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.

 

Master Calibration Files Don't Have Correct FITS GAIN Value w/ ASI cameras

Hi,

I have noticed that the FITS GAIN value for all of my master calibration files is zero ("0") even though all of the subs have correct gain and offset values in their FITS headers.  This also affects the master calibration file filename (...ISO_gain_0.0...). 

I use ASI cameras (both color and monochrome) and I noticed the field name for the gain in their FITS files is GAINRAW, so perhaps APP is looking for a different FITS field?

Just curious as it would be helpful to have the correct gain in the filename.

Thanks!

Steve

I have the exact same issue.  I have an ASI294MC-Pro camera using TheSkyX and in the fits header the gain is listed as GAINRAW but yet APP doesn't seem to read this.  Along the same line, the debayer pattern is also listed in the fits header but APP doesn't pick that up either.  I have to always remember to go in and select "Force CFA".  This can't possibly be that hard of a fix to have it read these values can it?  I attached a Flat .fits file for anyone interested.
