  • 2" Nosepiece to M45a – for Hyperion® Zoom MK III

    This Baader Planetarium retrofit kit converts your 1.25" Hyperion® Zoom MK III eyepiece for use in any 2" focuser or diagonal. A secure M45a threaded connection joins the kit to the eyepiece body, creating a rigid, single-piece 2" barrel that improves stability and alignment.

    From 1.25" to 2": A Seamless Upgrade for the Hyperion Zoom

    The Hyperion Zoom is a versatile eyepiece, but using it in a 2" focuser often requires a separate 1.25" adapter that can introduce flexure. This two-piece kit replaces the standard 1.25" barrel entirely, threading directly onto the eyepiece's M45 threads to create a native 2" nosepiece. The result is a more stable connection, eliminating wobble and ensuring perfect optical alignment within your 2" diagonal or focuser.

    • Direct M45a Threading: Ensures a rigid, secure fit to the Hyperion Zoom MK III body, preventing any rotational play or sag.
    • Native 2" Format: Eliminates the need for a 1.25"-to-2" adapter, reducing the number of components in your optical train and the potential for misalignment.
    • Accepts 2" Filters: The nosepiece is threaded for standard M48 filters, allowing you to use your 2" nebula or planetary filters directly with the Hyperion Zoom.

  • Why should I use this 2" Nosepiece instead of a standard 1.25"-to-2" adapter with my Hyperion Zoom?

    This Baader 2" Nosepiece provides a more rigid, direct connection to the Hyperion Zoom MK III. It threads directly onto the eyepiece body, eliminating the potential for wobble, sag, or misalignment that can occur when stacking a standard 1.25" eyepiece inside a separate 2" adapter.

    Does this 2" Nosepiece for the Hyperion Zoom have threads for filters?

    Yes, the barrel is threaded to accept standard 2" (M48 x 0.75) astronomy filters. This allows you to attach your 2" filters directly to the eyepiece without needing any other adapters.

    How do I install the 2" Nosepiece on my Hyperion Zoom MK III?

    Installation is straightforward. You simply unscrew the original 1.25" barrel assembly from the main body of the Hyperion Zoom eyepiece, then thread this two-piece adapter kit securely in its place.

    Will this M45a adapter fit other Baader Hyperion eyepieces besides the Zoom MK III?

    No, this adapter is specifically designed for the M45a thread found on the Baader Hyperion ClickStop Zoom MK III eyepiece. It is not compatible with the fixed focal length Hyperion eyepieces.

    I use my Hyperion Zoom MK III in a large SCT with a 2" diagonal. Is this adapter a good choice?

    Absolutely. This is an ideal upgrade for that scenario. It provides a much more stable and secure connection in your 2" diagonal compared to using a 1.25" adapter, which is especially important for maintaining alignment with heavier eyepieces.

    Will this adapter help my Hyperion Zoom MK III reach focus in my fast Newtonian reflector?

    This adapter changes the barrel size from 1.25" to 2" but does not significantly alter the focal plane position. If your Hyperion Zoom already reaches focus with a standard 1.25" adapter, it should also reach focus with this 2" nosepiece. It does not add or reduce the eyepiece's back-focus requirement.
