Hi,
yes, this feature is really missing! Yesterday I tried out the plan mode for the first time (before I used only the autorun mode).
It is really unlogical that you can only enter the amount of lights as a number and not as an absolute clock time until you want to shoot images of an object. I have the same problem in my backyard: trees and neighbour houses restricting the visibility of objects. It is nearly impossible to manually calculate, how many light's to take to reach the destination time (what's with downloading time, time for meridian flip, time for autofocus, ...)
To get out the most exposure time in the night it is essential to do imaging until XY o'clock per object in a plan and not "100 lights".
@Tech@ZWO Please add this feature. It is really important.
Thanks a lot,
paulchen
