Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and itĀ will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. 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 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
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.
First go with app in a while and its not ended good, all was well up to the integration, after integration it left strange black marks, I thought at first it was specks on my screen, made a few changes and re run but app then crashes, so all settings etc lost, so frustrating. I don't get to do much processing as I'm usually fairly busy but its soooo annoying that something that should be simple with app just doesn't seem to work for me.
aftefacts dont seem to show up here

Do you have an example of the strange marks? I'm not sure what would cause them to be honest from your description. Which version of APP are you using?
Sorry its been a while, but I'll upload to dropbox, I have sent @mabula a dropbox link.
Hi Tony @tonymacc (& Vincent @vincent-mod),
I am finally looking at your data that you sent me using wetransfer. I did download it. Unfortunately, the downloaded data is completely corrupt, all fits frames are broken. I think something went wrong with the download while I was in London for AstroFestā¦
Can you send it again using either wetransfer or directly uploading it to our server:

Make a folder with your name and let me know once uploaded 😉
I looked at your image that you posted on our forum. I think you mean black spots like this are the problem? You need to zoom in to see it properly:
That would indicate a data calibration issue. There are several possible causes:
- Are you using a Bad Pixel Map? Are you subtracting a MasterDark? Hot pixels in the MasterDark could cause this to happen. A proper Bad Pixel Map would fix it.
- Another cause could be cosmic rays in your MasterDark. Do you see Cosmic Rays in your MasterDark? If so, create your MasterDark with outlier rejection enabled to remove these artefacts from the Master. If you donāt remove these, they will create black holes in your calibrated data just like this.

Kind regards,

Hi Mabula,
Yes I can send it again when I am back home. It's strange about those spots as this is an image I have already done in app previously using the exact same subs etc! but just wanted to see if the newer 1.075 version made any difference, I dont think I done anything different to before.
Regards,
Tony

Dear Tony,
I think the most likely cause is that there a cosmic rays in your masterdark and they create holes in the data when calibrating the light frames. Can you check?

Thanks, will look, but on another note these are the exact same subs and darks etc! used on the older 1.074 version with no issues, but I will go back and have another go.
