Quick Overview

  • 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

Product Details

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.
