Field Flattener with T-Adapter for f/5.5 to f/6.0 Skywatcher Refractors
ETA: JAN 2021 (it might also arrive in the November shipment...but there is no confirmation about that yet...)
Field Flattener for f/5.5 - 6.0 Skywatcher and Other Refractors with T-Ring Adaptor from OVL (Optical Vision Ltd, the official Skywatcher distributor in the UK and Western Europe).
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 that nicely matches some William Optics telescopes. Especially recommended for the Megrez 72 DDG Refractor.
Distance to sensor from the base of the T-thread is 55mm, so it can be used with a usual T-ring and dSLR, such as Canon or Nikon. This distance can usually be easily achieved by other T-rings and cameras as well.
