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,Â
I'm having some problems in integrating the frames captured by my new QHY183C.
I've set the debayer pattern RGGB, that should be the right one for the camera, but the result is completely green while the single frames aren't. Are there any specific parameters I have to set in order to process the light frames properly ?
Could you try switching OpenGL off on top of the application? Just to see if it's gpu driver related.
If not, try without any calibration frames to check if there may be an issue in there.
I've tried both strategies but switching OpenGL has no effect.
Remove calibration provide a full white image.
I've set the pattern to RGGB (that should be the right one) and the algorithm to Adaptive Airy Disc, checking the box "force ...CFA".
Are there any other parameters I can try to play with?
Well that is odd, then I suspect a general data issue probably. Could you upload like 5-10 lights and your master calibration frames to our server? Top right of the forum are instructions on how to go there and please create a directory called "plicciar-colorIssue". Thanks!
Will do.
Thanks
Done,
I've uploaded the master dark, 5 lights and the result of the integration
Thank you for the support
Thanks, will have a look today (bit busy at the moment sorry)..
Very sorry, on it now!
So, loading in a light from your data, it immediately looked strange to me. APP is correctly applying the RGGB algorithm (no need to set it manually) and since there is more green in the data (R GG B) it looks a bit greenish. That will correct fine during processing.
However, the histogram and noise in the image look wrong;
As if you're clipping very much to the left of what the sensor can record. Looking at the metadata, I can see a gain of 1. That is very low, however could be because you need the highest dynamic range. The offset is set to 0 as well, this is not correct. Every sensor needs an offset and this is what is causing a further issue in your data when processing. Have a look at what gain setting and offset is considered good for your sensor and you'll improve your data immediately. 🙂
