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.
Good afternoon, I'm sorry if the question is stupid. But I received data from Eta Carina on HSO from Telescope Live (in confinement I got this alternative 😊 ). I've been watching tutorials on youtube, but so far only with OSC cameras. I wanted to try working with mono camera data, although I only have a Canon 600da. I have 600s (2 x 300 ") of each filter already pre-calibrated that is, without darks, flats and bias. I would like to try SHO and HOO processing. Is it possible to do it in the APP? Tips or help, thank you in advance.
It is yes, you basically want all data in mono. If you have RGB data you want to split that up in R, G, B channels first by working with the "split channels" option in tab 2. If everything is mono, you can clear the data in APP (or restart) and load in each set of data and assign it to the right filter. When done, you can integrate them all at once and have registered integrations for each channel. These integrations you can clean up with the tools in tab 9 (most used is the Light Pollution tool to get rid of gradients), those integrations can then be loaded into the RGBCombine tool, also in tab 9. Here you can select presets like what you're looking for and play around with the mixing of channels.
I'd suggest to experiment with this and when you have some trouble somewhere, we're here to assist!

ps. We don't consider any question stupid btw. 😉
@vincent-mod
Thank you very much for the reply, and I apologize for the delay in the reply. But I had a personal problem, and I didn't have a head for the rest, even doing post processing. This week I will follow the tips and try to do my best. Since I also want to do the post-processing of the Soul Nebula that I did with my setup (from my balcony in Bortle 8 in the city of Faro, Portugal) and the Canon 600d and my new filter (at least for me) Optolong filter L-eNhance.
Absolutely no need to apologize, hope you are well and I hope the steps work next time around. Just let us know if they don't. 🙂
