Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
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.
Hello all!
I am trying to improve my bright star quality from my EdgeHD telescopes. Often, even despite having decent seeing (1.5" FWHM with subs in the ~2.2 FWHM range), I end up with bright stars that have mottling and fine diffraction lines around them. When integrating, I often see green on the top and red on the bottom, almost like chromatic aberration. This looks bad enough before processing, but tools like deconvolution make it worse.
EdgeHD 14, no reducer, Baader CMOS filters, ASI6200MM-Pro. Also, I have flocking material in most of my image train (though not all), from the EdgeHD's flattener on out to the front face of the OAG, including the external Esatto focuser (my mirror is locked). I think my collimation is very good, but I'll check that the next time we have clear skies.
Any idea what might be causing this? Is it possible I am doing something wrong while stacking in APP, or missing some feature that might correct this in post-processing in APP or PI?
The image below is based on 300s RGB subs. I am saturating a tiny fraction of the pixels at f/10.98, but I plan to reduce either the exposure or the gain just to see if it decreases the mottling around the bright stars.
For those of you in the US, happy Thanksgiving!
Hi @mountainair,
Please accept my apologies for the late reply to this question.
I am not quite certain what the cause would be of your issue as shown in the zoomed in image of the bright stars. But my first thought is, did you make sure that the EdgeHD is well collimated? Maybe it isn't and this is causing the issue?
Did you try the align channels in 2)Calibrate to remove the problem with the color channels?
