set is consistent, would it a be possible to calibrate and stack it in one go in Mosaic Mode?
CS Frank
Yes it is possible to do that. However, star analysis and registration may take a long time depending on the number of lights. In my experience, stacking the subs separately and then creating the mosaic is much faster but it requires more manual intervention.
Wouter
Thank you Wouter,
yes, its working now and it seems to take a lot of time and processing power. In between i got a black screen, i think the Laptop overheated a bit.
I was confused because i thought it might be clever to reduce the data in a Multisession Set. So Two Sets of Lights, one Set of Calibration Frames. But after Star Analysis, APP choosed just one Frame as Reeference. This made me a bit unsecure.
So if i do it seperately, i should do that as well in Single Mode for each Data Set?
Cs Frank
Hello Astrophotocologne, with a two-panel mosaic you can calibrate everything at once and then stacken.
The registration should be done in normal mode.
For star analysis, set the value to 2000-2500, depending on the overlap of the panels.
Alternatively, calibrate and stack each panel to a session. Then process the stacked panels in mosaic mode.
Best regards Henry
Hell Henry,
thank you,well that Link says it all. I thought i´m treating my data very well if i fully run the whole show in mosaic mode, but this is not the case i see now 🙂
Thank you!

So if i do it seperately, i should do that as well in Single Mode for each Data Set?
That depends on your data but from what you described before I think yes.
Wouter
Yes, integrating the panels of the mosaic first and then creating the mosaic is better. This is because when using only all subs, the statistics behind this algorithm will go through the roof making it very complex and taking a long time.
Thanks for all the answers,
now i´ve did a run through as you recommended and it worked perfectly fine and pretty fast. Its just a TwoPanelMosaic, so the next Goal ist to create larger Mosaics. With Two Panels it might be even work if i don´t use the Mosaic Mode? I think Mabula mentioned this in one of his Videos!?
CS Frank
It probably will yes, if the overlap is ok. Never really used it in that way though myself, clearly separated panels I already call a mosaic. I'm not sure, but using the mosaic settings may give you beter registration precision. You can check if this is the case by comparing the RMS values in the table.
