CARING FOR YOUR
ZHUMELL TELESCOPE
Zhumell telescopes are precision astronomical instruments designed
for ease of use and versatility in their application. As with any telescope,
Zhumell telescopes require some technical knowledge of stellar
movement and optical properties. We have provided basic instructions
for telescope use and astronomical viewing in this manual.
Your Zhumell 50mmx360mm telescope is built with the highest
quality optics and top-notch construction to provide years of reliable
functionality, but will require proper care.
Enjoy your Zhumell.
