It can correct the defect of field curvature of the user's shooting target; improve the imaging quality and shooting efficiency of the edge of the field of view;
It converts the 854mm focal length f/7 refractor into a 683.2mm f/5.6 system for faster and wider field astronomical and terrestrial photography;
In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, the flattens the normal field curvature inherent in refractors. This provides images that are sharply focused out to the corners of DSLR and CCD imaging chips;
SV209 0.8x reducer has a metric 63x1 thread; the telescope reducer flattener screws into the focuser to ensure a secure connection.
