If I use this on my Sony A7iii and connect directly to a nexstar 8SE with a focal reducer, what would be the correct back focus?

Hi there - I'm a little confused - in the description at the top it says that from the front support surface to the image plane of the camera, this represents 55mm. However, this ring is only meant to add 8.3mm to the 18mm backfocus of e-mount cameras. That would give a total backfocus of 26.3mm...so my question is if I want to connect my e-mount camera to the back of a field flattener which requires 55mm backfocus, is this adapter enough, or do I need to add approx 28.7mm of spacers? Thank you and sorry for the long question.

I see a hex key in the picture. Does this mean the camera can be rotated then locked axially, once the imaging train is screwed together.

Description

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. 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 vignett the light path. We have encorporated 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.

Please check out the GIF-Ani which explains how to refit from T-2 to M48 (center) – as well as the gain in clear aperture (left/right).

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.
