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.
I am very happy with the new Multi-NB extraction method, it saves me a lot of time. Question I have is how should I approach drizzling of the Ha data. Should I still stick to Bayer drizzle, or is it different because this is greyscale data? And what about the droplet size in this specific case? Any advice or guidance is appreciated.
Hi Tom @tvanpeer,
Thank you very much for your message. Great to hear that the new Multi-NB method is working nicely for you 🙂 !

The data, allthough grey is still Color Filter Array = CFA data that needs to be demosaiced/debayerd, so yes, use Bayer Drizzle. Bayer Drizzle settings I recommend are :
- scale 1.0
- droplet 2.0
- drizzle kernel Gauss
If the result looks good, but you want to see if you can get it sharper, try lowering the droplet size to 1.5 for instance. By lowering the droplet size, you might increase sharpness in the result, but it can also become more noisy so you will need to find a balance that suits you most 😉
Let me know if this helps.

Thanks Mabula, that is certainly the starting point I was looking for. In my RGB set for the same target I could scale up to 2 with droplet size 1.5. I assume that if droplet size 2.0 works for Ha, I still need to go to scale 2 to get to the same resolution as my RGB set?
Hi Tom @tvanpeer,
yes it would 😉 Since it is Bayer Drizzle and you only work with the CFA pixels, to make your integration, you will need plenty of images though if you increase the scale. I would suggest to set the scale to 2, the same as your RGB and then vary the droplet size so you get the most preferred balance between noise and sharpness in your Ha data.

I hope 12 hours of Ha and 20 hours of RGB will be enough. The drizzled RGB image seems to look pretty good already.
