naked eye mag test (Blue Mountains)

I wanted to see what I could see, naked eye, at the CAO. So I sat on the observing pad for a good long time, beside Ian W, while he worked his Dobsonian. I stared at Ursa Minor and tried to pick off faint stars. I made notes and checked the magnitudes.
  • θ (theta): 5.3
  • star between η (eta) and ζ (zeta): 5.6
  • 19: 5.5
  • beyond stars 4 and 5: 5.9
So, a quick test suggests I can see down to magnitude 5.9.
