(IAAC) Faintest naked-eye object?

[Dr. Michael Inglis]

Hi everyone,
I am doing some background research for an article I am writing to be  
published [eventually] in a nation-wide astronomy magazine [both in  
USA and UK].

My question to you all is:
What is the faintest object you have observed using ONLY the naked- 
eye? [maybe holding a deep-sky or H-alpha/Beta filter to the eye].

My sources tell me that perhaps Barnard's Loop may hold the record  
here, or perhaps M81/82?

if you have observed such an object, would you let me know, including  
conditions locations etc., etc..

All replies will be answered and sources quoted in the article.

Best wishes and clear skies,
Mike
