  • Baader Wide T-Ring for Sony Alpha & Minolta Maxxum - T-2 and S52

    The Baader Wide T-Ring for Sony Alpha and Minolta Maxxum cameras fundamentally redesigns the camera-to-telescope connection, using a native S52 dovetail and an included T-2 insert to eliminate the bottleneck that plagues standard T-rings. By providing a larger clear aperture, this system significantly improves the illumination of your camera's sensor, especially for full-frame models. For maximum light throughput, the T-ring adapts directly to larger M48 and M68 threads, ensuring your optical train is as wide as possible from the corrector to the sensor.

    The S52 Advantage: A Wider Light Path for Sony & Minolta Cameras

    Standard T-rings are limited by the 42mm diameter of the T-2 thread, which can cause vignetting or darkening at the corners of images taken with full-frame or large APS-C sensors. The Baader Wide T-Ring solves this by starting with a much larger S52 clear aperture. For backward compatibility with standard focusers and accessories, it includes a T-2 insert, but its full potential is realized when you remove the insert and connect directly to other S52 components.

    Unlocking the Baader System: M48, M68, and UFC Integration

    This T-ring is an entry point into Baader's modular ecosystem, designed to create a rigid, wide-aperture imaging train. By using optional adapters, you can configure the connection for nearly any high-end setup.

    • M48 Connection: Use the S52/M48 adapter (#2958552) to connect to the common M48x0.75 thread found on many field flatteners and coma correctors.
    • M68 Connection: For the largest professional systems, the S52/M68 adapter (#2458252) provides a robust connection to M68 threads, common on large focusers and correctors.
    • UFC Filter Changer: With the UFC S52 dovetail adapter (#2459119), you can mount Baader's Universal Filter Changer directly to the T-ring, allowing you to place filters as close as possible to the camera sensor.

  • What is the main advantage of the Baader Wide T-Ring over a standard T-ring for my Sony camera?

    The primary advantage is a larger clear aperture. Standard T-rings use the T-2 thread (42mm diameter), which can clip the light cone and cause vignetting on larger sensors. The Baader Wide T-Ring uses a larger S52 opening, improving edge-of-field illumination, especially for full-frame Sony Alpha cameras.

    How do I connect this Baader Wide T-Ring to my M48 corrector?

    You will need the optional Baader S52 / M48 adapter (#2958552). You first remove the pre-installed T-2 insert from the Wide T-Ring, then thread the S52/M48 adapter in its place. This gives you a female M48 thread for a secure, wide-aperture connection.

    Can I use filters with the Baader Wide T-Ring for Sony Alpha?

    Yes. This T-ring is designed to integrate seamlessly with the Baader Universal Filter Changer (UFC) system. By adding the Baader UFC S52 dovetail camera-adapter (#2459119), you can attach the UFC base directly to your T-ring, allowing you to use 2", 36mm, or 50mm filters very close to your camera sensor.

    Will this Baader T-ring work with my old Minolta Maxxum film camera?

    Yes, the Sony A-mount (Alpha mount) is mechanically identical to the Minolta A-mount (Maxxum mount). This T-ring will fit and function correctly on Minolta Maxxum film and digital SLR cameras.

    I have a full-frame Sony A7 camera and a corrector with a large M68 output. Is this the right T-ring?

    Yes, this is the ideal T-ring for that setup. To connect to the M68 thread, you will need the optional Baader S52 / M68 adapter (#2458252). This combination ensures your imaging train maintains the widest possible light path from your corrector all the way to your Sony's full-frame sensor, minimizing any risk of vignetting.

    How can this Baader T-Ring help reduce vignetting when imaging the Andromeda Galaxy (M31) with my fast refractor?

    Large targets like the Andromeda Galaxy (M31) fill the frame of modern sensors. A fast optical system produces a steep light cone that can be easily clipped by a standard T-2 ring, causing the corners of your image to be dark. By using the Baader Wide T-Ring's native S52 aperture, you ensure the entire light cone from your refractor's flattener reaches the sensor, resulting in more evenly illuminated images of large deep-sky objects.
