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 Aurora 70 Refractor Telescope is built with the
highest-quality optics and top-notch construction to provide
years of reliable functionality, but will require proper care.
If, after reading this manual, you still have questions about
your Zhumell telescope, please visit http://www.zhumell.com
for more helpful tips and contact information. Our customer
service representatives are available to address any problems
you encounter with your telescope. Please let us know about
your experiences; we would like to hear your feedback.
Enjoy your Zhumell.

WARNINGS
• Do not use telescope or finderscope to look at the sun without
an appropriate solar filter. Doing so will cause permanent and
irreversible eye damage.
• Never use an eyepiece filter as a solar filter. Only solar filters will
completely cover the opening of the optical tube and provide
proper eye protection.
• Make sure no screws are loose before using telescope.
• Do not drop or shake your telescope as doing so may damage
the optics, or harm you or the people around you.

ZHUMELL AURORA TELESCOPE
CLEANING AND MAINTENANCE
A telescope is carefully aligned during construction, and great care should
be taken to maintain this alignment over the life of the telescope. Cleaning
should be done as little as possible and then only with mild soap solution
and a soft, lint-free cloth. Do not rub elements when cleaning. Blot optical
components gently and allow telescope to air-dry. Store telescope in its box
or in a telescope case when not in use. Do not use pure alcohol or solvents
to clean any parts of the telescope. Do not remove optical elements from the
telescope as doing so may affect the alignment of optical components
when reassembled. If telescope needs realignment, contact Zhumell or
another professional.
1. Brush telescope optics with camelhair brush or blow off dust with an ear
syringe (can be purchased at any pharmacy). Do not use a commercial
photographic lens cleaner.
2. Remove organic materials (e.g. fingerprints) with short gentle strokes using
soft white tissue paper and a solution of three parts distilled water and
one part isopropyl alcohol. You may also add one drop of biodegradable
dish soap to one pint of the homemade solution. Do not use lotioned or
scented tissues as they could damage the optics of your telescope.
3. Wipe down the outside of your telescope with a dry cloth to remove
condensation prior to packing up your telescope. Do not wipe any of the
optical surfaces. Instead, allow the optics to dry naturally in warm indoor
air prior to packing up your telescope.
4. Protect your telescope from excessive heat. For example, do not
store your telescope in a sealed car on a warm day. Excessive storage
temperatures can damage your telescope.

TRIPOD ASSEMBLY
STEP 1: Spread out the Tripod legs so that it can stand on its own. Attach the Accessory Tray to the three
connection points on the Tripod legs. Tighten using the thumbscrews on the attachment points.
STEP 2: Extend each leg one at a time using the large screws at the midpoint of the leg. Tighten each leg
at a height where you will be able to stand comfortably during the rest of assembly (just above waist-high).
Make sure they are tightened evenly so that the top of the Tripod is parallel to the ground.
ATTACHING THE EQUATORIAL MOUNT
STEP 1: Remove the Base Mount Screw from the bottom of the mount, leaving the attached washer in place.
Insert the mount into the hole in the middle of the tripod, and tighten underneath using the Base Mount Screw.
