Jan 04 2026: 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. Unfortunately, Mabula was struck by a severe flu virus in the past couple of weeks and thus could not work.  He is getting much better now and he has resumed work to release 2.0.0 as soon as possible. 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.

Nov 28 2025:  APP 2.0.0-beta39 has been released !

It is a major update with a new and much improved registration engine and much better Multi-Narrowband processing !

I photographed M45 with an APS-C OSC camera. This is what the stretched image looks like immediately after processing in APP. Is the blue lacking?
How can I make the blue more vivid?

You should perform under Tools -> calibrate star colors a color calibration.

 

Did you use a filter? Why are there halos around the bright stars?

Is the fact that the shooting location is Bortle8 the cause of the halo? I did not use any filters whatsoever.
