Conclusions/Lessons learned
• Amateurs/schools/observatory contributions don´t
fill the map
• Idea interesting for many media
• The Little Dipper already Lost a wheel Median 4th Magnitude
• Wide coverage essential!
• Attractive for joint efforts with protection of endangered species etc.

The next steps
• Southern method proposed
• Method(s) to fill the gaps in unpopulated/-
popular areas
• support other national campaigns
