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.
Hey, y'all. I'm pretty new to the realm of astro stacking and am still learning. I've been reading that having a dark frame library is a helpful tool, and I was just wondering how accurate the temperature has to be. If the temperature during light frame shooting is 60 degrees, would a set of darks that were taken at 55 or 65 degrees do the job, or does the temperature have to be exact? Thanks!
That depends very much on the dark current charasteristics of the sensor. What camera do you have?
You may want to look up the specs of the sensor and see if it is relevant. Having said that, DSLR cameras generally do not have active cooling for the sensors. This means that during a night of shooting, the temperature of the sensors in general increases due to all electronics at work. I don't know how to deal with that since I don't shoot with a DSLR camera.
A non-cooled sensor is a bit tricky. But what some do is to make a library depending on the outside temperature. Like a masterdark for every 5 oC difference. I didn't do much photography during summertime, but in wintertime my DSLR sensor easily reached about 30 oC anyway during intense use. Personally I ended up going for a masterdark for the winter and summer, together with a bad pixel map.
@vincent-mod Interesting. I will try that out.
