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.
In 1.066 I have been trying to create a BPM but have noticed an error if you select "detect bad columns", process the appropriate images to get a BPM, then uncheck "detect bad column" and reprocess. A severe artefact hangs around as if its related to the previously bad column detection causing the values and BPM to be incorrect.
To recreate:
1. Process Darks, Flats and DarkFlats, selecting create Bad Pixel Map with "detect bad columns" unselected
2. View the BPM
3. Check "detect bad columns" and reprocess
4. View the BPM. For me, this isn't appropriate for my camera
5. Uncheck "detect bad columns" and reprocess
6. Data and image changes show the bad column data interfering
First image is Good/Expected
Second image shows that "detect bad columns" has an adverse affect so I uncheck it and reprocess
Third image should be exactly like the first one - same settings (detect bad columns unchecked) but it is wrong and the values are completely wrong too.
Hi @itarchitectkev,
Thank you for sharing this. I will test this myself using APP 1.068 to see if the issue still exists. I will report back on my findings.

Hi @itarchitectkev,
I have tried to reproduce the issue that you described in APP 1.068. But it all works well I believe.
Perhaps the issue was resolved in the latest versions.
Can you test again and let me know if all is allright in APP 1.068 ?
4. View the BPM. For me, this isn't appropriate for my camera
I don't think your camera suffers from bad columns. Your camera has a rather new CMOS sensor 😉 . The bad columns are mostly only an issue with CCD technology.
Thanks in advance 😉

I can't recreate this on 1.068.
One minor point though - if the option is "*detect* bad columns", then in theory this option shouldn't make any difference if selected or not, but it does. It does affect the BPM. It therefore must be making some wrong decision during it's detection, else it shouldn't be called "detect". Perhaps, "mask bad columns" is more appropriate so it doesn't imply the processing is making a decision?
