D&G Optical refractor mount on tall metal pier. 1.5" shafts, improved/larger bearings than standard offering. 5" Byers drive. 7-8lb counter weight. Extra 8lb stainless counter weight not pictured. Very capable mount for a long focal length 5-6" refractor. I was using it with a 30lb 5" f/12. $1100 plus shipping. Mount is larger than it appears in the photo. Rings not included but longer saddle plate is.
