Takahashi Tube Holder for FS-78 / Sky 90

Product Overview

A Takahashi clamshell tube holder for the FS-78 and Sky 90. It does what the name implies — it holds the tube in a clamshell-style ring so the optical tube assembly can be mounted to a Takahashi mount.

Who It's For

This is a good match if you own an FS-78 or a Sky 90 and need Takahashi's own holder rather than a generic ring.

Key Features & Design

• Clamshell design: the holder opens to seat the tube and closes around it.
• Fits the FS-78 and Sky 90: the two tubes share this holder.
• Takahashi construction and finish: matches the tubes and mounts it works with.

Recommended Uses

Mounting an FS-78 or Sky 90 to a Takahashi equatorial mount for visual observing or wide-field imaging, or carrying either tube as a guide scope on a larger rig.

Compatibility and Accessory Notes

Listed by Takahashi for the FS-78 and Sky 90. Takahashi's holder range uses closely similar model codes across tube sizes, so if you are matching this to a different telescope, send us the model and we will confirm the bore against it before you order.

Good to Know Before You Order

Sized to these two tubes: the bore is machined for the FS-78 and Sky 90 and does not adjust to other Takahashi models.

Frequently Asked Questions

Is it difficult to set up?

No — the clamshell opens, the tube seats inside, and it closes around it; the base bolts to the mount.

Which telescopes does it fit?

The FS-78 and the Sky 90.

Can I use it to carry one of these tubes as a guide scope?

Yes — the holder is what fixes the tube to a plate or rings on the main rig.

Bottom Line

Takahashi's clamshell holder for the FS-78 and Sky 90 — the manufacturer's own mounting interface for those tubes.
