Today's APOD is a wonderful view of the Eagle Nebula, imaged at Kitt Peak. The Pillars of Creation are clearly visible. I don't believe I've ever looked at M16. I am now wondering what it would look like in Norwood.

M16 lies 7000 light-years away in Serpens Cauda. Burham preferred the Star Queen Nebula as the nickname for this Messier; he thought the Eagle Nebula "a little too prosaic". The magnitude of 6.5 may initimate beginning telescope users, but Burham quotes a John Duncan as saying it is "no more difficult than the nebula in the Pleiades". I guess he was referring to Merope's Reflection Nebula.

Below are selected dates for which M16 reaches its highest altitude of forty-six degrees in the Baton Rouge sky...

Wednesday's APOD celebrates the twenty-fifth anniversary of Hubble (occuring this April). NASA, ESA and the Hubble Heritage Team have assembled a sharper view of the famous Pillars of Creation shot.

Astronomy suggests trying M16 either tonight or tomorrow night. I'm observing in a few minutes...but I don't know. I only have about an hour before the transparency degenerates (according to Danko) and I have a couple of other objects on my list. I might give M16 one shot.
