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...
Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options
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 just tried using the "Super Pixel" algorithm. I was expecting the integration result file to have a resolution of about half that of my original images, but it is about the same. I got a 3011x3014 output from 3008x3008 exposures.
I thought a block of 4 pixels would be converted to 1 pixel.
Have I misunderstood what Super Pixel does?
Be adviced that superpixel throws away possible valuable data, it's usually used to get a kind of preview on the data. Here's a snippet of the tooltip for it, it averages pixels before any de mosaic is performed :
I think it's better to try lowering the integrate scale (integrate tab, all the way down), if your goal is to simply downscale.
@vincent-mod Thanks for that. Jim
I tried Super Pixel again and it now produces a half width and half height image as you would expect.
...and now Super Pixel produces original sized images rather than half sized ones again!
Perhaps some other parameter overrides it?
...and now it's working again.
@jim Intriguing! What changed in between attempts? Did you choose different parameters? Did you restart APP? What version of APP are you using?

I had tried changing composition options (full, reference and crop) but that didn't seem to make any difference. I also tried restarting APP but that didn't help. However the following day, after a PC shutdown and restart, it worked again.Â
I'm on 2.0.0-beta2
Interesting indeed. You opted not to simply downscale then in the integrate tab?

Is that better than "Super Pixel" in any way?
If you want to downscale the image, then yes that would be better. Super pixel can throw away some of the data, which might impact a better registration of the data.
