1.25 Inch Astronomical Telescope Helical Focuser Aluminium Alloy Helical Fine Tuning High Precision Focuser for Astronomy Telescope
Product Introduction:
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 photography. The meticulous craftsmanship makes its micro-focusing extremely precise, and it is still smooth and stable even at huge magnifications.
