Takahashi AUX Ring for 645 Reducer

Product Overview

This auxiliary ring fits into Takahashi's 645-format reducer imaging train, on the telescope side of the 645 Reducer. It is a fitting piece rather than an optical part — the reducer itself carries the correction.

Who It's For

This is what you need if you are assembling a 645-format reducer imaging train and your telescope's system chart calls for this auxiliary ring.

Recommended Uses

• Medium-format reducer imaging trains built around Takahashi's 645 Reducer system.

Compatibility and Accessory Notes

If you are assembling a 645-format train and want to confirm this is the correct ring for your telescope, send us the model and we will check it against the system chart with you.

Frequently Asked Questions

Is it difficult to set up?

It's a single ring in the 645 Reducer system — straightforward once you know which position it fills. Send us your telescope and we will confirm it's the right one.

Does this include the 645 Reducer itself?

No — this is the auxiliary ring only. The reducer optics are a separate purchase.

Bottom Line

In short: a fitting ring for the telescope side of Takahashi's 645 Reducer train.
