Description
· The FRC-300 is a flat field Ritchey-Chretien produced by Takahashi.
· This flat field astrograph is designed to produce a flat 90 Ø image circle for medium format photography or CCD imagery.
· This image circle can be used with the largest available CCD cameras for many years to come. The f/7.8 focal ratio enables the imager to produce images of smaller objects with amazing sharpness and contrast.
· The pin-point stars 10 microns at the edge and 2348mm focal length, produce a field free of astigmatism or coma, which will allow the FRC to resolve star clusters and fine detail in galaxies and nebulae across the entire 90mm Ø circle.
· The temperature compensated secondary holder insures pinpoint stars during long exposures. The optional dedicated f/5.9 reducer produces a 36mm Ø flat circle for CCD imaging at this shorter focal length.
