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 downloaded the demo version of APP and really have fallen in love with it. I am using it to stack and do some color correction before porting to LightroomCC/PhotoshopCC/AI Denoise.
I got a good image of Thor's Helmet with lots of blue in the helmet, but when I am trying to get blue to show in The Statue of Liberty Nebula, I get a hint of it as purple at the bottom of the nebula but in the Hubble and other NASA pics, including from land based scopes, they have some bright blue in a couple regions. I worked on this for about 4 hours and it is the best I can currently do. I used the Slooh 17" planewave in Chile to capture 110 subs over the last year.
   I loaded 42 lums (50 sec ea) and 24 ea R, G, B all 25 sec ea. Should I be using less R&G or how do I determine what ratio to use if any to get the blue to show? Is it just hit and miss or trying different numbers of the filter subs?

@jeffpadell Hi Jeffrey,how did you exactly combine the LRGB files? Did you do a per-channel integration or all at once? If per-schannel, how did you combine the integration results? Does the nebula show up in the blue channel? What happens if you only combine RGB but not L?
I used step 1 to pull in each set of subs for each filter. then hit 6 to integrate them and got the Session for each master. I combined them in step 9 the combine RGB and put in my L, R, G, B, got some color, more when I hit saturate. The nebula shows in each channel although not that much for the blue. I didn't try it with just the RGB will do that. Here are
the Blue and the Red channels

Here is the image with just RGB and all the defaults didn't monkey with the colors when combining just accepted the defaults, and no HSL, adjusted the stretch a bit but that was it
Â
I pulled the file back into APP and played with the HSL got more of the orange color but still no blue.
Â
I should stick to B&WÂ ROFL
Â
Well it has to be the object as I get plenty of blue in NGC1977 the Running Man nebula

@jeffpadell The Statue of Liberty Nebula indeed does contain blue emission but to me it looks like it is OIII emission which doesn't come out very well with B and G filters. You'll need to take Ha for red and OIII for green and blue to be able to see the blue color in this nebula. The fact that some blue is present in your pictures can be seen by the fact that the center of the nebula is white and not red.
