Apr 12 2026 APP 2.0.0-beta41 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 has been released which works much better and faster. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more...
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.
Wow, this is the first time I've run across a processing problem with APP and its no fun. I'm trying a stack of 13 of 66 lights and got numerous messages and the final stack was blank. I've attached the series of screens to show what happened. I believe the last beta I tried that worked was Beta38. I tried trashing the old app and re-install Beta41 and these are the results - I have 50GB free space on my drive - all APP settings have been reset to default - Macbook Air on OS26.3.1 (Tahoe).
The first message shows that the integration field of view must be downgraded with a scale of 0.006. That indicates a severe blowing up of the field of view, so something must be way of with registration of the data.Â
Are you trying to register a mosaic? If so, did you change the star amounts in 3) analyse stars and if so which values did you try?Â
If it is a mosaic, with the new registration engine, 1000-2000 will be enough usually. More stars will make it slower and possibly less stable.

Hi @mabula-admin, thank you for responding so quickly. No, this is a simple single session stack of a DSO, needle galaxy using only 13 of 66 images. There was a lot of wind so the session is a total loss but I deselected a few more lights that were heavily blurred or double image and I still get a blank result - I still saw the scale warning but not the others. Some of the pics are reversed to the others because of meridian flip but this is usually not a problem. The warnings I've never seen before with the same computer. I've aways used APP pretty much problem free but now all these warnings and the subject is the same as I have done before. I checked my last session (feb) and it was ok with beta39 so something changed? The OS Â was updated to 26.3.
Hi Astrogee,
Okay, then i suspect that dynamic distortion correction becomes very unstable because of all the blurred and double stars.. Is all okay if you turn off dynamic distortion correction?
Mabula
Turns out that DDC was already turned off, so I turned it ON and re-registered, re-normalized and re-integrated and the result looks good.
Hi @astrogee,
Wow... that is really weird, so with Dynamic Distortion Correction on it works fine? I think that I need to test this dataset then if you are willing to share it? I really need to see why the error occured that you received. Can you upload it here:
https://upload.astropixelprocessor.com/
username: uploadData
password: uploadTestData
Please make a folder with your name and issue like: Astrogee-registration-issue-withoutDDC
And upload the data there and let me know once done 😉
I am glad that at least it works now and you get a great result here !

Hi @mabula-admin, I've uploaded the files. It takes quite some time so I stopped short of sending everything. I think you can repeat the problem with the 13 lights I uploaded. Â Let me know if you would like more files. Thank you for the help!
Hi @astrogee,
I have run the data that you uploaded, the 13 lights indeed are very bad captures, many double stars etc.. But if i process it without DDC all still runs and i do not get errors like yours.
Maybe I did not run it in exactly the same way? At least you got a result with DDC on, right?
What settings did you use to produce the error?Â
