•Do not use telescope or finderscope to look at the sun without
an appropriate solar filter.
•Make sure no screws are loose before using telescope.
•Do not drop, shake, or throw your telescope as doing so may
damage the telescope or people around you.
•Objects in telescope may be farther away than they appear.
•Eyepieces intended for external use only.
•Don’t worry, be happy...
INTRODUCTION
Zhumell telescopes are precision astronomical instruments designed to be easy to use and versatile in their application. As
with any telescope, Zhumell telescopes require some technical
knowledge of stellar movement and optical properties. We have
tried to provide the basics of telescope use and astronomical
viewing in this manual. If, after reading through this manual,
you still have questions regarding the setup and use of your
telescope, please feel free to contact us at info@zhumell.com
or at (800)922-2063. Our customer service representatives will
be able to help address any problems you are having with your
Zhumell telescope. We also have more information available
on our website at www.zhumell.com. Please let us know about
your experiences with your Zhumell telescope. We would like to
hear your feedback and see your astrophotographs. Enjoy your
Zhumell.

CAREOFYOUR TELESCOPE
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 a mild soap solution
and soft, lint-free cloth. Do not rub elements when cleaning. Blot optical
components gently and allow telescope to air dry. Store telescope in box
when not in use. Do not use alcohol or solvents to clean any parts of the
telescope. Do not remove optical elements from telescope as doing so may
affect the alignment of optical components when reassembled. If telescope
needs realignment, contact Zhumell or another professional.
TELESCOPE ASSEMBLY
1. Extend tripod legs to comfortable working
height and tighten wingnuts to ensure stability. Separate tripod legs and ensure that the
legs are extended to equal heights. The top of
the tripod should be level to ensure stability
when mounting telescope.
2. Remove mount base screw. Insert bottom
of mount assembly into tripod mounting
hole. Replace mount base screw below tripod
mounting plate and tighten to secure mount
to tripod.
3. Loosen all setscrews on mount (except the
base screw) and position mount so that you
have access to all parts of the mount.
4. Find the latitude scale located on the side
of the mount above the base of the mount.
Remove the nut and washer located in the
center of the latitude scale. Slide clock drive
mounting bracket over the exposed bolt and
onto the raised fitting. Line up clock drive so
that the motor drive coil slides over the R.A.
adjustment shaft. The thumbscrew will need
to be loosened in order to ensure that the
motor drive coil slides easily onto the shaft.
Replace washer and nut to secure clock drive
assembly and tighten.
5. Loosen thumbscrews on R.A. and Dec.
adjustment cables. Slide shorter adjustment
cable over open end of the R.A. adjustment
shaft (opposite the mounted clock drive) and
tighten thumbscrew into notch on shaft. Slide
longer adjustment cable onto the Dec. adjustment shaft (below telescope mounting brackets) and tighten thumbscrew into notch.
6. Tighten all setscrews on the mount assembly to prevent movement of mount. Tighten
the set screw on the counterweight to prevent
movement of weight on balance shaft. Screw
threaded end of balance shaft into the threaded receptacle opposite the telescope mounting bracket on the upper part of the mount.
Tighten balance shaft for stability.
7. Remove wingnuts and washers from the
bottom of telescope mounting belt. Insert
exposed bolt into hole on top of mount.
Replace washers and wingnuts and tighten to
secure mounting belt. Repeat for each mounting belt.
8. Assemble optical tube assembly. Remove
thumbscrews on finderscope mounting bolts.
Slide finderscope mounting bracket onto
mounting bolts so that bracket is angled toward front of telescope. Replace and tighten
thumbscrews to secure bracket. Loosen
thumbscrews at top of finderscope mounting bracket. Slide finderscope into mounting
bracket with large end facing front of telescope. Tighten thumbscrews until snug.
9. Remove thumbscrews on top of telescope
mounting belts. Pull mounting belts open.
Place telescope in open belts so that the front
end of telescope faces away from the clock
drive unit. While holding the telescope in the
mounting belt, close belts and replace thumbscrews. Hand tighten thumbscrews to secure
optical tube assembly in mounting belts.
10. Screw eyepiece adapter onto the threaded
end of rack and pinion focusing mechanism.
Loosen thumbscrew on eyepiece adapter.
Place desired eyepiece into eyepiece adapter.
Tighten thumbscrew until snug to secure
eyepiece.
