Improved internal memory controls (much more stable and faster on big datasets), fixed CPU image viewer, fixed Narrowband extraction demosaic algortihms.
Apr 29 2026 APP 2.0.0-beta42 has been released !
New improved Normalization engine, Fixed random crashes in integration, fixed RGB Combine & Calibrate Star Colors, fixed Narrowband extraction algorithms, new development platform with performance gains, bug fixes in the tools, etc...

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,
I love the star removal tool to help focus on only the target, but after working a couple of images through, there are very noticeable artifacts that look like pits in the image. Â These unfortunately stay with the image all through post-processing. Â I was able to mask/blend some of them with an inpaint/healer tool in Affinity Photo, but that creates its own visual issues, given the number of artifacts, especially in brighter regions of the data.
Is there a good way to deal with these, or perhaps a better practice when removing all the stars? Â The attached image is the initial stretch of the data once exported from APP as 32-bit float FIPS.
Â
Thanks, John

Well, I don't think there is in APP itself other than choosing to reduce stars instead of removal. It's not perfect yet, itis a very difficult thing depending on the data usually (e.g. if there is a very star dense field). We will of course work on improving it.
I've seen the same issue using .83 beta when increasing the threshold setting too much. I just downloaded the most recent version and it seems to work well.

It turns out that the star reduction does leave some artifacts behind, but only at the bottom of the image. This can be cropped out and only affects the bottom 20-30 pixels. Other than this small problem, the star reduction works very well, much better than Startools.
