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.
Hello,
I am a bit confused which option to choose in the "combine RGB" tool:
- I stacked / integrated my OSC images taken with a L-eXtreme Dual BP filter
- ...extracted Ha and OIII (Ha-OIII extract Ha and Ha-OIII extract OIII).
Â
1. which option to choose (if it matters at all....):
default? or:
Â
Â
2. I can load the Ha and OIII but I cannot load the RGB as RGB, there is no such option, only R or G or B
Â
thanks!
Peter
@peter-s For the RGB image, you need to split that into the separate R, G and B channels. To do so, load the image as a light and then go to tab 2. At the bottom of tab 2 enable "split channels". Then click the "SAVA (calibrated) Light frames" button.
To combine the R, G, B, Ha and OIII channels you can use the RGBHOO formula.
ah okay,
dank u zeer!
Peter
...sorry but a new problem:
After splitting the integration (32 bit float.) into R/G/B I get an error message when combining with the extracted Ha and OIII data:
"the images are not compatible"
- they all should be 32 bit float. (I checked "create 32 bit masters" at 2. and extracted the Ha and OIII from the Master L = integration)
- but they do differ in dimensions:
any idea?

@peter-s Sorry, I forgot to mention that. You will need to load the R, G, B, Ha and OIII files as lights and then do analyze stars and register. That way, APP will align them using the stars in the frames and make sure that all have the same dimensions. I usually also do normalize before I combine the files.
okay - I thought the extracted Ha / OIII would automatically be aligned with the "Original"
but sounds logic 🙂
Peter
