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.
Hi,
I'm doing a complex stack, which I've decided is easier if I create several stacks (from the original CR2 subs), then stack the FITS results.
When I import most of the FITS files, I'm given the choice of treating them like an integration - at least I think that's what it's saying, the message confuses me. So, first question is, if I just want to use the FITS files like subs, do I click Yes, or No?
Also, I have just one stack that doesn't offer me that option, and just imports it as a Light. Why would this be?
Thanks, Brendan
Any takers?
If you want to use the integrations as new "lights" again to stack them, you select no and they'll be treated as lights.
Thank you.
Is there any reason however why I wasn't given that option with just one of my FITS files? It just imported straight as a light. I even restacked it and it did the same thing.
If that was an unmodified integration then I think it should ask you indeed. Was it a straight integration that wasn't changed?
Yes - just like all the others, but I wasn't given the option.
Interesting, are you using version 1.083? It should ask it I think, depending on the information it has per fits file. Anyway, shouldn't influence it in what you want to do.
I'm running 1.083 Beta3 so I'll download the latest version, see if that behaves differently. I also have 1.082 on another machine so I'll try it on that too. I thought it was odd - sort of implies that something in the FITS header isn't telling APP that it's an integration.
