Takahashi CCA-250 98mm Spacer Ring 32.5mm

Product Overview

The 98mm Spacer Ring is a Takahashi M98 x 1.0 extension built for the CCA-250, most often paired with the TKA86580L super reducer. Takahashi publishes a 32.5 mm light path 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 run a CCA-250 with the TKA86580L super reducer and need to add 32.5 mm of spacing to reach your target back focus.

Key Features & Design

• M98 x 1.0 thread: matches the CCA-250 and Mewlon CRS body accessory family.
• 32.5 mm published light path: a fixed, known contribution to your back focus total.
• Connects through to the camera rotator: pairs with the TKP86003 adapter for rotator attachment.

Recommended Uses

Adding spacing in a CCA-250 imaging train that uses the TKA86580L super reducer, ahead of the camera rotator.

Compatibility and Accessory Notes

Built for the CCA-250 with the TKA86580L super reducer, and connects to the camera rotator via the TKP86003 adapter. The 32.5 mm figure is worth adding to your full back-focus total alongside the reducer and camera — 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 is a fixed-length spacer, not adjustable: if 32.5 mm does not land your train at the CCA-250's reducer back-focus target, a different-length ring is the fix rather than trimming this one. Send us your full CCA-250 imaging chain and we will work out the right combination with you.

Frequently Asked Questions

Is it difficult to set up?

No — it threads in between the reducer and rotator adapter with no adjustment involved.

What is it used for?

Adding a fixed 32.5 mm of spacing in a CCA-250 imaging train built around the TKA86580L super reducer.

Does it work with the CCA-250's visual accessories too?

It is a mechanical spacer with no optical elements, so it carries through equally in an imaging or visual chain, provided the M98 thread on both sides lines up.

Bottom Line

A 32.5 mm M98 spacer ring for the CCA-250, built to work with the TKA86580L super reducer and camera rotator.
