Takahashi Extension Tube L (TKP00106)

Need a touch more than 15 mm? The 30 mm Extension Tube L fulfills that need with the same quality and design philosophy. This slightly longer barrel is perfect for accommodating filter wheels, rotators, or larger cameras—offering enough extra room without compromising your mechanical or optical setup.

Elegant in its application and precise in its execution, this tube maintains collimation, focus, and balance—even under the rigors of heavy payloads.

Cloudy Nights Community Insight:
Astro-imagers say the L tube was “perfect when switching from color to mono chips plus filter wheel—it let everything stay in range without bending.” That kind of feature is easy to overlook, hard to live without.

Observing Tip:
Use when additional focus space is needed but you want to avoid deactivating dew heaters or losing focus range. It keeps focus consistent through temperature shifts and component swaps.
