Flats sub considere...

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 itĀ  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.

Hi,

I have a problem with the 1.075 version.

I don't why APP is considering all the flat subs as light. The software tries to analyse stars in the flat subs!

Regards.

Franck

The cause may be because of the name of my luminance filter called Light.

I check this problem.

regards.

My last post is the answer.

I change the name of the filter from 'Light' to 'Luminance' into my luminance subs, and into my flat sub.

Now it works.

I could change the name of the filter into the FITS header thanks to FITS4Win2 Header Data Utility.

You can find the website here :

Does your capture software call these files "light" also in the FITS header? This should be corrected with the capture-software, so tell at that stage that you want the flat frames to be called flats.

Dear Franck @franck_chile ,

I am fixing this, to prevent this bug from happening in the next release.

Is there any reason why you would name a filter: "light" instead of lum/l/luminance ? Is this common practice to name fitlers "light". I am just trying to understand why you would use such a naming convention šŸ˜‰

Anyway, I will make sure that APP will treat them properly next time.

Mabula

😀 I just named my Luminance filter like this at the beginning...

Now Luminance... it's not a common name.

Sorry for that.

Regards.
