  • Lunt Adapter T2 to 2" Eyepiece Tube

    The Lunt Adapter T2 to 2" Eyepiece Tube directly threads onto the T2 interface of a Lunt blocking filter, unlocking the use of wide-field 2" eyepieces for expansive views of the Sun.

    Upgrade Your Lunt System to Use 2" Eyepieces

    This adapter replaces the standard eyepiece holder on your Lunt blocking filter, allowing you to move beyond the limitations of the smaller barrel format. It threads on securely for a rigid connection that can easily support heavier, wide-field 2" eyepieces and accessories.

    It is compatible with most Lunt solar hardware, including H-alpha telescopes, Ca-K telescopes, and Ca-K modules. Note that this adapter is not designed for use with the LS35THa telescope.

    Brass Compression Ring for Secure, Mark-Free Clamping

    To protect your investment in 2" accessories, the adapter features a non-marring brass compression ring. Unlike standard thumbscrews that dig directly into the eyepiece barrel and cause scratches, this internal ring tightens evenly around the barrel.

    This design provides a secure, centered grip that holds your eyepieces firmly in place without leaving any marks, preserving their condition and resale value.

  • How do I install the Lunt T2 to 2" Adapter on my blocking filter?

    Installation is straightforward. Simply unthread and remove the original 1.25" eyepiece holder from your Lunt blocking filter. Then, carefully thread the Lunt T2 to 2" Adapter onto the exposed T2 threads until it is snug. No tools are required.

    Which Lunt solar telescopes are compatible with this 2" adapter?

    This adapter is compatible with most Lunt solar hardware that uses a blocking filter with a removable eyepiece holder. This includes:

    • Lunt H-alpha Solar Telescopes (except LS35THa)
    • Lunt Ca-K Solar Telescopes
    • Lunt Ca-K Modules
    • Lunt Blocking Filters (B600, B1200, B1800, B3400)

    It is specifically not compatible with the LS35THa telescope.

    Will using the Lunt 2" adapter with a wide-field eyepiece show me the full solar disk?

    Whether you can see the full solar disk depends on the focal length of your telescope and the eyepiece you choose, not just the adapter. However, using this adapter with a low-power, wide-field 2" eyepiece significantly increases your chances of framing the entire Sun, especially in shorter focal length Lunt telescopes like the LS50THa or LS60MT.

    What is the benefit of the brass compression ring on the Lunt T2 to 2" adapter?

    The brass compression ring provides a firm, even grip on your eyepiece barrel without scratching it. Standard thumbscrews press directly against the barrel, leaving marks and gouges over time. The compression ring design inside the Lunt adapter protects your 2" eyepieces and accessories from cosmetic damage.

    Can I use the Lunt T2 to 2" adapter for imaging with a 2" camera nosepiece?

    Yes. The adapter provides a standard 2" receptacle that is fully compatible with 2" camera nosepieces. This allows you to securely attach a dedicated astronomy camera for high-resolution solar imaging, taking advantage of the larger format.

    Does this Lunt adapter require any special tools to install?

    No, tools are not required. The adapter is designed to be threaded on and off by hand, making it easy to switch between 1.25" and 2" eyepiece configurations at any time.
