I would like to suggest a feature for the planner... I think it doesn't exist yet.
Instead of setting start time and a certain number of exposures I would like to have a finish time...why?
In exoplanet observing if I have two targets in one night , the number of exposures gives me an uncertainty of the end time for the first target to end, delays of various sorts can extend the session duration.
Setting the start exposure time and end time is nice.
If not possible can I do it with a script?
