Starfield Optics Starfield 1.0x Field Flattener: Optimize Your Astrophotography Setup

Field Flattening Function: The Starfield 1.0x Field Flattener effectively eliminates field curvature in fast refractors, ensuring a flat image field for the camera sensor.
DSLR Compatibility: Perfectly suited for DSLR imagers, it works exceptionally with refractors between f/5.5 to f/6.5 to flatten the field across the entire sensor.
Versatile Sensor Support: Also suitable for smaller sensors like 4/3rds or 1" sizes, with refractors up to f/7.5, without affecting the focal length.
Back Focus Requirement: Requires a standard 55mm of back focus, streamlining setup with no need for additional extension rings.
Clear Aperture Advantage: Provides a 38mm clear aperture, ideal for APS-C and smaller sensors, eliminating vignetting. Expands to 42mm with the optional 48mm adapter.
Flat Field Benefit: Maintains your telescope’s focal length while providing a flat field, enhancing imaging quality.
Build and Design: Features multi-coated optics in a high polish, hard-anodized aluminum body for reduced weight and durability.
Aesthetic Appeal: The all-metal construction adds a sophisticated touch to your telescope equipment.
Standard T-Ring Connection: Requires a standard T-Ring for attachment, with M42 T thread for camera connection.
Additional Filter Thread: Includes a 48mm filter thread to add a light pollution filter, enhancing image quality.
