Engineered for Deep-Sky Imaging
The SV555 is purpose-built for astrophotographers wanting maximum optical quality in a highly portable platform. Its flat-field Petzval structure removes the need for a separate field flattener, simplifying your imaging train while preserving sharp star shapes right to the corners of large sensors.
With support for full-frame cameras, cooled astronomy cameras, DSLR systems and EAF focusers, it integrates beautifully into advanced astrophotography setups while remaining compact enough for travel mounts and remote dark-sky sessions.
