Hi, i would support that. Astro-stacking seems to work already with mosaic data. 4 stacking groups of 2x2 mosaic data produce the attached result. (left screenshot, simple 2x2 mosaic from M31, i switched of background calibration, so that parts the mosaic become visible). Just the way Affinity Photo sets the outer frame of the stacked image is not changeable. If outer frame could be switched between "intersection" and "all data" that would do the job! The result with background calibration "ON" is seamles. Impressive enough now, so that i have the hope, its not that much work to enable mosaic stacking. Greetings and in good hope for future functions.

Hi, one addition that may help: when you import these Darks, they are shown as complete black pictures. Normal Affinity Photo stretches Darks to a grey picture with a gradient. In addition, if you just open the dark with Affinity Photo, you get an error, that the format is unsupported! So the Problem is definetly the format of the Darks and Flats that N.I.N.A produces...

Hi, i tried the astro stacking function, but when i start stacking, the process hangs forever. A first window appeares telling "Fehlerhafte Pixel erkennen" and nothing happens anymore. I use the latest Affinity Photo 1.10.1.1142 with Win 10 pro 21H1 This hang can be reproduced by adding 2 Lights and 2 darks *.fits produced by n.i.n.a. (latest beta). These files seem ok, when viewed for example by irfanview or stacked by DSS. Attached you find two Lights and two Darks, that reproduce the crash. I tried different Lights and Darks, but the result is allways the same, then i use *.Fits Darks. I hope you can help. I use a workaround to use Affinity for Astro, as i create Master Darks, Flats and Darkflats with DSS and use these single master darks/flats/... which are TIF files for stacking the lights with Affinity.
