TS 2" Field Flattener - Universal Field Flattening Lens

This revolutionary new field flattening system is the first one to our knowledge that offers a superior quality compared with conventional systems:

• Larger possible illuminated field through elimination of the "T2 keyhole". The flattener has 45mm clear aperture compared with 37mm for typical T2 adaptations.
• Excellent performance on a broad range of very different refractor telescopes from f/5 to f/8.
• Very large Back Focus distance of 109mm (exceptions: see belo). This allows you to attach extra accessories between the camera and the flattener, like off-axis guiders, filter quick changers, ...
• A multitude of different adaptations is possible. The flattener uses the standard 2" filter thread
• Visual use is also possible with the 2" filter thread adaptation - just screw the flattener into the 2" barrel of the star diagonal mirror - this will improve image sharpness towards the edge even for photographic use.
