Product Description
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. We produce 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 do vignette the light path. We have incorporated the well-tested system of our 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 our ultrawide S52-clamping system. We will soon offer a 2" nose-piece with S52-ring-clamp. This 2"-nose-piece does provide you with an unobstructed clear inner diameter of 46mm and eliminates vignetting with the Sony Alpha 7 cameras even with very fast optical systems. The Baader SONY-E-Mount/NEX bayonet T-Adapter already got introduced in our last newsletter.
All Baader Wide-T-rings have an S52 dovetail in addition to the inserted T-2 ring. This allows the T-ring to be modified to an M48 female thread using the S52 / M48 adapter #2958552, or to use the S52 barrel #2958551 without the T-2 reduction. With the S52 / M68 adapter #2458252, the Wide-T-Ring can be directly attached to an M68 male thread to securely fasten your camera to the widest possible aperture.
All Baader Wide T-rings can be directly adapted to an UFC (Universal Filter Changer) with the optional Baader UFC S52 dovetail camera-adapter (#2459119), in order to change different filter sizes directly in front of the camera sensor.
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.
