How to Use this Quick Setup Guide

Refer to this guide to get your telescope setup and aligned

with StarSense and the SkyPortal app using your smart

device. Here you will also ﬁnd useful information about the

EdgeHD optical tube assembly and different options for

astrophotography. From there, refer to the full NexStar

Evolution and StarSense manuals included with your tele-

scope for more advanced settings options, including usage

of the StarSense hand control.

Note that the NexStar Evolution manual refers to

Schmidt-Cassegrain optical tubes and the NexStar+ hand

control which are not part of your telescope. The key

differences in your telescope are the 9.25” EdgeHD optical

tube, StarSense AutoAlign camera, and StarSense hand

control.

Attach the Mount to the Tripod

1. Position the fork arm mount over the center post on the

tripod head. Do not let go of the mount until it has

registered with the center post. The mount should not

wobble.

2. With the mount resting on the tripod head, rotate the

mount until the three mounting sockets align. The

sockets will click into place, indicating they are aligned.

3. Thread the three captive mounting bolts from underneath

the tripod head into the bottom of the telescope base.

Attach the Telescope to the Mount

1. Loosen the orange altitude clutch lock knob and rotate

the altitude axis until the quick release knob faces

downward.

2. Tighten the altitude clutch lock knob.

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

room for the dovetail on the telescope optical tube.

4. 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

Attach StarSense to the Telescope

1. Partially thread the two nylon-tipped thumbscrews

(included in the StarSense box) onto your StarSense

camera bracket.

2. Slide the StarSense camera onto the mounting bracket

on the telescope. Lock both thumbscrews.

3. Plug the supplied coiled cable into the StarSense

camera and one of the 4 aux ports located on the fork

arm.

Insert the Star Diagonal and Eyepiece

1. Insert the Star Diagonal into the 1.25” visual back of your

telescope and tighten the thumbscrews.

2. Insert the 25mm Plössl eyepiece into the Star Diagonal

and tighten the thumbscrews.

Attach and Align the StarPointer Pro

to the Telescope

1. Slide the StarPointer Pro over the dovetail base on your

telescope and tighten the two silver thumbscrews to lock

it in place.

2. Loosen the two orange ring clutch knobs and manually

point the telescope to a distant object (1000 yards or

more) during the day (NEVER point directly at the Sun!).

You can use a bright celestial object like the Moon, but

it’s easier initially to pick a stationary ground target.

3. Using the 25mm eyepiece, focus the telescope on the

object by turning the focus knob. Ensure the object is

centered.

4. Turn the StarPointer Pro on to full brightness to view the

bullseye. Center the bullseye over your target using the

up/down and left/right adjustment knobs.

Note: Remember to turn the StarPointer Pro off after each

usage to preserve battery life.

Your telescope is setup and ready to align! Here’s

how to quickly align your telescope for the ﬁrst time

1. Power the scope on and connect to its WiFi network

from your phone or tablet. The WiFi network name will

begin with “Celestron-XX”.

Your NexStar Evolution generates its own WiFi network,

you do not have to be connected to anything else to use

the telescope.

2. Open SkyPortal, tap the scope icon, and tap “Connect

and Align”. Follow the on-screen prompts and StarSense

will automatically align your telescope.

StarSense is aligned, but there’s just one ﬁrst-time-

only step before you’re ready to go: Calibrate the

camera to the telescope.

3. After the StarSense alignment is complete, select a

bright star in SkyPortal by tapping it on the screen, then

tap “GoTo”. If the star is not in the eyepiece’s ﬁeld of

view, start by centering it in the StarPointer, then center

it in the eyepiece.

With the star centered in the eyepiece, tap Align, then

tap Calibrate. Once the camera is calibrated, follow the

prompts to start a new StarSense Auto alignment. You

only need to do this the ﬁrst time you are using

StarSense with the telescope in SkyPortal.

