Product Information
The 114mm Newtonian Reflector Telescope is a powerful telescope designed for observing celestial objects. It is equipped with various components to enhance your viewing experience.
Instruction Manual
WARNING
NEVER USE A TELESCOPE TO LOOK AT THE SUN
Looking at or near the Sun will cause instant and irreversible damage to your
eye. Children should always have adult supervision while observing.

Telescope Setup
The N114 telescope comes with a Vixen-type dovetail. It can be mounted onto any telescope mount that accepts a Vixen-type dovetail. Just simply release the dovetail locking knob on the dovetail saddle. Slide the telescope dovetail bar in and lock the dovetail locking knob.
Figure 2. Install the N114 telescope onto a telescope mount Attach the red dot finder scope to the telescope tube.
Figure 3. Install a red dot finder.
First remove the two thumb nuts from the scope body. Then place the finder
scope onto the two bolts and re-attach the nuts. The finder scope should face
towards the open end of the telescope (see arrow in diagram).
Insert the diagonal into the eyepiece side of the telescope. Tighten the
thumbscrews to a firm feel only. Slide the eyepiece into the open end of the
diagonal. Tighten the. Remove the dust cover from the other end of telescope
before observation.
Telescope Operation
Imaging Orientation
The image orientation of in an N114 scope is inverted, as shown in the
following. The image is upside-down and reversed from left-to-right. Practice
your telescope mount on the moving directions during the day time. actual

Selecting an Eyepiece
The magnification of a telescope is defined by the focal lengths of the
telescope and the eyepiece. A formula can be used to determine the power of
each eyepiece: Telescope focal length divided by eyepiece focal length equals
magnification.
For example, an N114 telescope has a focal length of 1000mm. With a 25mm
eyepiece, the magnification will be 1000mm ÷ 25mm = 40X (magnification)
If you want more magnification, you may order higher power eyepieces. Note: a
25 mm focal length eyepiece has a lower power than a 10 mm one. Always start
with the lowest power eyepiece for easy locating the objects.
Focusing Telescope
Practice telescope focusing during the daytime to get familiar with the
scope.
After selecting the desired eyepiece aim the telescope tube at a land-based
target at east 200 yards away (e.g. A telephone pole or building). Fully
retract focusing tube by turning the focus knob.
While looking through selected eyepiece, slowly extend focusing tube by turning focusing knob until object comes into focus.
Using Finder Scope
Check the LED battery on the finder. The finder uses a CR2032 Lithium
button battery. Slide a new battery into the battery compartment with “+” sign
facing out. Turn on the switch on the side of the finder. You should see a red
dot on the front screen. There are two thumb screws on the finder to adjust
the red dot position on the screen. The one on the bottom is for up/down, and
the one on the side is for left/right Aim the telescope to a distant object
and center it in the eyepiece. The look through the red dot finder and adjust
two thumb screws to move the red dot pointing to the object. If the red dot
can’t reach the alignment object in laft/right direction, adjust the finder by
release two thumb nuts shown in Figure 3. Mow you have the red dot finder
aligned to the main telescope. Use the red dot to find the object and it
should also located into your main scope.
