June 24 2026 APP 2.0.0-beta46 has been released !
Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.
May 27 2026 APP 2.0.0-beta45 has been released !
Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.
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.
There seems to be a banding issue, or perhaps I am missing a setting, in 2.0.0-beta6 that was not present in 1.083 when processing mosaics.
Using the exact same FITS files and the exact same settings, the beta version presents banding in the final image.
Using the previous version, the image is perfectly smooth and has no defects.
Is there a setting I am missing to prevent this?
Hi David @david,
Thank you very much for reporting this, another user also see this problem, see something is off indeed. Can you share the data on which this occurs so I can test it a.s.a.p. ?
Which settings are you using in 5)Normalize, and which settings for LNC and MBB?
Please upload it here:

Please make a folder with your name and issue description like: David-square-artefactand upload your data there and let me know once done so I can test quickly.

The files are in david-schneider-square-artifact
5) Normalize is: mode regular, method multiply-scale, scale BWMV, neutralize background is checked, scale is 1.0, interpolation method is lanczos-3, apply registration to frames is checked
LNC is LNC Degree: off, LNC iterations: 3
MBB is 25%
I hope this helps!
Hi David @david,
I think that there is no problem here. I get the same results with the old and stable 1.083 versus 2.0.0-beta6 with the same settings in normalization + MBB + LNC.
If I process the mosaic with regular normalization and MBB 10% and LNC 2nd degree I get this when combining the data with RGBSHO in the RGB Combine Tool:
So those banding artefacts are gone then.
Enabling LNC will correct the normalization issue that you see in the mosaic overlap areas. You have the bright nebula in the overlap area and this makes things difficult for normalization as it is in APP. LNC is there to further improve things 🙂

Hello, @mabula-admin !
Thank you for the investigation, and yes, this completely solves the banding!
Thank you again!
