This is an excellent 1.25-inch double-threaded focuser with a 10mm adjustment stroke. It is light and compact, made of all metal, and durable.

During the focusing process, the inserted CDD eyepiece or zenith mirror remains non-rotating and only makes linear movements, which is conducive to observation and astronomical p ography.

The meticulous craftsmanship makes its micro-focusing extremely precise, and it remains smooth and stable even at huge magnifications.
