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.
I am a new user, started yesterday. I just stacked and did some processing in APP, then saved it to a TIFF file to the destination folder. When I opened it in Photoshop/LS 2021 the image looks nothing like it did in APP..It's like the processing I did did not hold, it's mostly black again...Wondering why the edits in APP did not take hold.
Any suggestions as to what causes this?
Thanks!

Did you make sure the "stretch" is checkmarked next to the save button?
@vincent-mod
I was still on the pre-process side (LH) of the screen...I haven't stretched it yet...Maybe that is why. Probably getting ahead of myself here. I was thinking the image you see as you do the mods on the left will be saved on my HD as I see them here.
Yep, that was it...So, I have to save the stretch from the RH side of the screen...Thanks!
RB
Ah, no indeed, the preview window is just that.. a preview. It allows you to work on tweaking the image in a linear space (so not stretched). This is always best for the data. Once you are satisfied, you click that save button with the stretch applied.
@vincent-mod
Yep, makes sense...This is just 2X180 subs, and the same cal frames just to play with for learning. Not bad for 6 minutes exp time. ASI294MC Pro cooled and a Meade 70mm APO Quad
Thanks again!
RB
APP has a very nice subtle stretching tool, lots of gadgets in here, as I will see as I keep learning this.
RB
Thanks. Nice result indeed! Yes, I'd advice to just play around as much as possible with APP (and if unclear you can just ask here) and make that image as nice in APP itself. That will make the data as good as possible for further processing.
@vincent-mod
Yeah, I'll dump in the 60 or so subs I have and see the difference then...
Still getting a few warnings too, about my flats mostly...Told me to do a Force Debayer to make it work. Where is this command located. Looked for this earlier and couldn't find it.
RB
Might be you have an issue with flats then maybe. If there is a real issue it's best not to use them, but just try and see. 🙂 Force CFA is in tab 0, but I would find that a bit strange as your regular files are from the same camera where it wasn't needed.
@vincent-mod That's where I messed up. Flats came from the Canon 800D, duh...DSS will use those APP will not...I need to tighten up...
Thanks I forgot. Been two years
I appreciate your quick response! I'm at it now doing the tutorials...
RB
Ah, no worries. Yes, DSS isn't very picky, but also not very good (not trying to burn other software at all btw, just from what I know 😉 ) in calibration. It's very basic and this means you won't get the best result out of more "complex" data situations.
But flats need to be from the same camera as that will dictate how the vignetting looks like, at what resolution, there might be dust on that specific sensor etc.
@vincent-mod
I sometimes use Nebulosity too...Does okay for some objects, not so for others...I like the way APP saves your changes at the bottom of the screen so you can refer back and forth looking at each change...
