Is it possible to add manual filter wheel or filter drawer.option into EKOS? For an example when one filter finish capture, EKOS will prompt a dialog box and ask us to change filter and press "OK" to continue for another set of exposure.
You should probably post a topic in the Wishlist subforum, with how you think the feature should behave and when it should trigger. If you know how SGP is proceeding, you can describe that as a use case. I'm pretty sure the feature can be implemented if enough users support the idea.
