Takahashi RD‑EXT M‑300 Extension (TKA83205)

At 38 mm of solid extension, the TKA83205 lets you integrate the µ‑300CR reducer/adapter into your M72-wide imaging train. Its smooth bore guards against vignetting, while the rugged aluminum body resists flex under the weight of cameras or heavy filter wheels.

Finished with clear M72 threading and silkscreened identification, this extension sits near the rear of the train—setting the stage for everything that follows.

Cloudy Nights Community Insight:
M‑300 reducer users consistently point out that this extension ring is what finally made reaching infinity focus possible, especially when using additional filters or rotators.

Observing Tip:
Always start your M‑300 reducer train by adding this extension. It ensures your focuser draws from the mid-range and supports heavier payloads with ease.
