William Optics Flat6A III Reducer Flattener Adjustable 50.8 mm

The William Optics Flat6AIII is designed to smooth the image of your refractor and keep your photography sharp. It combines a flattener with a 0.8x reducer for an optimal field of view. So you get bright, sharp stars all the way to the edges of your sensor.

The flattener is adjustable, so you can match it perfectly to your telescope. This ensures that your camera on full-frame or APS-C sensors will correctly expose and focus over virtually the entire field of view. It is suitable for William Optics GT71, GT81, Z81 and Z103, but also works with other refractors between f/6 and f/7.5.

You easily mount it via your telescope's M63 connector. A 48 mm filter thread lets you add filters without losing image quality. All inner surfaces are black-coated to prevent reflections, and high-quality Ohara glass elements keep your image clear and rich in contrast.

The Flat6AIII makes astrophotography with your refractor easier and more precise. You get a larger sharp area, less distortion and more reliable results with long exposures.
