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,
Â
I have been shooting a mosaic of 6 panels of IC 1805 with an Optolong L-Enhance Filter over a period of time. I managed to create the mosaic with the Ha-OIII color algorithm. Then I wanted to separate in an Ha and an OIII image so I could merge them with a specific RGB palette. So I started to create 6 Ha panels and 6 OIII panels with the intent to create a single Ha Mosaic and a single OIII mosaic and then merge both images. Extracting the first 5 Ha and OIII panels went ok, but the 6th failed to create an Ha image. Then I went to have a look at the quality scores of the different extractions and noticed that the OIII quality scores were in line with Color quality scores, but that the Ha scores were almost opposite to the OIII and Color scores. I have created graphic of all three scores (great that we now have this information btw). Can anyone explain why the Ha data is behaving like this?Â
Â
As a side note): my dew heater was no functioning properly., so when I came back in the morning there was dew on my lens. This may explain why the quality of the overall picture went down, but it only makes me curious why the Ha score then went up???

Hi Tom @tvanpeer,
Thank you very much for sharing this. I think I might know why this happens with the quality score, it has to do with data normalization. Can you check how the quality scores relate if you use another normalization method in 5) Normalize? Probably with additive, it will look more logical.

Hi @mabula-admin,
I would love to try the suggestion you mentioned, but the process already fails at registration, so before normalization.
Hi Tom @tvanpeer,
Oh, there was no mention in your initial post that even registration is not working? Did you enable the cosmic ray/noise reducer in 3) Analyse stars? Maybe that will solve it, APP might think that hot pixels/noise are stars and then registration will fail and the quality scores are not correct since stars are not detected properly. Set the noise reducer in 3) to a value of 10-16 and it should work. If it does not, please let me know.
This issue with locking on to noise instead of stars is on my list to fix.
