I have a 3 month old 15" Obsession with Argo Navis DSC's.
Scope has the OMI- Torus mirror serial# 15-100-081103, you check their site for the mirrors specs, scope includes light shroud, Telrad and a weight set, and wheel barrow handles.
Also included in the price is a set of eyep's, 22mm Nag, 3,8,14mm Radians, 2" 2X Powermate, 2" Paracorr, Tectron tools and a 2" Laser collimater, and to top it off a $250 super custom built wood eyep case. The cost of the scope alone was $5300 shipped, i will sell for $5000 with the eyep set, for pick up buyers only. I'm not in a hurry to sell, so if anyone is coming to the Tampa FL area your more than welcome to come take a look.
Or Buy the scope without the eyep set for $3800,.
