Mike,
I suggest you post your query to the Yahoo group Amastro. They will want
you to be more specific, though. Faintest by total integrated magnitude or
surface brightness? Of course, those figures are often unknown for nebulae.
Clear skies, Sue

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
