About
Stellarvue's universal field flattener for full-frame and smaller sensors, made in-house to tight tolerances to avoid the spherical errors common in mass-produced flatteners. It threads straight into a Stellarvue 3-inch focuser on its M68×1 thread, with adapters supplied for 2.5-inch, Feather Touch and Moonlite focusers. Each unit is assembled to order with the extension tubes that suit the customer's telescope and the adapter that suits their camera thread, so the field is flattest at the camera's back spacing.
