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.
Hello
When I want to make a mosaic with RGB images and monochrome images, there is an error message during NORMALIZATION process.
I use multichannel option and select RGB images, then Ha images (all images are preprocessed from 30 to 100 images).
I assembled first calibrated RGB instead of each R, G, B because of color difference in final mosaic.
When I only make mosaic with Ha, or only RGB, it works fine. When I want to process all, there is error
Please download the 4 images (2 Ha 2 RGB) here

This was working fine on previous version of APP as I already aligned 16 fields of this object, each RGB + S + H + O )
I am under MacBook Pro with Catalina OSX

Thank you for reporting, I'll download the files shortly to see if it happens here as well.
Sorry, just got around downloading the files. I tried to download the zip file your server is sending, but it doesn't want to open here. Could you try via wetransfer? My email is vincent@astropixelprocessor.com
OK I sent you wetranfer file
please download before 7 days
thanks

FYI it was not a ZIP but 4 files FITS
Ok, finally having some time to analyse. I always suggest to prepare a mosaic by first creating the seperate panels and normalizing + post processing them as far as possible in the linear stage. Then reload them to make a final mosaic. In this case, I made the Ha and RGB separately (absolutely amazing quality btw) and tried to combine those, but also ran into a Java error. I'll inform Mabula about it.
thank you Vincent
glad to see you can reproduce the error
Yes, you’re right, I also try to prepare each panel of mosaic before.Â
cheers
So I've had too many Christmas drinks I think. Normalizing H-alpha and RGB is not possible at the moment, it's because it then has to normalize 1 channel (Ha) against 3 (RGB) and how to do that needs to be tested well and might be in a future version. Also, the error is something APP should take care of more clearly and Mabula is going to look at that. In the mean time it should be possible if you seperate the RGB into 3 seperate channels. Also, just registering, skipping normalization and going straight for RGB combine will also work.
FYI this mosaic (in fact 16 fields each SII, Ha, OIII, R, G, B) has worked in previous version of APP : S, H, O + RGB with normalization too.
For sure, I could use 6 monochrome chanels (SHORGB) but RGB balance is more difficult. Or maybe I process each RGB in color to get neutral background, then I split chanels in R, G and B images, like you suggerred 😉Â
That must have been a slightly different workflow then as it has never worked exactly like this for normalization. But if you have all panels nicely processed, it should be possible also to skip normalisation. Apart from splitting the channels.
Mabula, did you get a look to this ?

Hello
Issue is still here in 1.076
This was working in 1.074...
best,
philippe
I'm going to have another look at it, will let you know asap.
Ok, so because I knew I would probably run into an error again, I tried a different approach (the right one, I was mistaken in my original reply). It may be that in your case normalization is going wrong (as mentioned above) as you can't normalize a 3-channel image with a 1-channel image, in that case you do need to split the channels. I loaded in all channels in multi-channel mode and set APP to create a mosaic and integrate per channel. In RGB combine I then added all data to their proper channel.
Here are the settings I used in screenshot;

Hi VincentÂ
Yes, this method is a good solution and maybe the only way to do the job.Â
That’s nice.
cheers
