  • Baader Adapter - M36.4(M)/T-2(M)

    The Baader M36.4 to T-2 Adapter provides the essential mechanical link between Vixen's proprietary M36.4 focuser thread and the universal T-2 (M42x0.75) standard used by most astrophotography accessories. This component allows you to securely attach your T-threaded cameras, filter wheels, and off-axis guiders directly to a Vixen telescope, opening up a world of imaging possibilities. It is a fundamental part for integrating modern cameras with Vixen's well-regarded optics.

    Bridging Vixen Focusers to the Universal T-2 System

    Many Vixen telescopes, particularly older models and spotting scopes, feature a female M36.4x1.0 thread on their focusers. This Baader adapter converts that specific thread to a male T-2 thread, solving a common compatibility challenge for imagers. By making this connection, you can now build a rigid, threaded imaging train using components from the vast Baader T-2 System or any other manufacturer that adheres to the T-2 standard. This single piece replaces guesswork with a secure, reliable connection for your imaging equipment.

  • What is the primary use for the Baader M36.4 to T-2 Adapter?

    This adapter is designed to connect a telescope or focuser that has a female M36.4 thread (commonly found on Vixen equipment) to an accessory that has a female T-2 (M42x0.75) thread. Its primary role is to allow modern T-threaded cameras and accessories to be used on these specific Vixen telescopes.

    How do I know if my Vixen telescope needs this Baader adapter?

    You need this adapter if your Vixen telescope's focuser drawtube has internal (female) M36.4x1.0 threads where you would normally attach an eyepiece holder or camera adapter. Check your telescope's manual or measure the thread diameter on the focuser. If it is approximately 36.4mm, this adapter is likely the correct part to connect T-2 accessories.

    Can I attach my ZWO ASI camera to my Vixen R200SS focuser with this adapter?

    This depends on the specific focuser version on your Vixen R200SS. While many Vixen focusers use the M36.4 thread, larger models may use different standards like M60. You must first confirm that your focuser's output thread is indeed female M36.4. If it is, this adapter will provide the male T-2 thread needed to start building a connection to your ZWO camera.

    Does this Baader adapter add significant length to my optical train?

    As a low-profile adapter, it is designed to add minimal optical path length. However, since every millimeter matters for achieving focus, especially with reducers or correctors, you should account for its thickness when calculating your back focus. Unfortunately, without official specifications, the exact length cannot be stated.

    Is the Baader M36.4 / T-2 adapter compatible with non-Baader accessories?

    Yes, absolutely. The T-2 (M42x0.75) thread is an industry standard used by countless astronomy brands worldwide. This adapter will allow you to connect any accessory with a standard female T-2 thread to your Vixen-threaded focuser.

    What is the difference between the M36.4 thread and a T-2 thread?

    They are two different mechanical standards.

    • M36.4 Thread: A metric thread with a 36.4mm diameter and a 1.0mm thread pitch, primarily used by Vixen.
    • T-2 Thread: A metric thread with a 42mm diameter and a 0.75mm thread pitch. It is the most common standard for attaching cameras and imaging accessories in astronomy.
    The two are not compatible without an adapter like this one.
