Pair of Vixen green tube rings, 115mm ID. 3-point screws (nylon tipped, locking collars). $60 shipped. (New price $75 + shipping)
Let me know if you have any other questions. Thanks,
I'm selling this OTA because my GP-DX mount with SkySensor was stolen a few weeks ago (grrr...). I considered replacing the mount, but eventually decided to sell the rest of my stuff instead. See my other ads for C9.25 OTA and various GP accessories; $5 discount per additional item ordered. Also, if you need random GP-DX fittings (plastic knobs, gears, plastic motor cover, manuals) let me know; if it's something I've got, I'll sell it to you for just shipping costs.
