RCOS 100mm Field Flattener...

For RCOS Telescopes equipped with 20RC Star Instruments Optics.

100mm lenses for the 20" Ritchey-Chretien Optics

Two element, air spaced 108mm lenses shown in the cell designed to bolt onto the 20RC Back Plate.

Designed exclusively for the RCOS 20RC with Star Instruments Optics, this Custom Field Flattener gives the 20RC a one degree flat field, significantly reduces off-axis astigmatism, while also reducing spot size of off-axis stars. The lens cell mounts onto the back plate or inside of the (non rotating portion) RCOS 2008 100mm PIR. There is no telecompression and will allow the optics to operate at native f/ratio.

Ideal for use with a 70mm diameter focal plane.
