  • Adapter 1"a C-Mount to T-2i – incl. UV/IR Cut Filter

    The Baader C-Mount to T-2 Adapter provides the essential mechanical and optical link for integrating cameras using the 1-inch C-mount standard into the versatile T-2 accessory ecosystem. This adapter includes a pre-installed UV/IR Cut (Luminance) filter, delivering a complete solution for achieving sharp stars and accurate color balance right out of the box.

    Connecting C-Mount Cameras to the T-2 System

    This adapter bridges the gap between two common standards in astronomical imaging. It allows you to securely attach a C-mount camera—often found on planetary, guide, or industrial imaging systems—to any component with a male T-2 (M42x0.75) thread, such as off-axis guiders, filter wheels, or extension tubes from the Baader Astro T-2 System.

    Integrated UV/IR Cut Filter for Accurate Color

    Many sensitive astronomy cameras lack an integrated filter, leaving them susceptible to unfocused ultraviolet and infrared light that can cause star bloat and unnatural color casts. By mounting a UV/IR Cut filter directly within the adapter, Baader ensures your camera records only the visible spectrum, resulting in tighter stars and colors that are true to life, a critical step for one-shot-color imaging.

  • What is the main purpose of the Baader C-Mount to T-2i Adapter?

    Its primary function is to allow a camera with a female C-mount thread (a common standard for video, security, and some guide cameras) to be connected to the widely used T-2 (M42x0.75) thread system for astronomical accessories. The "i" in T-2i indicates an internal thread.

    Why is the included UV/IR Cut filter important for this C-Mount adapter?

    Most modern CMOS and CCD sensors are highly sensitive to infrared (IR) and ultraviolet (UV) light, which most telescopes cannot focus correctly. The integrated filter blocks these wavelengths, preventing bloated, out-of-focus stars and ensuring correct color balance, especially with refractor telescopes.

    Can I use this adapter to connect my C-mount guide camera to a Baader T-2 off-axis guider?

    Yes, this is an ideal application. The adapter allows you to rigidly mount your C-mount guide camera onto the T-2 threaded port of an off-axis guider, creating a secure and parfocal guiding setup within the Baader T-2 system.

    Is the filter in the Baader C-Mount to T-2i Adapter removable?

    The UV/IR Cut filter is factory-mounted and intended to be a permanent part of the adapter. It is not designed for easy removal, as its inclusion is a core feature for ensuring proper imaging results with unfiltered cameras.

    Will this adapter let me attach my C-mount camera to a standard 1.25" focuser?

    Not by itself. This adapter terminates in a female T-2 thread. To use it in a 1.25" focuser, you would need to add a separate T-2 to 1.25" nosepiece accessory, which would thread into the front of this adapter.

    What is the difference between C-Mount and T-2 threads?

    They are two different mechanical standards:

    • C-Mount: A 1-inch diameter thread with 32 threads per inch (TPI). It has a flange-to-sensor distance of 17.526 mm.
    • T-2 (or T-thread): An M42x0.75 metric thread (42mm diameter, 0.75mm pitch). It is a de facto standard for astronomical accessories.
