Chromatic Aberration?

Bueno! (That's Californian for "hello!")
I just got in my 85/1.8 and was playing around outside - took a photo of a drippy faucet - when I opened it up in PS I saw an ugly glow on the edges. I think this is "chromatic aberration" - am I right?

But then I read where this guy: http://tinyurl.com/ek3k2 said I didn't need to waste money on ED glass because:
"Extra-low Dispersion glass." Nikon started using this only in their super speed super teles in the late 1960s. These lenses say "ED" on and have a gold band around the barrel. All ED lenses say so.
Since only the most expensive lenses used or needed this glass it acquired a cachet. Therefore Nikon started using the moniker on cheaper lenses, and today it seems everything says ED on it. Short and normal lenses have no need of this glass; it's benefit is reducing secondary chromatic aberration, which is green/magenta color fringes that used to plague lenses of 300mm and up."
So if that statement is true, and my lens is only 85mm and what I'm seeing is chromatic aberration - what gives? Thanks pros for the tips.
