The Svbony SV545 45/203 F/4.5 is a compact Petzval refractor designed as a high-performance astrograph with a built-in flat field. Its advanced 5-element optical system arranged in 3 groups delivers a naturally flat image plane without the need for an additional field flattener, simplifying the imaging train and eliminating backfocus calculations. The optical design is optimized for modern wide-field astrophotography.
