2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
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 🙂
