I have two suggestions for new tools in Ekos.
First one a tool like the « brain » of Sharpcap to help to define the best exposure time under some sky quality.
Secondly a tool to evaluate and help the collimation quality based on the roundness of the stars.
It might work evaluating his roundness on the most brilliant stars (with thresholds to define). It might give graphically the zone where the collimation is the worst (grid or something else).
