Coma Corrector PH for R200SS Telescope

The coma is an imaging defect in which the diffraction image of stars which are located on the edge of the field of vision appear to have a comet-like tail (coma). The stars do not appear as point-shaped, but instead are elongated and distorted. The coma corrector compensates for this error.

This very high-quality corrector is designed for the R200SS, but is also suitable for other Newtonian telescopes. The image illumination is 44mm diagonal, so it is suitable for full-frame cameras.
