I have made the announcement before installing the page so that is why some
of you had "error 404" while trying to reach it. But now the problem is
solved as I have checked it.

Well, I believe this method to be more valuable concerning deep sky
observing because its reference is a nebulous object. With the limiting
magnitude estimate, the rating seems to "permitting" for I have had
experiences of quite similar LM (at about 6) and still different viewing
conditions on DS objects: haze seems to leave naked eye stars quite
unimpressed and are devastating for faint fuzzies.

Well, for me, it means "enough transparent to show natural skyglow".
So, clear skies to all, yann.
