Equipment and System Requirements

To charge your telescope’s battery, you will need:

  • An AC outlet to use with the supplied AC power adapter. (The adapter works with US, UK, EU, and AU format AC outlets.) If you would like to use the telescope’s wireless control feature in lieu of the provided StarSense hand control, you will need:
  • An Apple device running iOS 7.0 or later OR an Android device running Android 4.0 or later.
  • The Celestron SkyPortal app (available as a free download on the App Store and Google Play).

Solar Warning

  •  Never look directly at the Sun with the naked eye or with a telescope (unless you have the proper solar fi lter). Permanent and irreversible eye damage may result.
  • Never use your telescope to project an image of the Sun onto any surface. Internal heat build-up can damage the telescope and any accessories attached to it.
  • Never use an eyepiece solar fi lter or a Herschel wedge. Internal heat build-up inside the telescope can cause these devices to crack or break, allowing unfi ltered sunlight to pass through to the eye.
  • Never leave the telescope unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your telescope at all times, especially when children are present

Battery Caution

This product contains a long-life lithium-iron phosphate battery (LiFePO4). The battery includes numerous built-in safety features, including protection against overcharging, over discharging, and overheating. With proper use and care, the battery should last thousands of charge cycles without the need to replace it. To benefi t from the maximum battery life, note the following recommendations:

  •  Charge the battery to full as soon as you receive the telescope.
  • Only use the included power supply to charge the battery, or an FCC and CE certifi ed 12VDC power supply with at least 2 Amperes of current.
  • Do not leave the battery fully discharged or low for an extended period of time.
  • Every 3 to 6 months, fully recharge the battery.

Inserting the Battery into the Star Pointer Pro

The StarPointer Pro uses a CR-2032 button battery (included). To insert or change the battery, turn the StarPointer Pro over. The battery compartment is located in the center of the on/off/brightness switch. Use a coin in the slot on the cover to unscrew the cap counter-clockwise until the cap comes off. Insert the new battery with the Positive (+) side facing upward and screw the cover back on. If your StarPointer Pro does not immediately turn on, open the battery compartment to remove the small plastic disk that lies between the battery and the battery cover. This is used to prevent the battery from accidentally discharging during shipment.
If you are going to store your telescope for a long period of time, remove the battery to prevent corrosion.

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 silver ring clutch knobs and manually point the telescope to a distant object such as a streetlight, car license plate, tree top, or stop sign. (1000 yards or farther) during the day. NEVER point directly at the Sun! You can use a bright celestial object like the Moon, but we recommend choosing a stationary ground target.
  3. Using the 32mm 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.

Charging your Telescope Mount

The included AC adapter comes with international plugs. Select the plug that applies to your country and slide it into the body of the AC adapter until it clicks in place. Plug the AC adapter into the 12V DC power input on the base of the mount and plug the other end into a grounded wall socket. The logo light on the mount will slowly pulse to show that the battery is charging. When the light remains steadily lit, the battery is fully
charged and you are ready to observe. A completely drained battery can take 3 to 4 hours to fully charge.

Installing the Interchangeable Badges

Your 60th Anniversary Limited Edition NexStar Evolution 8HD with StarSense comes with interchangeable badges for the altitude clutch knob. These include the classic Celestron logo, the current Celestron logo and the 60th anniversary badge. Changing out the badges is simple. Slide your fi ngernail into the notch at the bottom of the installed badge and lift up. The badge is affi xed magnetically and will come off easily. Install the
new badge by lining up the notch with the register mark on the clutch knob and press it into place. Your telescope is now set up and ready to ali

Here’s how to quickly align your telescope for the fi rst 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”.
    CELESTRON NEXSTAR Evolution 8HD with Starsense User Guide  & troubleshooting 9
    Your NexStar Evolution generates its own WiFi network. You do not
    need WiFi or cellular service 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.

Please note the following for the most reliable WiFi connection to the telescope: Areas with high WiFi traffi c, such as large star parties or crowded public spaces, can potentially pose diffi culties connecting to the telescope. Additionally, multiple smart devices and multiple WiFi telescopes in the same area can generate confl icting traffi c. Follow these tips to maintain the most robust connection to your telescope

  1. If you experience lag or connection problems in areas with high WiFi traffi c–To minimize possible connection problems in high traffi c areas, select a viewing site with minimal WiFi traffi c. Numerous nearby devices with WiFi enabled can contribute to unwanted WiFi traffi c. Disabling WiFi in nearby devices can improve connectivity to your telescope. Alternatively, high traffi c areas may require the use of the included NexStar+ hand control instead of the SkyPortal app over WiFi.
  2.  If you experience confl icts when using multiple devices to control a telescope–If you have multiple smart devices, and have connected to the same WiFi telescope previously with them, both devices may unintentionally communicate with the telescope at the same time. For example, if you have previously used your smartphone to control the telescope and later use a tablet to control the same telescope, the smartphone may interfere with the telescope connection. We recommend “forgetting” the telescope WiFi network with any smart devices not currently in use.
  3. If you experience confl icts when multiple WiFi telescopes are in the same area–If you are using multiple WiFi telescopes and have connected to them with your smart device previously, we recommend “forgetting” the other telescopes/devices not currently in use. This way, you won’t accidentally connect to the other telescopes/devices. This is especially useful at a star party where more than one WiFi telescope may be in range.

StarSense is aligned, but there’s just one fi rst-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 fi eld 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 fi rst time you are using StarSense with the telescope in SkyPortal.

Congratulations! You are now aligned and ready to observe.
Tap objects on your screen and select GoTo or search for a specifi c object in the search fi eld. To start, you can choose from the “Tonight’s Best” list in SkyPortal under the Search menu.

Important Information About Your 8” EdgeHD Optical Tube Assembly

Your EdgeHD optical tube is optimized for both visual astronomy and astrophotography, delivering images free of coma or fi eld curvature across a large image circle. Start by using the supplied Star Diagonal and eyepieces to familiarizeyourself with the telescope

Primary Mirror Clutch Knobs (for Astrophotography Only)

The primary clutch knobs hold the mirror in place to prevent movement during a long exposure astroimage. Keep these loosened unless you are using a camera for long exposures. When using a camera, focus the telescope fi rst, then tighten the knobs. Warning: Do not turn the focus knob with the clutch nobs tightened. Anytime you refocus the telescope, loosen the clutch knobs.

Optimum Camera Distance

The 8” EdgeHD was designed to work with your camera at a specifi c distance from the end of the threads on the back of the scope to the camera’s sensor.

CELESTRON NEXSTAR Evolution 8HD with Starsense User Guide  & troubleshooting 10

          Edge HD 8”- Optimum Back Focus Distance

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 8” 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 133mm. 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 78mm of spacing to reach 133mm.

Fastar Compatibility and Imaging at f/2

CELESTRON NEXSTAR Evolution 8HD with Starsense User Guide  & troubleshooting 11

Your 8” EdgeHD 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. 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 8” 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 13mm 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.
    CELESTRON NEXSTAR Evolution 8HD with Starsense User Guide  & troubleshooting 12

A defocused star where the secondary shadow is not concentric to the star pattern indicates the telescope requires collimation.
