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 Vincent,
Â
Thank you for you're kind words. It is challenging to image from my own backyard but in fall there will be a few starparty's I hope for some clear nights.

Verry good Image Jan,
Â
Â
Nice image! What's the exposure time/ISO @ F5,6?
Â
 Hi Max,
Â
Thanks 🙂 !
I did use an OSC camera at 0 gain. I've got also a Nikon d5100 (exact the same chip) and would use around iso 200.
The exposures where between 100 sec. (Moon at 70%) and 130 sec. With moon at 15%.
I did use an "duo narrowband" filter the idas NB1.
If I did use my idas lps D1 filter (with new moon) I would use 45 sec. Without over exposing the background.Â
