36.4mm Male Thread Eyepiece Adapter

This adapter connects a 1.25" eyepiece to a telescope or microscope using a 36.4mm male thread. It suits astronomers and microscopists who need a secure mechanical link between their instrument and standard eyepieces. The adjustable optical length ranges from 29 to 35.5mm for fine focus tuning. Baader Planetarium construction provides a precise fit for reliable long-term use.

Check Thread And Eyepiece Size Before Ordering

Verify that your telescope or microscope accepts a 36.4mm male thread on the instrument side. Confirm that the eyepiece you intend to use has a 1.25" barrel diameter. The adjustable optical length spans 29 to 35.5mm, so ensure this travel range matches your focuser requirements. No other thread sizes or eyepiece diameters are supported by this adapter.

All-Metal Build Runs Cool And Silent

The all-metal housing has no moving parts, fans or electronics, so it generates no heat and produces no noise during observation. Power draw is zero because the adapter is purely mechanical. Its robust construction maintains alignment without thermal drift. The unit adds minimal mass to the optical train while preserving image stability.

Questions about this item

Does the 36.4mm male-thread adapter ship with any 1.25" eyepieces or must they be purchased separately?

Only the adapter is supplied; 1.25" eyepieces are sold separately.

How do I decide which adjustable length setting between 29mm and 35.5mm suits my telescope?

Start near the middle of the 29-35.5mm range and rotate the barrel until the image reaches sharp focus.

What does the 36.4mm male thread specification mean when the adapter is fitted to my telescope?

It matches the 36.4mm female thread on compatible focusers, giving a rigid, vibration-free join for 1.25" eyepieces.
