When storing files locally, downloading takes about 15 seconds and only after that has completed does dithering begin, which takes another 30 seconds. It would be a great time savings if these two things could be done in parallel.
Note: This is not super high priority for me since I have now swapped to remote storage, but saving time between frames is a great way to increase integration time.
There is a feature in my camera tab in Ekos called Fast exposure that will do what you want. I have disabled it as it failed the last time due to a bug. No one has suggested this is fixed. It works really well until a Meridian Flip where it fails to start because it suggests it is still taking images.
Maybe someone can let me know if the issue is fixed?
