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.
Looking to use an Astronomy Camera for time lapses. This requires batch processing of dark subtraction, and also keeping a colored debay matrix as well as kicking the files out as TIF rather than FITs. (tiffs then get stretched and bulk editing in Lightroom)
I can easily do batch conversions of FIT to TIF, but the images are black and white and will have some slight amp-glow. I hear PIX can do it, so I was curious if APP could do it as well.
I guess you can load in your data, go to the calibrate tab and calibrate them all, then further down you can save all calibrated frames. Then you can use these to convert to tif. Or is that not what you mean?
Will it save all calibrated frames as a color TIF? Then yea. Goals here are:
1. Dark, Flat and Bias subtracted from frame
2. Color frameÂ
3. Export as TIFÂ
I got the TIF portion handled easily by other programs, but the first 2 are the hurdle. Â
1. Yes, that's what the calibration does
2. It demosaics the frames as well, so when set correctly (usually automatic works, otherwise you might have to set "force CFA" on in tab 0) it saves it as color
3. You can batch save (tools menu) these files to convert them to tiff
OK, it worked. Was able to save the calibrated files as a TIF in the output as well. Now my next question is can any type of auto-stretch be attained like the 15% 20% etc that is in the DPP area? Â
Yes, but in the beta 2 versions.
I have 2.0.0-beta1
