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.
RedCat 51/ASI294MC Pro. After integration, seeing doughnut holes in medium-size/brightness stars:
I thought they are slightly defocused or there's a sensor tilt issue, but I don't see it in individual raw fits files:
Version 1.083.
Anything I can do with settings to prevent it?
@mseningmail-com In processing or post-processing there isn't anything you can do about this. How do you focus the RedCat? Do you use the Bahtinov-mask that comes with it?
@wvreeven no, I’m using ASIAIR and ZWO EAF. The seeing may have been less than ideal at the beginning of the session, but it automatically refocused when ambient temperature dropped 5 degrees. The process had worked for me very well in the past. Do you still think it’s a focus issue as opposed to APP clipping the stars somehow in calibration process? It didn’t clip larger stars…
Star reduction seems to have helped getting rid of doughnut shaped stars…
That may help yes, but the underlying issue is still present then. Good to see though that it does make it less obvious!
