Jan 31 2026: APP 2.0.0-beta40 will soon be released with many fixes especially for Linux, upgraded development platform and 10-20% performance boost !
Jan 15 2026: FIXED LICENSE SERVER VPN Tunnel issue
 The issue could have prevented APP to start when using a VPN tunnel or another complicated network configuration, like using APP on a remote computer on a different continent. This issue is fixed now and APP should start normally.
Jan 04 2026: 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. Unfortunately, Mabula was struck by a severe flu virus in the past couple of weeks and thus could not work. He is getting much better now and he has resumed work to release 2.0.0 as soon as possible. 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.
Nov 28 2025:Â APP 2.0.0-beta39 has been released !
Hello App members,
Â
From the Netherlands here i am busy with a mosaic project of the Orion nebula, horse and the 3 stars of the orion constellation? I want to try that out, but i have some questions.
I use my William optics GT81 with x0.8 and my ASI 294 MC pro on mt EQ6R pro mount.
About the mosaic that got 6 panels, each of them i did 15x180s with L-pro filter for RGB colours and 18 for HA,OII with my L-enhance dualband filter.
Â
Now is my question is this enough? Because some of them got satellite trials and the Orion constellations is almost behind the house of my neighbours. I got a FOV from the NE until the SW. And Orion is now at 1930PM in the south and getting closer to the SW.Â
This week will be sad in the Netherlands, i hope to get some clear skies here next week for each panel for 25 frames with L-enhance.
Â
Is there a tutorail of APP mosaic?
And every help or tip will be awesome. In english or dutch, doesn't matter.
Â
Hoi Stefan, ik zal even antwoorden in zowel Nederlands als Engels (voor de andere gebruikers);
- 15 frames per paneel kan prima, echter is dat waarschijnlijk te weinig om goede satelliet sporen weg te poetsen. Zal je moeten proberen, misschien met wat agressievere rejection parameters.
- De totale FOV lijkt wat breed, dat kan behoorlijk lastig zijn soms afhankelijk van de kwaliteit van de data en de projectie.
- Er is een wat ouder voorbeeld van mozaiek processing alhier: https://www.astropixelprocessor.com/mosaic-tutorial-milky-way-to-rho-ophiuchi-by-mabula/
- Een handleiding wordt aan gewerkt met als doel deze in de 2.0 stable release uit te brengen.
English:
- 15 frames per panel is fine, but that is probably too little to remove good satellite traces. You have to try maybe with more aggressive rejection parameters.
- The total FOV seems a bit wide, which can be quite difficult at times depending on the quality of the data and the projection.
- There is a somewhat older example of mosaic processing here: https://www.astropixelprocessor.com/mosaic-tutorial-milky-way-to-rho-ophiuchi-by-mabula/
- A manual is being worked on with the aim of releasing it in the 2.0 stable release.

Succes en bij vragen kan je altijd hier terecht!
@vincent-mod dank je wel/thanks.Â
Het FOV wat ik bedoelde Is mijn vrije zicht vanuit mijn tuin van NO tot ZW. Orion is nu in zuid.Â
Ik hoop nog op wat heldere avonden om nog voldoende light frames te krijgen.
Wat is het maximum aantal ligth frames om de satelliet sporen weg te krijgen?
English:
The FOV what i mean is the free aight i have from my garden, from NE until SW.
what is the maximum of light frames to remove the satellite trails?Â
Er is niet echt een maximum, eerder een minimum. Het hangt ook af van de hoeveelheid aan sporen in totaal. Maar in principe heb je vanaf 30 frames vrij goede rejection.
@vincent-mod okay dank je wel. Dan is het alleen maar nog hopen dat er nog wat heldere avonden komen. Dank voor al je hulp
