I shoot with a Fujifilm X-T2 mirrorless when I don't use my dedicated astrocam. The trouble is the RAF files that it produces are so enormous that it can take hours to register and stack 100 lights. I thought if I convert the files to Adobe DNG it would speed it up and maybe it does but not so you'd notice. Does anyone know of a register and stacking app that might handle RAF files better (faster)? I've tried DSS, which is fair but much slower than it handles .FIT or .TIFF files out of my ZWO camera. I've also tried Astro Pixel Processor and it is super super slow, altho, in fairness, it does a lot more than DSS does which it should because it's not a free program. Any ideas would be appreciated. I haven't tried Sequator - I don't know if it will even handle RAF files.
