3 element Apochromatic Barlow. Fully multicoated optics, blackened edges etc. Unit is boxed and basically mint.
I have literally bought this from Ian two days ago. It is optically impeccable and works just fine for its intended purpose (Barlow). Unfortunately it does not fit my imaging train, so it is back to the market at the same price, $59 plus postage (pickup possible, I'm in Melbourne).
