A stock-standard GSO 2x Barlow, with ED glass, in 2-inch form factor with 1.25" adapter (both 2" and 1.25" openings have brass compression rings). Excellent optical and mechanical condition - only slight marks on the barrel/adapter from securing screws.
I don't have much use for it anymore and am taking a break from astronomy for a while.
Price: $50 posted Australia-wide. $45 local pickup.
(BTW, first to PM may not be the successful buyer, so give it a go if you're interested).
