TS OPTICS M68 1x FLATTENER FOR RC
TS OPTICS M68 1x FLATTENER FOR RC is a special order item. Contact us for more info.
The TS Optics M68 1.0x flattener for Ritchey-Chretien telescopes is compatible with GSO and other RC telescopes with a focal ratio of f/8 and 2.5"+ focusers with a female M68 x 1 thread.
It offers excellent correction across full-frame and illuminates a 60mm image circle. The working distance between the flattener and the sensor is generous at 89.5mm from the M69 x 1 female thread, enough to fit accessories such as rotators, off-axis guiders and filter wheels. The flattener features high quality multi-coating to eliminate reflections, even around bright stars.
For simple connection to common imaging equipment, an optional M69 to M68 adapter is available here.
