undetectable?

[theskyhound]

As it turns out, setting the time slider doesn't fix the problem with it picking the evening over the morning in the Nightly Planner. I am working on a fix, among a few others, and if things go well, an update may be only a few days away.

A better fix for this problem is to use the Ephemeris:

Select 2020 F3 as the target object
Choose the Nightly Observing Ephemeris
Select today's date
Set it to display at least a month

Each line displays the best time to view the comet on that date. Right-click to open a chart.
