Sky-Watcher Field flattener med T-adapter
Superb quality, non-focal reducing Field Flattener optimised for DSLR imaging on refractor telescopes with focal ratios of between f/5.5 to f6.0. Will also provide much improved results on refractors with focal lengths narrowly outside this optimised f/range. Integral T-Ring adaptor thread. High quality CNC machined body with gloss black anodised finish.
