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.
Please see the attached image. This was my final result after integration. I was using a Radian Ultra Triad filter with my ASI2600 MC.
Any thoughts on what went wrong or is this expected.
@msamazing That looks like light produced by the Moon to me. Did you take these images when the Moon was above the horizon? Note that the Moon is a strong OIII emitter.
If no Moon was visible then, yes, it may be light pollution.
The moon was not above the horizon but shouldn’t that filter cut out light pollution? I am using this filter:

@msamazing No, as I wrote the Moon is a strong OIII emitter (actually reflector) and you should avoid shooting OIII under moon light.
Having said that, the left and lower lower left of your image seem to have an excess of OIII when compared to other OIII images of this nebula on internet. That seems to indicate it is light pollution.
BUT it could be due to flats or other calibration files as well. Have you checked those and verified that they were taken correctly?
