- Baader T-Ring to connect Sony E/NEX DSLR cameras on the Astro T-2 system
- With the ultra-short Backfocus of only 26.3mm (18mm camera, 8.3mm T-2 bayonet ring) many adaptations in combination with reducers / filter wheels are now possible for the first time. Furthermore, the illumination of the camera chips improved significantly, mainly because of the larger clear aperture.
- Camera-sided connection: Sony E / NEX bayonet
- Telescope-sided connection: S52, M48 and T-2 internal thread with 0.75mm pitch
The Sony Alpha 7 cameras – especially the 7S and 7SII – are very interesting for astronomical purposes because of their high sensitivity, short backfocus light weight and very compact body dimensions. Baader produces a very short T-adapter for Sony E-Mount/NEX bayonet, which adds only 8.3 mm onto the 18 mm backfocus of the camera housing. This enables an adaptation to all backfocus-critical systems like HyperStar or fast Newtonians. All other T-adapters with T-2-thread which are commercially available at the moment vignette the light path. Baader has incorporated the well-tested system of their protective EOS-T-Ring into the Sony-adapter: Besides the T2-thread, the design also includes an M48-thread – and even bigger – the outer part of Baader's ultrawide S52-clamping system.
Specifications:
- Manufacturer: Baader Planetarium
- Optical Tube Length: 8.3mm
- Camera Adaptable: Sony E/nex
- Inner Diameter / Clear Aperture: 41mm
- Outer Diameter: 60mm
- Inner Connection (Lens side): Thread, Dovetail Ring Clamp, S52, T-2 (m42 X 0,75), M48
- Outer Connection (Eyepiece/camera side): Bayonet
Baader part number: # TRING-S or 2408317
