SVBONY SV194 T2 (M42) to Nikon F-Mount T-Ring Adapter

Product Overview

The SVBONY SV194 is a T-ring that connects a T2 (M42×0.75) thread to a Nikon F-mount camera body. It is the camera-side piece of a prime-focus astrophotography train: the telescope's T-adapter, flattener or extension threads into it, and it bayonets onto your Nikon SLR or DSLR in place of a lens. It is machined from aluminium in black and weighs 31 g.

Who It's For

This is a good match if you shoot with a Nikon F-mount SLR or DSLR and want to attach it to a telescope, spotting scope, microscope or lens adapter that ends in a T2 thread.

Key Features & Design

• T2 (M42×0.75) female thread on the telescope side.
• Nikon F-mount male bayonet on the camera side.
• Tight fit: SVBONY specifies a connection with no wobble or cross-threading.
• Aluminium construction with high strength and impact resistance.

Recommended Uses

• Prime-focus astrophotography with a Nikon DSLR on a refractor or reflector.
• Connecting T2 flatteners and reducers to a Nikon body.
• Digiscoping and microscope photography through T2-threaded adapters.

Compatibility and Accessory Notes

• Camera: Nikon F-mount SLR and DSLR bodies.
• Telescope side: T2 / M42×0.75. SVBONY also makes a wide M48×0.75 version of the SV194 for 2″ and M48 trains; each product contains one size.
• Spacing: SVBONY does not publish an optical length for the SV194. If you are building a train to a flattener's backfocus, send us your parts list and we will check the total with you.

Good to Know Before You Order

• Mechanical adapter only: there are no electronic contacts, so the camera runs in manual mode with no lens communication.
• T2 version: this listing is the M42×0.75 (T2) size.

Frequently Asked Questions

Is it difficult to set up?

No. Thread it onto your telescope's T2 adapter, then mount the camera body on it like a lens.

Will autofocus or aperture control work?

No. It is a mechanical connection; exposure is set manually on the camera.

Does it fit M48 adapters?

This one is T2 (M42). SVBONY makes a separate M48 version.

Bottom Line

In short: an aluminium T2 (M42×0.75) to Nikon F-mount T-ring that puts a Nikon SLR or DSLR at the end of a telescope or T2 imaging train.
