Apr 9 2026 APP 2.0.0-beta40 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! 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. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...
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 am busy trying to process old sessions from my harddrive using the
latest version of APP 1.070.
As already posted some time ago, when doing Bayer Drizzle, in many
data sets things go wrong, showing areas ( triangleshapes ) with green
background etc.
Now today I tried to process a session from M106 of last year and no way
it wants to integrate correctly, either normal or with bayer drizzle, there seems
to be some faulty image that shifts a bit ( stacked with DSS or PixInsight all stacks
normal )
I just reinstalled version 1.068 and now all problems seem to have gone
( at least it stacks normal again )!!
Could it be a faulty instalation of V1.070 maybe and should I try again
to install V1.070 to see if the fault has gone away?
Attached an image I posted earlier ( M27 ) showing the effect when things go wrong.
Thanks for any hint(s)!

PD: Could this be a graphics card problem??
Alas, now just finished the whole workflow through APP and whenÂ
stretching the image other areas show up that shouldn't be there.
Evenso, the integration is correct, not as in V1.070
Any clues?? ( On the left Bayer Drizzled, on the right without drizzleÂ
shown in PixInsight with only Screentransfer )
Thanks, Mert
Can this error be caused by using droplet size 0.5 and scale 2.0 ( so image will be
2x as big on both axis )???
Any help on drizzling would be apreciated!!
I have read that data should be undersampled, in my case I am not sure,
setup 1 uses TS APO 102/700 with reducer, is this setup oversampled?
setup 2 uses a Maksutov 150/1900mm, same question. ( ok just checked, thisÂ
should be ok with good seeing 1" - 2" )
Both setups use ASI1600MCC as the imaging camera.
This is likely another user error from me!!
Regards,
Mert
Ok, just one more time since there is no feedback, maybe this
can be helpful for someone else.
I just tried again on the very same image set of M27 and used
Drizzle instead of Bayerdrizzle, now the result is fine so for as
far as I am concerned this can be considered as a user error or
simple a user without enough experience 🙂
