I am certain that the request has already been made to allow for re-focusing between targets in the Plan mode. If it has not been requested, I would also suggest the ability to set a time interval for automatic re-focusing after a set amount of time such as 30min, 60min, etc. The later would be useful when imaging the same target all night long.
Also, I don't think I have seen this request, but could you also provide the ability to not use the NB filter during the Plan mode for emission nebulae, planetary nebulae and supernova remnants. When imaging these objects the Seestar automatically inserts the NB filter which is fine when imaging at a light polluted site. But when in dark skies the NB filter is not only no longer necessary but prevents the good broad band light from being captured. The NB filter can be turned off when not using the Plan mode but it would be helpful to be able to set it to be off in the Plan mode as well.
