I am having an issue opening .fit files from my ASIair in Siril. Images captured with an ASI585MC camera, confirmed to be 32 bit 3 channel RGB files in other software, only open as 16 bit mono files in Siril. I’m on an M1 Mac mini, OS 14.5 Sonoma. Siril versions 1.2.1 => 1.2.3 all show the same behavior. Wondering if I have some setting wrong in Siril.
You need to debayer the images. You can do this at the conversion or calibration stage.
But if you are stuck by this kind of error, I strongly recommend reading the doc and/or some tutorials on our website first.
