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 stacked 29X180 sec subs with darks, flats and dark flats in APP.  The smaller stars in the stacked image are purple.  I used the exact same data in DSS and the stars look normal.  What is the problem?
Camera is the 2600MC.  I also needed to force debayer on the subs. I thought APP would recognize the data as color subs automatically?  The images below are with 15% stretch.
Thanks
that's interesting. i am having a similar problem with my unmodified dslr, canon 6d. Â
@stephanhamel22 Hi Stephan. There are several factors that can influence the star colors. Can you tell us more about the data you're using, particularly the flats? How did you take them? What was the light source? Was any filter involved? As for the other images, are the gain, offset and temperature for all the same?
Regarding the automatic recognition of color data: if the application you use to shoot the images includes the Bayer pattern in the FITS header of the file then APP can detect that. Some application do not include the Bayer pattern in the FITS header and in that case APP needs to be told how to debayer the images.
Hi, any solutions for this issue?
