Helix Hercules 10" alt.-az. fork mount, used but not abused. I bought this here on AM last year in anticipation using them with a pair of 100mm RA binocs but have since decided to stick with my Apogee 88s. The mount includes a 3"x8.75" universal mounting plate and an improvised mount handle.
From Helix: "The new Hercules fork mount from Helix Mfg. is solidly constructed of 3/8" aluminum and beautifully anodized in titanium grey. Teflon bearing surfaces ensure smooth movement in both axises. The base is tapped with 3/8" (Bogen) and 5/8" (surveyor) holes so it can be used with a variety of tripods. Fork cradle depth adjustable to obtain perfect balance."
This mount accepts encoders/DCSs (NOT included, I don't have any).
Price of $235 includes CONUS (only) shipping.
Thanks for looking, Rick
