Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.
May 27 2026 APP 2.0.0-beta45 has been released !
Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.
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.
[Solved] NegativeArraySizeException error on combine RGB tool
Hi I am trying to combine 3 already integrated and registered frames into the RGB combine tool and have received the following error when re-calculate is hit.
Further info - The 3 frames are from two different cameras with different frame sizes [OSC and Mono] so on the registration page checked use dynamic distortion correction and unchecked same camera/optics. On testing these frames integrate without any issues, I juts cannot RGB combine them.
Hi has anyone seen this error? I have recieved a second error same message - this time 2 master frames which have been star analysed and registered and then on saving the registered files one file saves successfully, the second generates the message below:
Can you upload the files that produce the error in Combine RGB to our file server? Upload instructions are at the top of any forum page. Please create a folder called uu_vee_combine_rgb and put your files in there. Then let me know when the upload is done and I will see if I can find out what's going on. Thanks!
I tried to do a couple of things to see if I could resolve the issue. To set context I have 2 master files which are the summary of previously integrated frames. One master file a gray file shot with AS1600MM pro the other RGB with the ASI294MC pro. Same optics / set up were used
Â
The original master file for the 1600MM was really "messy" due to multiple sessions and the camera being in different positions so I cropped this to use for this purpose.
I have uploaded these 2 files into the folder named above.

The last attempt to register these 2 files; the star reg performed ok; the first part of registration appeared to be OK without any errors, but on saving the files i had this message:
The files saved though [the resulting new reg file sizes were very large - up to 7GB] and the resulting images were very interesting to say the least! - I did not upload these due to the file sizes but here are two screenshots:
@wvreeven Hi thanks for your response. I'm a little confused here as this issue arises during the register process; save registered frames [Tab 4] which precedes Normalise [Tab 5]Â
My plan here is to take the registered frames to do further processing and try some combination outcomes rather than completing integration.

This simply means that the resulting image is too large for APP to be able to process. How much RAM do you have allocated to APP? You can see (and configure) this by clicking the CFG button to the upper left of the APP screen.

Sorry for my previous short answer. It was referring to the distorted images that were produced by APP. So my question remains: did you enable advanced mode in tab 5?

Thanks for uploading the files. I loaded the two lights in APP 2.0.0.-beta8 and normalized them. All I needed to do was uncheck "same camera and optics" in tab 4. When trying to save them as FITS files, I get an error. I'll check with Mabula to see what the cause is.
@wvreeven Hi Wouter re you question on RAM; system has 32GB and I have allocated 30GB to APP. I would hope this would not be the issue! Thanks for the update on your tests with the actual files.
