Telescope Optical Tube

The 6” optical tube is preinstalled with the telescope. The 8”

and 9.25” models require installing the optical tube onto the

fork arm mount.

1. Unlock the altitude clutch by loosening the orange altitude

clutch lock knob.

2. Rotate the altitude axis until the quick release knob faces

downward.

3. Tighten the altitude clutch lock knob.

4. Loosen the quick release knob a couple of turns to allow

room for the dovetail on the telescope optical tube.

5. Slide the telescope optical tube into the quick release slot

from the back side of the telescope. The fork arm should

be on the left side of the optical tube. For correct balance,

position the telescope so that you can read the “Evolution”

nameplate. If you choose to add different accessories to

your telescope, you can rebalance it later.

6. Keep hold of the optical tube and secure it into place by

tightening the quick release knob.

Visual Accessories

Star Diagonal

The included star diagonal diverts the light at a right angle

to the light path of the telescope. This allows you to observe

in positions that are physically more comfortable than if you

looked straight through. Note that images observed through

a right angle star diagonal are right-side-up, but mirror inverted.

Eyepiece

The eyepiece is the optical element that magniﬁes the image

focused by the telescope. The eyepiece ﬁts into the star diagonal.

Two eyepieces are included with the NexStar Evolution. You

should always start with the lower power 40 mm eyepiece to

ﬁnd and center objects.

Remove all the dust caps from the star diagonal, 40 mm eye-

piece, and the dust cap on the visual back of the telescope.

Eyepiece and Diagonal

1. Insert the mirror star diagonal into the visual back of the

telescope and secure it into place by tightening the two

set screws on the visual back.

2. Insert the 40 mm eyepiece into the mirror star diagonal

and secure it into place by tightening the two set screws

on the diagonal.

StarPointer Red Dot Finder

1. Loosen the two Phillips head screws on the StarPointer’s

dovetail clamp slightly using a screwdriver.

2. Slide the StarPointer over dovetail rail preinstalled on the

telescope. (See StarPointer Overview)

3. Tighten the two Phillips head screws to secure the ﬁnder

in place.

Aligning the StarPointer Red Dot Finderscope

The StarPointer is powered by a long life 3-volt lithium bat-

tery (#CR2032) located underneath the front portion of the

Star Pointer. The StarPointer must be properly aligned with

the telescope before it can be used. This is a simple process

using the azimuth and altitude control knobs located on the

side and bottom of the StarPointer. The alignment procedure

is best done at night since the LED dot will be difﬁcult to see

during the day.

1. Turn on the StarPointer by rotating the variable brightness

control clockwise until you hear a click. To increase the

brightness level of the red dot, continue rotating the con-

trol knob about 180º until it stops.

2. Locate a bright star or planet and center it using the

40 mm eyepiece in the telescope.

3. With both eyes open, look through the glass window in

the StarPointer.

4. If the StarPointer is perfectly aligned, you will see the red

LED dot overlap the alignment star. If the StarPointer is

not aligned, take notice of where the red dot is relative to

the bright star.

5. Without moving the main telescope, turn the StarPointer’s

azimuth and altitude alignment controls until the red dot is

directly over the alignment star.

The Altitude and Azimuth Clutches

NexStar Evolution features manual clutches that allow you to

manually move the altitude (up/down) and azimuth (left/right)

axis without using the motors. This can be useful for daytime

terrestrial use or when storing the telescope.

Note: You should not unlock the clutches when the telescope

is aligned with the app or hand control, or the alignment will

be lost. The telescope accounts for movement made by the

motors. If the telescope is moved manually or bumped after

it was aligned, you should perform a new alignment.

This is the recommended starting position of the telescope,

but is not required:

1. Unlock the altitude clutch knob and position the telescope

so that it’s perpendicular to the fork arm base, then retight-

en the altitude clutch knob.

2. Unlock the azimuth clutch knob and position the telescope

so that it’s aimed towards an unobstructed horizon, then

retighten the azimuth clutch knob.

The WiFi and Reset Switches

WiFi can be toggled between Direct Connect and Access

Point modes. A small ﬂat head screwdriver or ballpoint pen

can be used to access the switch. Direct Connect is used

to connect directly to your smart device. Access Point mode

is used to connect to your home network through a router.

Refer to Appendix B, Advanced WiFi for more information.

The WiFi switch should always be in the UP position

for normal use.

The reset switch can be accessed using a ballpoint pen.

The reset switch should normally not be used except in the

unlikely event the telescope becomes unresponsive after

cycling the power switch.

Getting Started – Using Your

Smart Device

Now that your telescope is assembled and the StarPointer

is aligned, let’s connect it to your smartphone or tablet. We

recommend you familiarize yourself with the telescope and

app during the day before using it at night.

Caution: Remember to never point the telescope at the Sun

during the day without using a proper full aperture solar ﬁlter!

1. Turn the power switch to the ON position (ON=1 OFF=0).

The Celestron logo LED will light up indicating the tele-

scope is on. The WiFi LED will also blink indicating WiFi

ready status.

2. Go to your device’s WiFi settings, and connect to the

“SkyQLink-xx” network that your telescope is broadcasting.

Wait for your device to conﬁrm that you have successfully

connected.
