  • Starlight Instruments 2.0" Adapter for Tele Vue Refractor Telescopes

    This Starlight Instruments 2.0" Adapter is the essential mechanical link for upgrading your Tele Vue refractor to a high-precision Feather Touch focuser. It is specifically designed to fit non-"IS" Tele Vue models, including the TV-76, TV-85, TV-101, TV-102, and TV-127, replacing the stock focuser assembly with a robust, zero-shift focusing system ideal for astrophotography.

    Upgrade Your Tele Vue Refractor with a 2.0" Feather Touch Focuser

    Tele Vue refractors are known for their superb optics, and this adapter allows you to pair them with an equally impressive focusing mechanism. By installing a 2.0" Feather Touch focuser—either Crayford or rack-and-pinion models—you eliminate the minor image shift and flexure common with stock focusers, especially under the load of a heavy imaging camera and filter wheel.

    • Direct Compatibility: This adapter threads directly onto the rear cell of compatible Tele Vue optical tubes, providing a rigid and perfectly aligned foundation for your new focuser.
    • Imaging-Ready Foundation: A Feather Touch focuser provides the ultra-fine control and high load capacity needed for critical focusing in high-resolution planetary imaging or long-exposure deep-sky work.
    • Important Exclusion: This adapter is not compatible with any Tele Vue telescope that is part of the "IS" (Imaging System) series, such as the NP101is or TV-76is, as they use a different mechanical interface.

  • Which Starlight Instruments focusers work with this Tele Vue adapter?

    This adapter is designed to accept any Starlight Instruments 2.0" Feather Touch Focuser. This includes both the Crayford (FTF20xx series) and the heavier-duty Rack and Pinion (FTF20xx-RP series) models.

    Will this adapter fit my Tele Vue TV-85 refractor?

    Yes, this adapter is fully compatible with the Tele Vue TV-85, as well as the TV-76, TV-101, TV-102, and TV-127. It is not compatible with any "IS" designated models.

    Why won't this adapter work with my Tele Vue NP101is telescope?

    The Tele Vue "IS" or "Imaging System" telescopes, like the NP101is, use a larger, proprietary threaded connection for their specific imaging accessories and focusers. This adapter is designed for the standard thread size found on the non-IS versions of Tele Vue refractors.

    What is the benefit of this adapter for imaging Jupiter with my TV-102?

    Using this adapter to mount a Feather Touch focuser on your TV-102 provides the micro-fine focus control essential for high-magnification planetary imaging. The dual-speed 10:1 reduction knob allows you to achieve critical sharpness on Jupiter's cloud bands, something much harder to do with a standard single-speed focuser, especially during moments of steady seeing.

    Is installation of this Starlight Instruments adapter difficult?

    Installation is straightforward for most users. It typically involves unthreading the entire stock focuser assembly from the rear of the telescope tube and threading this adapter in its place. Once the adapter is secure, the 2.0" Feather Touch focuser can be installed onto it.

    Does the Starlight Instruments adapter allow the focuser to rotate?

    The adapter itself provides a fixed, threaded connection. However, most Starlight Instruments 2.0" Feather Touch focusers have a built-in 360-degree rotation mechanism, allowing you to orient your camera or eyepiece to the desired angle after it is installed on this adapter.
