Hmm #FreeDcam https://f-droid.org/en/packages/troop.com.freedcam/ has a focus stacking option. AEF-bracket.. Produces the series of photos, doesn't actually combine them. Kindah making a mess of photos in a folder to later untangle..
Strangely the exposure time goes to 1/10s and my "main app" goes to a 10s.. It has a sequence-of-photos looks like you can set it to hours.. So maybe i could post-process those photos together for astro stuff.. If i can get the spoons together..
