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.

Hello Mabula,

I just started using APP and was able to do all steps including integration and saving.   However, when I transfer the final, saved image to Photoshop in either fits or tiff format I get an overwhelming artifact.  As I stretch the image, a checkboard or Herringbone pattern becomes evident that overwhelms the image.  I have tried some different actions including drizzle but it still remains.  I am guessing that it might have to do with the registration of my QHY163C images   ..  BGGR   one shot color.

Any guidance would be appreciated.

Thanks,

Leonard

Hi, I am getting the same colored checkered pattern after integrating my frames from an asi294 pro. I'm using the trial version of APP and have used pixinsight on this data with no issues. Is there something obvious that I am doing wrong.  Any help would be appreciated. 

Thx,

Alex

Thank you Vincent, I redid the calibration integration process and this time it turned out fine using the defaults.
