There should be one or two or more "new sky chart" that could be applied to the Observatory that would allow when activated to speed up explorer's time for treasure or adventure search during XYZ amount of time.
Explorer Treasure search could be 1 sky chart.
Explorer Adventure search could be another sky chart.
Geologist deposit search speed up with another sky chart.
This would allow different type of players to use the Observatory even if they do not adventure or rarely they could use the geo explorer speed sky chart.
I know you had this type of event during summer where all explorer or geo where speedier could probably bring something new to the Observatory.
It is a large foot print building and the design is nice it should have more and offer different functionality!
thank you for looking into this suggestion
