20 January 2021: Soon to be released APP 1.083-beta2 : improved comet registration, updated tools, new Star Reducer Tool and more...
16 November 2020 - Wouter van Reeven has officially joined the Astro Pixel Processor Team as a moderator on our forum, welcome Wouter 🙂 !
I have about 460 pictures of 360x180 panorama. Many overlaps at zenith. Actually I have several tries of the same panorama taken on different nights, so I have about 2000 pictures which can be used.
Is there a chance to stich them all together in APP? I'm getting warnings about downscaling and technical limits after trying to stich about 20-30 of the images.
I'm used to stich gigapixel panoramas in Autopano Giga but stiching dark skies has proven to be challenging. Transition between dark sky at zenith and light polution at horizon seems very difficult. Manipulation of such transitions gives easy visible bands between top/bottom of the images.
Is there a way in APP to solve this problem and prepare images somehow for stiching in Autopano?
Is it possible to batch save streched images with neutralized bg + saturation as tiff after registration?
Thanks for any tips!
You can try to do that, but it would require a hefty specced machine. When landscape is included, this is not something APP is made to do well yet. I would try to do it step-by-step, so smaller parts first and then try the bigger one. Before pressing the integrate button, you can always check where the panels end up after registration by choosing the "l-c-registered" preview mode on top of the preview window. This is faster than having to wait for the entire integration to finish and only then seeing it failed or succeeded. Do use the "calibrated projection" model in tab 4.
It is rather challenging though, just so you know, it may be that APP needs some more fine tuning to get that to work easier.
Looks like the 700 mpixel limit is a problem for me. My columns are 16 images high (from Canon EOS 550D) and I cannot even process one column at once. Am I doing something wrong?
How can I save images to .tiff after registration? I see there is a "save registered frames" button. It saves to .fits. Are those the calibrated images? How to convert from .fits to tiff? When I use convert on Linux I'm getting only bw images. What am I doing wrong?
Mmm, it might be too big of a project in the sense you do need loads of memory for tasks like that, and I haven't seen such a huge project with APP before either, so it might not be the best of experiences yet. What happens if you chop it up even more, half a column at a time? You likely also have to make it smaller in the end by quite a bit, just to be able to process it.
