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,

Just downloaded the latest version of APP to use the star removal tool. Has a stellar performance on a few of my images. On one image with a dual-band filter star reduction of the Ha data is going fine, but on the OIII data I get an error. I have attached a screen-dump of what is happening. Any idea?

Cheers, Auke

Hi Auke, @acolijn

Thank you very much for reporting this. Indeed, this error is thrown on some datasets... but we have already fixed it and very soon we will release 1.083-beta4 with the fix 😉

@mabula-admin Thanks for the quick reply. I found a quick and dirty work-around for the picture I wanted to process. I first cropped the image and then ran the star removal tool without a problem.

Excellent Auke @acolijn, Indeed, stacking artefacts on the borders were responsible for the issue, so your work around solves that exactly. The next version will be able to deal with the border artefacts as well.
