Volunteers needed for naked-eye sample (Full Moon)

Hi all,

Something you can do out there under a Full Moon. The imagination runs wild here!
I'm hoping to get a sample of naked-eye limiting magnitudes using the constellation Crux. In a few weeks, I'm going to re-sample near New Moon.
If you would like to participate. Tonight, or over the next few nights, could you simply note the magnitude of the faintest star you can see (naked-eye) from the attached map. I haven't shown all stars to magnitude 6. Somewhere between 7pm and midnight will be fine.

Then report two things back to this thread.
a) limiting magnitude b) whether it was an inner city, inner suburban, outer suburban or rural reading.

Thanks, Rob.
