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.
The other night I did my first imaging session which required a Meridian Flip. I'm using an ASI294MC Pro cooled camera. I'm also imaging the Dark Shark nebula. I noticed after the Flip that all the images after the Meridian flip were 180 degrees flipped as well, pointing in opposite direction...
So I had about 80 images with the shark facing one way and about 40 that were pointed 180 degrees in the opposite direction...
My question, will APP see this and put these in the proper position before stacking them for me? Or do I have to manually rotate them all myself first, before running them thru APP...
I thought these dedicated cameras it didn't matter about a Flip and they would all be in the same position. Maybe I'm wrong, obviously I am...
I think when I rotated these that it messed up my image creating Gradients, a massive amount of the stuff too!!

@rockinrod APP detects this automatically so no need to rotate the images manually.
Â
Awesome! Now I know...
Another question related to the above issue. When I rotated those 40 or so images manually, I was told that the APP software loses it's ability on those frames to read the FIT data, thus causing this Gradient and Light Pollution problem in my images. Messing up my entire session...This does seem to be what is going on here. No matter how many subs I add trying to improve the image, it seems to get worse with more data!
Make sense? Â Thanks!

@rockinrod When you rotate the images manually, they will end up being rotated with respect to the flats and darks, unless you rotate those as well. The result is that APP cannot perform a proper calibration which leads to all kinds of issues. So, yes, what you say makes sense. In short: do not manually rotate any files. APP can handle them very well as they come out of the camera.
@wvreeven I am just trying for the first time to process pre flip and post flip images. Initially I am trying without calibration frames so just lights, but I don't get a stacked image at the end.
