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.
Hello!
Maybe this is a dumb question, but I was wondering if I could use data from an OSC sensor (like the ASI533MC-Pro) to make an SHO version by using the appropriate algorithms in the "0) RAW/FITS" tab to extract the corresponding emission lines and recombining them later on.
The use case I've been thinking about is OSC color data that has been captured from a dark site. I already own an L-extreme and Sii filters and use them on my light polluted backyard, but I'm wondering if I go to a dark site and collect full color data, could that be also useful to create SHO images?
Thanks in advance,
Lucas.
@ldipenti Hi Lucas,
No, that will not be possible. Both Ha and SII are red and cannot be separated from each other. You'll need to use the L-eXtreme filter for capturing Ha and OIII and the SII filter for capturing SII, even from a dark site.

@wvreeven Thanks Wouter, it was my hope that I could do some "narrowband imaging" from a dark site by using a technique like that, because otherwise to swamp the sensor's read noise I need very good tracking (that I don't have 🙂 )
Hi Lucas,
What you could try is to try to separate them like this...
1) Tab 0: Ha OIII extract Ha -> all the way till integrate: this will be your Ha for RGB Combine (Tab Tools)
2) Again in Tab 0: Ha OIII extract OIII -> you will need to normalize them again and then Integrate: this will be your OIII for RGB Combine
3) Again tab 0: Ha OIII Mono -> you will need to normalize them again and then Integrate: you can save as Luminance and pick it up a SII for RGB Combine

Here you can find the video I got it from:
Hope it it is useful,

@camarieu hi Carlos thanks for the suggestion. I was thinking that maybe the extraction algorithms were able to separate the two shades of red from Ha and Sii.Â
I will try this technique to see if it helps getting a nice image but I was looking to also get something scientifically accurate Â
Cheers,
Lucas
