June 24 2026 APP 2.0.0-beta46 has been released !
Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.
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.
When combining images from different scopes, the images need to be combined with some magnification adjustments to match different scope focal lenghts. I think this also requires the star shape and quality metrics to be adjusted accordingly.
Hi Astrogee,
You are totally right, APP is actually doing this and have been doing this for several years already.
After 4) Register, you will get adjusted star size/shape and quality metrics, because APP then knows the relative magnifications.Â
For instance, Star FWHM min, max (abd -- rel)
the abs is the absolute value found in pixels after star analysis.Â
the rel is the relative valye found in pixels after the correction found by registering the images.Â
Is this not working as expected?
This is what I get with 2.0.0-beta45, processing 15 subs, 3 subs per optical setup, so 5 different telescopes + cameras:
After star analysis:
After registration:
You see that even the star density appears because it is a measure of the star count per area sky. Notice the difference in the abs and rel values for star FWHM and shape. Also notice that the quality metric is changed after registration to reflect the relative focal lengths.
Please let me know if this makes sense or not,
Mabula
Ah I see! I didn't know what the relative measurement was for but its clear now 😀 Thanks!
