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.
Hi all.
Ive been using APP for a few months now and have had some success, especially considering I only started with a telescope, a Nexstar 8se around 5 months ago. However, I took around 300 x 10 sec (ISAO 1600) exposures last night of the Cocoon Nebula. Ive calibrated all my different frames (Lights/darks/bias/flats) and analysed the stars. But, when I try to register them it is a flat fail for every single light frame. Ive trying altering some of the settings but to no avail.
I have noticed there is a bit of elongating of the stars (the ones that are far away generally) but some in the foreground are not to bad and seem pretty round.
Does anyone know how I can get to the end result in some way. Maybe I just need to tweek something I don't know. I am a novice by the way.
Any help will be greatly received.
regards

Sorry for missing your post! 10 seconds is very short and if you have any light pollution it could very well be that the signal is not good enough for proper processing after all calibrations are done. Also, sometimes calibration data can be bad, especially flats. Does it also fail when you take out flats and darks?
Hi Vincent. I agree its short but it works really well with all the others Ive taken and Im pretty pleased for a beginner.
Ive attached a couple of examples here (Andromeda, Bode, Dumbell Nebula and M106), albeit with a bit of noise due to my light polluted area.

I will try without the flats and darks but its strange that in this case it wont work, especially as these images include flats and darks. :-/
That is strange, but sometimes those happen as well. Usually they are explainable as it must be an issue in either the data or calibration data. Challenging to find out sometimes unfortunately, eliminating one by one is a good way to see what might be the cause.
