Binorum SuperStrong T2 30mm Extension Tube
Getting the backfocus right can make the difference between a sharp image and a frustrating night at the telescope. This T2 (M42x0.75) extension tube adds exactly 30 mm of optical path - no improvisation, no compromises. Both ends carry a T2 thread, so it connects firmly and cleanly between your telescope and any compatible accessory.
What it is for
Use this extension tube whenever the standard distance between your telescope and an accessory falls short. It is particularly useful with:
- CCD and CMOS cameras that need a precise optical path
- Field finderscopes with T2 connection
- T2 adapters and other accessories that require exact spacing
The rigid construction keeps all components perfectly aligned. There is no play, no wobble - everything stays on axis.