Installing & Using The Barlow Lens

Your telescope also comes with a 2x Barlow lens which

doubles the magnifying power of each eyepiece. To use the

Barlow lens, insert the Barlow between the diagonal and

the eyepiece.

Note: Start by using a low power eyepiece as it will be

easier to focus.

Installing The Moon Filter

To use the moon ﬁlter, simply thread the ﬁlter to the chrome

barrel of the eyepiece.

Aligned and Ready to Observe!

Tap objects on your screen and select GoTo, or search for

a speciﬁc object in the search ﬁeld. To start out, you can

choose from “Tonight’s Best” list in SkyPortal under the

Search menu.

Important Information About

Your Edge HD 9.25” Optical Tube

Assembly

Your EdgeHD is optimized for both visual astronomy and

astrophotography, delivering images free of coma or ﬁeld

curvature across a large image circle. Start by using the

supplied 1.25” visual back, Star Diagonal, and eyepieces

to familiarize yourself with the telescope.

Primary Mirror Clutch Knobs

(for Astrophotography Only)

These clutch knobs (shown in overview image) hold the

mirror in place to prevent movement during a long exposure

astrophoto. Keep these loosened unless you are using a

camera for long exposures.

When using a camera, focus the telescope ﬁrst, then

tighten the knobs.

Warning: Do not turn the focus knob with the

clutch knobs tightened. Anytime you refocus the

telescope, loosen the clutch knobs.

Optimum Camera Distance

The 9.25” EdgeHD was designed to work with your camera

at a speciﬁc distance from the end of the threads (of the

adapter plate shown in the diagram) on the back of the

scope to the camera’s sensor.

If you are using a DSLR, the distance is already set

correctly when you use these standard adapters available

from Celestron:

T-ring for the make and model of your camera

T-adapter for 9.25” EdgeHD

If you are using an astronomical CCD camera, you must

determine the necessary adapter length to the camera

body.

The total distance from the end of the adapter plate

threads to the camera sensor should be 146mm.

This is the total required backfocus distance. Your camera

body to the imaging sensor will take up some of this

backfocus distance. Your camera manufacturer will usually

specify the camera backfocus distance. For example, if your

camera’s backfocus distance is 55mm, then you will need

91mm of spacing to reach 146mm.

ENGLISH I 11

Your EdgeHD 9.25” is equipped with a removable

secondary mirror that allows you to convert your f/10

telescope into an f/2 imaging system using an optional lens

accessory made by Starizona. This adds versatility to use

the telescope at different focal ratios for astrophotography.

Imaging at f/2 is favored for wide-angle deep sky imaging

with short exposures, well suited to large deep sky objects.

Optional Focal Reducer

A dedicated 0.7x Focal Reducer for the 9.25” EdgeHD is

available from Celestron. This focal reducer maintains the

ﬂat-ﬁeld and coma-free imaging performance speciﬁcally

designed for this telescope.

Collimation

Your telescope is factory aligned and generally should not

need collimation unless it is transported roughly. However,

you should be aware of the eventual need to collimate your

telescope to keep it operating at peak performance.

1. Using your included 25mm eyepiece (or a higher power

eyepiece if you have one), point the telescope at a

moderately bright star center it in the eyepiece.

2. Defocus the star about 1 turn on the focus knob.

3. Inspect the star pattern. When collimated, the pattern

should look like a concentric doughnut. If the pattern is

concentric, no adjustment is necessary.

4. Adjust the telescope collimation if needed by slightly

adjusting the 3 Phillips head screws in front of the

secondary mirror.

5. If the star pattern is thin on one side, adjust the

collimation so that the star moves towards the thin side,

then adjust the position of the telescope to re-center the

star. Repeat this until you achieve correct collimation.

Secondary Mirror Collimation Adjustment Screws

A defocused star where

the secondary shadow

is not concentric to the

star pattern indicates

the telescope requires

collimation.

The telescope is

collimated if the

defocused star pattern is

concentric as shown.
