50.8 mm sleeve for wide T mount

Conversion ring for mounting Takahashi wide T-rings on a 2.0" eyepiece holder
Description

This conversion ring allows you to adapt Takahashi wide T-rings, which own a M54 thread, on any 2.0" (50.8 mm) eyepiece holder.

The input mechanical interface has a 2.0" (50.8 mm) male barrel. The output mechanical interface has a M54 x 0.75 female thread (Takahashi Wide T-mount). An M48.5 x 0.75 female thread is available on the front of the ring for the possible screwing of a 2.0" filter. The backfocus generated by this ring is limited, only 11 mm, which allows to keep a reasonable length when mounting.

The reference surfaces, in and out, are shown on the schematic of the Characteristics section. We invite you to refer to the system-charts that are specific to your Takahashi Mewlon telescope to know what kind of assemblies is possible.
