I feel a little foolish for having to admit this but.....

I checked the mag limits in the 'Data Shown' options and found that
the limit for comets had been set to 6.7, obviously not realistic.
Don't know how that happened but since I'm the sole user of that
computer I must take the blame.

It would be nice, in this instance, if Guide were smarter than me to
let me know there was nothing within the limits set. Ah but then I
wouldn't learn near as much would I?
