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.
Hello Guys,
I am a DSLR user and sometimes i dont take dark frames but dither after couple of frames. Till now i have never faced any problem in DSS. I am not sure if APP allows stacking without Dark frames or not. Anyone can help me out?Ā
It allows for not using any calibration frame, but I'd highly recommend using darks as it will help your data. You don't have to create them every session, just one or twice a year depending a bit on outside temperatures. If you don't want to use them, you can also create a very noisy (long exposure) dark and create a Bad Pixel Map from that, a BPM can be used for a very long time with all your data.
@vincent-mod thanks for the reply. I usually try to take atleast 15 or 20 darks depending how long my subs are and how much temp fluctuations occurs throughout the night. But sometimes i feel lazy to take.🤣
One more question, everytime A BPM is created. How to use it? When to use it? Can it be used with any future stacks no matter what was the exposure time; ISO etc?
Can i make a BPM with a 10min dark and flats at particular ISO (lets say ISO 800), and use it later with any other stackings?
Ā
TIA
Yes a BPM can be used with whatever data you have. You can take your worst darks and create a BPM with that, save it somewhere and re-use it every time. I would once in a while have a good check to see how well it still performs on the pixel level, but you can usually use it for a year or more (depending on your sensor's characteristics over time). I do tend to still use darks together with it, but if you have no amp-glow you can use just a BPM.
@vincent-mod it means! By making a Good Bad Pixel map, i can use BPM, Master Bias And Flats, together with light, right?
