Takahashi FSQ-130ED 0.7x 645 Reducer

Product Overview

The 645 Reducer 0.7x is Takahashi's focal reducer for the FSQ-130ED, cutting the telescope's focal length by 0.7x to increase imaging speed for large-format sensors. It produces a Φ70mm image circle, the widest of any 645-series reducer in the Takahashi line, sized for large medium-format backs.

Who It's For

This reducer suits FSQ-130ED owners running large-format or medium-format cameras who want a faster system for wide, deep-sky fields without cropping the sensor's full coverage.

Key Features & Design

• 0.7x reduction: increases the FSQ-130ED's imaging speed for large-format sensors.
• Φ70mm image circle: the widest corrected circle in Takahashi's 645 reducer lineup, suited to large medium-format chips.

Recommended Uses

Wide-field deep-sky imaging on the FSQ-130ED with large-format or medium-format cameras; nebula and galaxy field imaging where the wide Φ70mm circle is put to full use.

Compatibility and Accessory Notes

This reducer is specific to the FSQ-130ED and is a different part from the 645RD QE 0.72x (FSQ-106EDX4) and the 645 Reducer-CA 0.72x (CCA-250) — the three share a naming pattern but are not interchangeable between telescopes.

Frequently Asked Questions

Is it difficult to set up?

It installs into the FSQ-130ED's imaging train as a dedicated reducer.

What is it best used for?

Wide-field deep-sky astrophotography on the FSQ-130ED with large-format sensors.

Does it work for visual observing?

No — it's built to deliver a flat photographic image circle rather than a visual eyepiece path.

What else do I need with it?

Your camera's own adapter to complete the connection — send us your setup and we'll confirm the spacing with you.

Bottom Line

A 0.7x reducer for the FSQ-130ED delivering a wide Φ70mm image circle for large-format astrophotography.
