ZWO Atmospheric Dispersion Corrector
Purchased this on a whim as one was actually available - normally they are very hard to obtain (i.e. often sold-out and on back-order in most stores)
It is in pristine condition and I have tried it out precisely 3 times so it is in BNIB condition.
Brand new price is AUD$179+$15 Postage
