June 24 2026 APP 2.0.0-beta46 has been released !

Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.

May 27 2026 APP 2.0.0-beta45 has been released !

Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options

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.

A 4.6 hour stack (60 s subs) of M106 and accompanying faint fuzzies stacked, calibrated and processed entirely with APP. This will get many more hours of data next year, but with such a wide field (86 mm APO, 460 mm FL, 1.7"/pixel) I am always surprised how well a full (and only) APP process does. The star calibration is always excellent changing DPP parameters has improved the data compared to several completed photoshop layering and masking processes, since the faint level of the galaxy halo in this case did not get any additional noise. For other targets such as nebulae, some PS does help in wide field, but I will be curious about star reduction routines to come to APP.

This was created without any flats or flatdarks, and calibrated using darks and BPM if course. Next year with 4 times more data, APP will likely render it the way I like, smooth and natural with just the right amount of color saturation from a OSC camera with no filters, as was the case here. More integration will remove the need for me to attempt to use of high pass filter, deconvolution etc. to extra galaxy detail at this small target size scale. Anyway, using APP for 95% of my processing is a breath of fresh air 👍

Beautiful result (I love galaxies personally) and great to hear it's working out so well for you!

@vincent-mod

And with some very distant objects identified. LEDA 213956 is 10.05 billion ly away, quite amazing.

Indeed, I love to do that as well, many times I find that background searching even more interesting than my main object. 🙂
