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 it  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.

I love APP. Superb tool and easy to use - but the most painful thing for a narrow band project is to have to select each image set for say HaRGB and assign to each channel - same for the flats and dark flats ... yawn. The rendoring of the image is faster!

My capturing software (SGPro) allows me to set folders and file names for saving of fits in an organised structure - hell even the info is held in the FITS header

 

What if you could define a template foldure structure eg.

- Object Name

-- Date

--- Scope

---- Light

----- Red

----- Blue

----- Green

----- HA

---- Flats

---- Light

----- Red

----- Blue

----- Green

----- HA

----DarkFlats

---- Light

----- Red

----- Blue

----- Green

----- HA

Then template the file name to include a filter identifier - or read the fits header. Maybe even a session ident / id

Given the above info I add ONE folder to APP and it does the selection for me !!

Pretty Please 🙂

Oh I just found the select channel based on header - works for Flats but not on Dark flats - it just sets MONO as the channel

Hi Robert @robbrad,

Actually if your capture software assigns filters in the fits header, which SGPro certainly does (use it myself 😉 ) then APP will automatically recognize the filters with the fits header tag option when you are asked to select the filter.

I can load all my lights of diffferent filters all at once 😉 . If it does not work on your  dark flats, it means the capture software was not told to use a certain filter, because it definitely will work if it did.

I will think about such a folder structure going forward 😉 The next release will make it possible to load/save your settings and whole projects and your suggestion fits perfectly into that of course.

Thanks @mabula-admin for coming back to me - the folder structure was me trying to organise the way to apply the fits to filters - I actually prefer what you have suggeted - would be good if you could add one parent folder and it worked accross all sub folders recursivley

The issue with DarkFlats is when I choose fits header it assigns it not to SII but to mono

Ok my mistake....!!

When you set as a DARK frame from SGPro - it does not set the filter tag.... That is why

I will try to set as BIAS - im trying to split my flats from dark flats in SGPro

I have asked Mabula about this. Perhaps this happens because the filter is stored as 'SII   ' (i.e. with trailing spaces). As soon as I have a reply from Mabula I will let you know.

If the filter tag is there APP will recognize it if you select use filter header tag. Possible spaces in the filter name are dealt with properly as well. You can use filtername "SII 3nm" as well without issues.

If the capture software does not provide the tag and you have selected use filter header tag, indeed, they will show up as having filter mono or rgb.

Okay, great @robbrad 😉 I have noted a possible folder structure as an option to load everything correctly at once though 😉 I will see if I can implement it in the next version.

Yes, for bias,darks and darkflats as well. It does not make sense to have filter tags since no light is coming in...

That is why we have the option to load them for all channels 😉 APP will matcht the correct masters with the correct lights based on iso/gain, exposure, sensor dimensions.
