Group frames into panels for mosaics
I use APP a lot for Mosaics and it's pretty time consuming to stack each panel by itself first when doing 16 panels like i'm working on now, would it be possible to add a function to add all files and group each panel so APP would stack them all automatically without having to load each panel automatically?
Remember the time when we didn't have APP to create mosaics so easily? 🙂 Thanks for the suggestion, I'm not sure if this can be done automatically as APP doesn't know what belongs to 1 panel by itself. Maybe Mabula (@mabula-admin) has an idea on it.
Did you use advance integration and LNC? Those should help with getting the frames equal. With easy I mean the calibration and registration, this used to be a process of hours/days just by itself before APP.
I remember reading on the fora here that plate solving is on the feature list for a future update. This would be an excellent basis for the requested feature.
If I'm not mistaken, the normal registration of N images takes order (N-1) registration actions, but for mosaic registration it takes order N * (N-1) / 2 registration actions. With 34 panels (may latest mosaic) that's still feasible, but with 619 exposures (the total number in my latest mosaic) it would take forever. With plate solving, only order N blind plate solving actions would be needed to know where each exposure (or panel) is located on the sky.
Blind plate solving would help immensely to automatically group exposures into panels, or even allow proper identification of the location, orientation and scale of all the exposures in a huge all-exposures-in-one-go mosaic.
I'd love to help think about a means to set this up. Just let me know @vincent-mod or @mabula-admin if I could help in any way. I've been playing extensively in the past with my own homebrew stacking software (though never got as far as mosaics or distortion correction).
We do not need plate solving for the individual stacks ... the coordinates are already in the single subs ... Could be nice down the road to help with speed and accuracy though ...
For now it would be sufficient I could load all the subs of a 9 panel mosaic in one go and get 9 stacks out of it, instead of loading them 9 times individual and wait in between ...
