Takahashi Large Accessory Mounting Plate (NJP & EM-500 Mounts)

Product Overview

This flat accessory mounting plate measures 300 x 220 x 10mm and attaches to an NJP or EM-500 equatorial mount saddle, giving you a flat surface for accessory rings, a second optical tube, or counterweight hardware.

Who It's For

This is a good match if you run an NJP or EM-500 mount and need a flat accessory surface beyond the standard saddle.

Key Features & Design

• 300 x 220 x 10mm plate stock: a large, flat mounting surface.
• Sized for the NJP and EM-500 saddle pattern.
• Flat surface: accepts accessory rings, dovetail bars, or a piggyback optical tube.

Recommended Uses

Piggybacking a second optical tube or guide scope, mounting accessory rings or counterweight hardware, and general accessory carrying on an NJP or EM-500.

Compatibility and Accessory Notes

Fits the NJP and EM-500 mount saddle pattern. Takahashi's own listing gives attaching an FS-152 as one example use — the plate's flat pattern works with any accessory or ring set that matches its hole spacing. If you are matching a specific optical tube or ring set to this plate, send us the setup and we will confirm the fit.

Good to Know Before You Order
