Have a never used set of Parallax Rings, 19" that will fit a Meade Starfinder (see their website for details). They have never been used but have been sitting in my garage. They are tapped top and bottom (forget bolt and spacing but think 6" oc. 3/8" bolts). New these are $319 I will let go for $275 shipped UPS ground in US. Cashier's check, money order, ship personal check after it clears.
