Orion SteadyPix Digital/SLR camera camera mount. I no longer have the instructions but it still works as well as it ever did (which, to be honest, is not nearly as well as the Digi-T adapter I just got, which is why I'm selling this). New price is $34.95+shipping; this one is $23 shipped. Paypal preferred (no fee). Let me know if you have any questions.
