2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
Hi all,Â
I'm new to APP, and I shoot with a DSLR (Pentax K-1) and SBIG STF-8300CÂ Both one shot color cameras.
I'm looking for some tutorials on how to process the shots from these. I know that I have to convert my DSLR RAWS to FITS and I've got that handled. What happens after that is where I'm confused. the once video tutorial about DSLR is for an older version 1.054 and I've got the latest which appears to have been significantly revamped with the ability to create the master calibration frames.Â
Â
A written tutorial is also good if there's any of those for OSC processing.
Hi Craig, at the moment there is no written manual yet. Mabula is working on one which I expect in a few months.
Â
ps. not sure but the raw frames are not recognized by APP?
@vincent-mod
Thanks for the info. I was hoping for a video tutorial or web page that shows the newer version. But I'll muddle through and keep working at it.
And, no, as of now APP does not handle Pentax .PEF files (native RAW) or .DNG (another RAW option that I use). Both are coming in a future version from what I've read. But I hope .DNG comes quickly.
Can't tell for sure if DNG is supported in the next version, but it will be a rather big update so fingers crossed. The video's are indeed outdated by now, but should get you going nonetheless. If not, let me know here and I'll try to help you.
