Product Overview
The DSLR Wide Mount Camera Adapter is Takahashi's CA35 (TSA-102) ring, threading M72 x 1.0 male on the telescope side to M54 x 0.75 female on the camera side. Takahashi states a metal back distance of 28 mm for it — the amount it contributes to your optical train, not its physical length end to end.
Who It's For
This is a good match if you shoot with a TOA-130, TSA, or FC/FS series telescope and need the M54 interface a Wide Mount DSLR T-ring connects to.
Key Features & Design
- M72 x 1.0 male to M54 x 0.75 female: bridges the telescope's drawtube thread to Takahashi's Wide Mount camera system.
- 28 mm metal back distance: a fixed figure to build your back-focus total around.
- Black-finished metal ring: matches Takahashi's other camera-side adapters.
Recommended Uses
Mounting a DSLR through a Wide Mount T-ring on a TOA-130, TSA, or FC/FS series telescope for prime-focus imaging.
Compatibility and Accessory Notes
Fits TOA-130, TSA, and FC/FS series telescopes with an M72 x 1.0 male drawtube thread, and connects on the camera side to Takahashi's M54 x 0.75 Wide Mount DSLR T-ring system. The 28 mm figure is worth adding to your full back-focus total alongside your camera body and any flattener already in the chain — the Takahashi Back Focus Guide tabulates every Takahashi adapter's light path alongside each telescope's back focus target.
Good to Know Before You Order
It needs a matching Wide Mount T-ring: this adapter presents the M54 interface but does not include the camera-specific T-ring itself. Send us your camera brand and we will confirm the matching Wide Mount T-ring to pair with it.
Frequently Asked Questions
Is it difficult to set up?
No — it threads onto the drawtube on one side and accepts the Wide Mount T-ring on the other, with no adjustment.
What is it used for?
Connecting a DSLR, through a Wide Mount T-ring, to a TOA-130, TSA, or FC/FS series telescope for prime-focus imaging.
Does it include the camera T-ring?
No — it is the telescope-side coupling only. The Wide Mount T-ring for your specific camera brand is a separate part.
Bottom Line
An M72-to-M54 camera adapter ring with a 28 mm metal back distance, connecting TOA-130, TSA, and FC/FS telescopes to Takahashi's Wide Mount DSLR T-ring system.
