Design and durability

Introduction:
- This is an excellent 1.25-inch double threaded focuser with a 10mm focusing stroke, lightweight and compact, all metal manufacturing, sturdy and durable. The CDD eyepiece or zenith mirror inserted during the focusing process remains non rotating and only performs linear motion, which is beneficial for observation and astronomical photography. The finely crafted production process makes its micro focusing incredibly precise, even at huge magnifications, it remains smooth and stable.
