  • William Optics Flat4 Draw Tube Adapter for FLT (Gold)

    This William Optics Flat4 Draw Tube Adapter provides the essential mechanical link for attaching a Flat4 series field flattener to specific William Optics FLT refractors. It is engineered for FLT models including the 98, 110, 132, and 152, specifically for telescopes produced between 2007 and 2016. The adapter ensures a secure, threaded connection directly to the focuser's draw tube, establishing the correct spacing and alignment for a flat imaging field.

    For FLT 98, 110, 132 & 152 Telescopes (2007-2016)

    This adapter is a required component for imagers using older-generation William Optics FLT quadruplet refractors who wish to use the compatible Flat4 flattener. Its threading and dimensions are precisely matched to the focusers on FLT models manufactured from 2007 to 2016, including the FLT98, FLT110, FLT132, and FLT152. The anodized gold finish is designed to cosmetically match the original trim and accents of these classic William Optics telescopes.

    • Specific Compatibility: This part is not universal. It is designed only for the specified FLT models and years; it will not work with other William Optics telescopes or focusers.
    • Imaging Requirement: Without this adapter, you cannot properly connect the Flat4 flattener to the telescope's draw tube, making it impossible to achieve a corrected field for astrophotography.
  • What is the purpose of the William Optics WO-AD4-A006-L00GD03 adapter?

    This adapter is a specialized mechanical part that allows you to securely thread a William Optics Flat4 field flattener onto the focuser draw tube of specific FLT telescopes (models 98, 110, 132, and 152) made between 2007 and 2016. It is required for astrophotography with that combination of equipment.

    Will this Flat4 adapter fit my 2010 William Optics FLT110?

    Yes. This adapter is specified for all William Optics FLT 98, 110, 132, and 152 models manufactured from 2007 through 2016, so your 2010 model is fully compatible.

    Is this adapter compatible with newer William Optics telescopes made after 2016?

    No. This adapter is designed specifically for the focuser thread pattern and dimensions of the 2007-2016 generation of FLT telescopes. Newer models use different focuser designs and require different adapters.

    How do I install this Flat4 adapter on my FLT132?

    Installation typically involves unthreading the standard 2" visual back or eyepiece holder from the end of your FLT132's focuser draw tube. This adapter then threads directly onto the exposed male threads of the draw tube, providing the correct connection for your Flat4 flattener.

    Does the gold color of this adapter match the original telescope?

    Yes, the gold anodized finish was intentionally chosen to match the distinctive gold trim and lens cell accents found on the William Optics FLT series telescopes from that manufacturing period.

    Can I use this adapter to connect a different brand of flattener to my FLT98?

    This is not recommended. The adapter is designed to provide the correct threading and spacing for the William Optics Flat4 flattener. Using it with another flattener will likely result in incorrect spacing, leading to poor off-axis star shapes and other imaging artifacts.
