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, I processed my first set of images and calibration frames with the trial version the other day with decent results, for a newbie! Today, I had lights 120x30, 60x60, 40x90 and 12x300, with lights,darks and flat darks matching each. I loaded them all at once and hit "integration", after two hours the image which was generated is totally black. Any thoughts?
I am attaching the TIFF and jpeg file of my first image that had no issues. Thanks!
Something went wrong with your upload of the black image, could you try again?
The attached image shows the result of the sessions of both days. On June 25, the results were as expected. The resulting output on June 26 had intermediate files for 30,60,90 and 300 sec, all of which were totally black when opened, as was the final result. Don't know if you can have any insight by examining the file outputs. Thanks.
So, tried it again, this time placing lights and calibration frames into different sessions (30,60,90,300 sec), with flats, dark flats assigned to all. Same result...totally black final image. What can I share to help diagnose the error? Would copying the console contents help?
Mmm, what settings did you use in APP, all on automatic? What is your exact workflow?
Vincent, thanks for your replies. I persisted and used my laptop this time which has a faster processor and 16 GB RAM vs 12 on my desktop. That, and it seemed I had loaded a couple of bad calibration frames during the first efforts. In any case, I did manage to generate a file which I could then process in PS. Thanks again.
@vincent-mod @mabula-admin Vincent (or Mabula)...back again with the same (or similar) problem. I have had intermittent success in using APP but have had several sessions where the final integration has no data and a black screen. I try to be careful adding lightd/flats/darks and dark flats and can't identify the problem. When looking at the file data I do see
SNR & noise NAN - 0 as shown in the attached image.
Also, quality score (infinity symbol) INTEGRATE
does this give you a clue?
Please let me know what additional info I can provide. Most settings are default (I did select multi-session, RGGB, Force Bayer and Ha-OIII color)
Thank you.
Ah yes, that points to a data problem for sure. Can you post some screenshots of your master bias, master dark and masterflat? And maybe also a sub? It almost seems like your noise floor is too low. What gain and offset do you use?
So that doesn’t seem like a big issue right away. Can you check the offset as well, it should be in the fits header in the window left of the image, I think a bit to the bottom of that list.
If all seems ok-ish, I think the best thing is for you to upload some files to our server for me to check. I’ll share the link later.
Hi Vincent, offset is 65.
@vincent-mod Hi Vincent...I processed new data of a new target and used new flat and dark flat subs with the previous MD created by APP for 90 and 300 sec. images and everything went well.
However, in an attempt to do some Hubble palette of today's images with OSC I ran into this error message when attempting to re calculate using the SHO Hubble 2 scheme.
Thoughts??
Sorry for the delay.. Mmm, so maybe I'd need the data for that to check.
You can upload some to our server (<- click that link) with username/password: appuser
Please create a directory called "john-quinn-hubble" and I'll have a look asap.
Thanks, Vincent
