Binorum SuperStrong 2″/T2 Camera Adapter (External T2 Thread)
The Binorum SuperStrong 2″/T2 camera adapter provides a robust connection solution for attaching DSLR and mirrorless cameras to telescopes equipped with 2″ focusers. This precision photo adapter enables prime focus astrophotography with larger imaging sensors and provides compatibility with 2″ astronomical filters.
Versatile T2 Connection System
The adapter features external T2 threading (M42x0.75) that accepts standard camera-specific T-rings for Nikon, Canon, Sony, and other major camera manufacturers. Simply attach your camera's T-ring to the adapter's T2 threads, and you have a secure, rigid connection from your telescope to your imaging sensor.
The 2″ barrel inserts directly into standard 2″ telescope focusers and diagonals, making it compatible with a wide range of refractors, Schmidt-Cassegrains, Maksutov-Cassegrains, and Newtonian reflectors equipped with 2″ focuser systems. The larger 2″ aperture ensures your camera sensor receives unvignetted light coverage, particularly important for full-frame and larger APS-C sensors.
Integrated 2″ Filter Threading
The 2″ barrel section incorporates internal filter threading for 2″ filters, allowing you to use light pollution filters, narrowband imaging filters, or other 2″ threaded accessories without requiring separate filter holders or adapters. This integrated design maintains a compact optical train while providing essential filtering capabilities for astrophotography.
The ability to thread filters directly into the adapter proves particularly valuable for narrowband imaging, where you can install Ha, OIII, SII, or other emission line filters in the light path. Light pollution reduction filters like UHC or CLS filters can also be installed to improve image contrast when imaging from urban or suburban locations.
Precision Construction for Imaging
Manufactured from solid metal with precision machining, the SuperStrong adapter maintains critical optical alignment between your telescope and camera sensor. The robust construction prevents flexure that could compromise image sharpness during long exposures, while the precisely machined threads ensure smooth, secure connections that won't loosen during imaging sessions.
The adapter's design minimizes the optical path length, helping ensure adequate back-focus for most telescope and camera combinations. This compact design also reduces the moment arm on your focuser, preventing the heavy camera from causing focus shift or balance problems.
Ideal Applications
This adapter excels for prime focus deep-sky astrophotography, where you want to capture nebulae, galaxies, and star clusters directly through your telescope without an eyepiece. The 2″ aperture provides generous coverage for full-frame sensors (36mm x 24mm) and ample coverage for APS-C sensors, ensuring your images remain free from vignetting across the entire frame.
The integrated filter threads make this adapter particularly well-suited for narrowband imaging projects, where you'll frequently swap between Ha, OIII, and SII filters to capture multi-channel data for Hubble Palette or other false-color processing techniques.
Camera Compatibility
Compatible with all DSLR and mirrorless cameras when used with the appropriate camera-specific T-ring (sold separately). Works with Nikon F-mount, Canon EF/EF-S, Canon RF, Sony E-mount, Micro Four Thirds, Pentax K-mount, and other camera systems - simply select the correct T-ring for your camera brand and model.
Why Choose Binorum
Binorum SuperStrong adapters combine robust mechanical construction with precise optical tolerances, ensuring your astrophotography equipment performs reliably session after session. The integrated filter threading and compact design demonstrate thoughtful engineering that addresses real-world imaging needs, while the solid metal construction provides the durability and stability serious astrophotographers demand.
