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 Mabula,
I hope you are doing well. I did search for similar issues but i did not find it yet in the Forum.Â
I am getting a very strange Artefact around the Stars when i combine Data sets from Different cameras. in this Case a Canon6D and a Canon70D
LNC was on 1st Degree 1 IterationÂ
Bayer x Trans Drizzle (Date was Dithered)Â
i am using the version 2.0.0 Beta 38
What could cause these Artefacts?
Thomas
I'm not sure I can be much help, but my initial reaction is that this looks like an optical issue rather than a processing issue.
I have a few questions that might help move this forward.
- What lens and what focal length was used for each camera ?
- Was the data from the two cameras combined before or after integration ?
- How many exposures and how many dithers for each camera ?
- What droplet size and scale were used in the drizzle ?

Hi i checked my frames and yes the shapes of the stars a quiet different. But I did not have issues the last time I combined them. I just added som more lights with the canon 70D but even if I cancel the new data the old one seems to have these Problems. but they did not occur last year.Â
The Cameras where Canon 6D 400mm and Canon 70D 200mm
i combine every thing all at once into one imageÂ
Exposure count is like 60-70 images (6D 60 images 120sek; 70D 70images 90sek)
I dithered manually every 5 sometime 10 images.Â
droplet size is 1
scale is 2 but I also checked 1 and 0.8 but they were the same.Â
I just found the setting diffraction protection (it seems like this is the answer so I will try this)Â
@connor231 the Answer was The setting with Diffraction Protection. Now my stars are Sharp
Thomas
Glad you sorted it out.
