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.
Hi All,
I'm about to use my 12nm HA filter tonite.
Just going to do HA in this session.
Do I just treat the subs as normal but select the correct box and add all the supporting files.
Just want to get the HA data ready for the RGB when the moon is not out.
Many Thanks
Paul
@paul-grace Hi Paul,
Do I just treat the subs as normal but select the correct box and add all the supporting files.
What box do you mean?
If your software writes the filter name to the FITS header then APP will detect itself that you have used an Ha filter. Otherwise when the popup comes you need to select it manually. Is that what you meant?
Apart from that, the processing steps will be the same as for any other data.

wot a fool..ofcourse theres less light with the filter so any files used not taken with the filter will show the issue on my pic DOH...bloody obvious when you put your brain in gear
New files being taken now...so glad I bought the ASI 183Mc Pro
Hi All,
Back again 🙂
I've now created all the supprting files with the 12nm Ha filter in line.
When selecting the files to load do I tick Ha or rgb?
I'm guessing Ha as the filter is was used.
Many Thanks
Paul
If you are taking and processing only Ha data in this session, with an One Shot colour camera,
then you should be selecting Ha extract in the Tab0 Algorithm drop down, and all files , image and calibration should be loaded as Ha.
You should expect a monochrome file at the end, as you are creating a file from a single channel on the colour chip.
After imaging RGB data later on, you will load the Ha as Ha in the RGB Combine module, and the RGB as the three red, green and blue channels, and using the HaRGB algorithm in the combine module.
That is how i would process this.
Many Thanks Andy
I'll do it now with 5 of each files to save a bit of time 🙂
@paul-grace glad to help. Thats a great result! Well done!
i did exactly the same routine on the same object.
the Ha provides the detail and the RGB the colour.
Its a great combo for this type of object that is Ha rich.
