  • Starlight Instruments 3.5" Adapter for William Optics FLT151, FLT152, FLT158 & TS152 Telescopes

    This Starlight Instruments 3.5" Adapter provides the mechanically rigid, zero-flexure connection required to mount a 3.5" Feather Touch focuser onto your William Optics FLT151, FLT152, FLT158, or TS152 telescope. Machined in-house by Starlight Instruments from high-quality aluminum, this adapter ensures that the precision of your focuser is perfectly translated to your optical tube, eliminating a common source of image shift and tilt in demanding astrophotography setups.

    A Precision-Machined Connection for 3.5" Feather Touch Focusers

    Upgrading to a 3.5" Feather Touch focuser is a significant investment in your imaging system's accuracy. This custom adapter is the critical link that guarantees the upgrade's success. It is not a generic part, but a component engineered by Starlight Instruments to match the exact mechanical interface of the specified William Optics and TS refractors.

    By creating a single, solid metal-to-metal connection, the adapter prevents the subtle flexure that can occur with multi-part or universal solutions, especially under the load of a heavy camera and filter wheel. This ensures your entire optical train remains perfectly orthogonal to the focal plane, preserving the exceptional field correction of your telescope.

  • Why do I need this specific Starlight Instruments adapter for my William Optics FLT158?

    This adapter is custom-machined to create a perfect, non-flexing mechanical bond between the FLT158's optical tube and a 3.5" Feather Touch focuser. Using a generic or mismatched adapter can introduce tilt and image shift, negating the precision of your high-end focuser and compromising image sharpness.

    Will this Starlight Instruments adapter fit any focuser other than a 3.5" Feather Touch?

    No, this adapter is specifically designed for the mounting pattern and dimensions of Starlight Instruments' 3.5" line of Feather Touch focusers. It will not fit other sizes or brands of focusers.

    What is the benefit of using this adapter over a generic solution for my FLT151?

    The primary benefit is mechanical rigidity. This adapter is a single, solid piece of machined aluminum designed for a specific telescope and focuser combination. This eliminates the potential for flexure and misalignment common in "universal" adapters, which is critical when supporting a heavy astrophotography camera train.

    How does this Starlight Instruments adapter ensure proper alignment for astrophotography with an FLT152?

    By being precision-machined for the FLT152, the adapter guarantees that the focuser is mounted perfectly square to the telescope's optical axis. This orthogonality is essential for achieving sharp stars across the entire imaging sensor, especially with the flat field of a high-quality refractor.

    Is this adapter made from the same quality materials as a Feather Touch focuser?

    Yes. It is machined by Starlight Instruments in their own shop from high-quality aluminum and held to the same high standards of precision and finish as their world-renowned focusers. This ensures a perfect match in both function and aesthetics.

    I have a TS152 refractor; is this the correct adapter to install a 3.5" Starlight Instruments focuser?

    Yes, this adapter is confirmed to be compatible with the TS152 telescope, providing the correct mechanical interface to securely mount a 3.5" Feather Touch focuser.
