Assembly

For the 114mm and 130mm models:

1. Connect the side support (B2) to the side panel (B1) with the base assembly screws (B5). The supports go on the on the same side of the panels as the Electron logo.
   

For the 150mm model:

1. a. Connect the 2 side supports (B2) to the side panel (B1) with the base assembly screws (B5). The supports go on the on the same side of the panels as the Electron logo.
   

2. If desired, you can install the cosmetic screw covers (B6) on the screws installed in Step 1. Press the covers firmly onto the screw heads. For the 114mm and 130mm models there will be 2 screw covers to install, for the 150mm model there will be 6 screw covers to install.
   

3. Connect the assembly to the top plate (B3) using the base assembly screws (B5). Orient the top plate so the side with the logo faces upward. For the 114mm model there will be 4 screws to install, for the 130mm and 150mm models there will be 5 screws to install.
   

4. Attach the 3 tripod adapter discs (C1) to the bottom plate (B4) using the tripod adapter screws (C2). Thread the screws firmly into the perilled pilot holes but do not over tighten or you may strip the wood.
   

5. Attach the 3 feet (D1) to the bottom plate (B4) using the feet screws (D2). Thread the screws firmly into the perilled pilot holes. Once installed, press the feet screw covers (D3) onto the ends of the feet.
   

6. Connect the assembly to the bottom plate (B4). Place one of the steel washers (E2) and the plastic cylinder (E4) onto the bolt (E5). Then, insert the bolt through the central hole in the bottom plate. Next, place the Teflon washer (E3) over the plastic cylinder (E4) now protruding from the bottom plate.
   Take the assembled base and lower it onto the bottom plate so that the plastic cylinder goes through the central hole in the top plate. Now, place the remaining steel washer (E2) on the end of the bolt protruding from the top plate. Thread the nut (E1) onto the bolt. Go to Step 7 for instructions to tighten the bolt.

7. Use the crescent wrench and large hex key to tighten the nut onto the bolt. Hold the head of the bolt stationary with the hex key while using the crescent wrench to tighten the nut. DO NOT OVER TIGHTEN THE NUT! With some force, you should still be able to move the steel washer underneath the nut with your fingers. If the washer cannot be moved with your fingers, slightly loosen the nut.

8. Install the eyepiece rack (F1) by placing the keyholes in the rack over the mounting screws pre-installed in the side panel, then push the rack downwards.
   NOTE : If you want to remove the rack for storage or transport, simply pull it upward.

For the 114mm model:

9. Connect the optical tube assembly (A) to the assembled base.Fully thread the clamping knob on the cradle and open the cradle. Place the optical tube in the cradle as shown, close the cradle, and re tighten the clamping knob until secure.

For the 130mm model:
b. Loosen the knob on the dovetail holder on the side panel.
Then, insert the dovetail connected to the optical tube with the tube rings, and re tighten the knob until the dovetail is secure in the holder.

For the 150mm model:
c . Connect the optical tube assembly (A) to the assembled base.You’ll need to connect the tube rings to the tube ring mounting plate on the base. Use the screws and lock washers already installed in the rings to do this. It will be easiest to first remove the rings from the optical tube to assemble them onto the mounting plate. Fully thread the tube ring knobs and open the rings to remove the tube.

10. Install the Star Sense dock (G). Insert the bayonet mount on the side of the dock into the port on the side panel of the base.
    

11. Line up the arrow on the dock with the alignment mark on the base and press inward while turning the dock counterclockwise until the orange release button snaps into place in the hole on the dock. To remove the dock, press the orange release button and turn the dock clockwise until the bayonet mount releases.
    
    For the 114mm model:
    

12. a. Install the Star Pointer red dot finder scope (H) onto the optical tube assembly. First, thread and remove the two thumb nuts from the threaded posts adjacent to the focuses.
    Place the Star Pointer on the tube so the threaded posts go through the holes in the Star Pointer’s base, then retread the thumb nuts onto the posts to secure the Star Pointer.
    
