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.

 

Individual calibrated lights look OK, but final integration odd.

Colleagues, I am trying to understand why my individual calibrated frames look OK, however, my final integration has a lot of blotchiness. Attached is an example of my workflow. The question is about the fourth image down in this example. Any thoughts on this? Thanks in advance!

Hi Matthew @mmw09er,

From what I can see, it seems to me that your flats are not properly taken, even the calibrated light shows that vignetting is not fully corrected I think. Are you using a DSLR? The integrated result seems to show the sensor chamber more or less and I think this also shows slightly in the calibrated light, please double check how the calibrated lights looks with an extreme strech and also oversaturating it with color. That will show the problem I think.