    For the 130mm and 150mm models:
    b. Install the Star Pointer red dot finder scope (H) onto the optical tube assembly. First, loosen the thumbscrew on the finder scope holder. Insert the base of the Star Pointer into the holder and tighten the thumbscrew.
    

13. Loosen the thumbscrews on the end of the focuses, remove the focus’s cover cap, and insert the 25 mm (or 17mm) eyepiece. Re tighten the thumbscrews on the focuses to secure the eyepiece in place.
    

Downloading and Activating the App

Before you take your telescope outside, download the Star Sense Explorer app to your mobile device.
Search for “Electron Star Sense Explorer” in the Apple App Store or Google Play. The app is large, so we recommend downloading it while connected to Wi- Fi.

Once you have downloaded the app, locate the orange postcard in your telescope box. Launch the app. When prompted, enter the activation code on the postcard to activate the app. Your code will unlock up to 5 devices.

Balancing the Telescope

For best altitude (up-and-down) motions, the telescope optical tube should be roughly balanced on the base.

1. To check balance, loosen the altitude pensioning knob so the altitude axis moves freely. Note if the telescope wants to tilt forward (front-heavy) or back (back-heavy).
   

2. Loosen the tube ring knobs (130mm and 150mm models) or tube clamp knob (114mm) and slide the telescope forward or back in the rings/clamp so it is balanced. Re tighten the knob(s) when done.
   

Moving the Telescope

The Star Sense Explorer Tabletop Obsidian telescope moves freely in altitude (up-and-down) and azimuth (left-to-right)

1. Simply move the tube by pushing it in the desired direction. For the 150mm model, you can use the knob handle at the front of the telescope for a hand grip.
   

2. If the altitude motion moves too freely, or the telescope moves up or down with no force being applied, tighten the altitude pensioning knob. Conversely, if it takes much force to move the telescope upwards or downwards, loosen the knob.
   

Attaching the Smartphone

1. Remove the large cap covering the mirror on the front of the Star Sense dock.
   

2. Pull open the spring-loaded slider on the top of the phone dock and set the phone into the holder so it is flush with the bottom lip of the phone holder. Slowly release the slider to secure the phone in place.
   

Aligning the Star Pointer

The Star Pointer red dot finder scope is one of the most important parts of your telescope.
Although the Star Sense Explorer app will locate and centre objects for you, having the Star Pointer properly aligned will help you align the app to the telescope. The first time you assemble your telescope, you need to align the finder to the telescope’s main optics. It’s best to do this during the day

*SOLAR WARNING!** Never attempt to view the Sun through any telescope without a proper solar filter!

1. CHOOSE A TARGET
   Take the telescope outside during the day and find an easily recognisable object, such as a streetlight, car license plate or sign. The object should be as far away as possible, but at least a quarter mile away.
   

2. CENTRE THE TARGET IN THE EYEPIECE
   Look through the telescope using the 25mm (17mm for the 114 model) eyepiece. Move the telescope until the object you chose lies in the centre of the view. If the image is blurry, gently turn the focus knobs until it comes into sharp focus.
   NOTE : The image in your telescope may appear inverted. This is perfectly normal in an astronomical telescope.
   

3. LOOK THROUGH FINDERSCOPE
   Pull the battery protection tab out of the Star Pointer and turn it on to maximum brightness using the on/ off knob. Look through the Star Pointer and locate the red dot.
   

4. ADJUST THE FINDER SCOPE
   Without moving the telescope, use the two adjustment knobs to move the red dot until it appears over the same object you are observing in the telescope’s low-power eyepiece.
   

5. YOUR FINDER SCOPE IS NOW ALIGNED!
   It should not require realignment unless it is bumped or dropped. Now, when you look through the Star Pointer, the red dot will indicate where the telescope is pointing. Don’t forget to turn off the red dot when you are finished to conserve battery.
   

Your First Night Out

Congratulations! Your telescope is now set up and you are ready to explore the cosmos. Take the telescopeoutside, insert your 25mm eyepiece (17mm for the 114 model), remove the lens cap, insert your smartphone into the holder, and launch the Star Sense Explorer app. The tutorial in the app will walk you through the steps to find your first astronomical target.
