Unfold the tripod, spread the legs, and push down the center arm.

Pivot the tripod tray so curved cutouts engage the tripod legs

Push the tray up from bottom and tighten the knob on threaded rod against bottom of tray.


Unlock the 3 tripod extension legs. Extend the tripod legs about 6-8 inches or more to give a comfortable viewing height for the scope. Gently tighten the locks.

IMPORTANT: Use the Bubble level mounted in the top of the tripod to level the tripod by adjusting the leg lengths as needed. Be sure to lock the leg locks firmly after leveling.




To make it easier to align a number of different Index marks on the Evolution scope, you can use white paint at the following locations:

1. paint a white mark at each screw location , on the side of the tripod head.

2. Paint a white mark on the 2 alignment Index bars on the side of the Azimuth base.

3. Put white paint on the Index marks of the Altitude head.

Loosen the Azimuth clutch knob and rotate the telescope head so the Index mark on the head lines up with the Motor index mark.

Gently tighten the Azimuth clutch,

Take the Evo Telescope head and place it on the top of tripod, centering the post of the tripod into the hole in the base of the head.

 Rotate the Evo  Azimuth head/motor so the 2 index white marks on the side line up with a white mark on the tripod.  It does not matter which tripod mark you line up.            

Gently push up on a screw knob under the tripod ,and turn it clockwise , making sure it is threading into  telescope base. You may have to rotate the base slightly clockwise or counterclockwise to engage the threads in the base. (Note:the screw is spring loaded)

Leave the screw somewhat loose. Do this for all 3 screws.

Then tighten them all firmly.


Loosen the Altitude clutch knob, by rotating it counterclockwise, (gold colored Disc).

Rotate the scope rail mounting slot so the rail slot is about 45deg from level. (cylinder with blue on it). Tighten the Altitude clutch knob. (clockwise)

Make sure the RAIL Lock Knob is loose enough to let the optics scope rail slide into the slot but not so loose that it will fall out of the slot. The knob should be pointed down toward the ground with the white Index mark towards the top .


Carefully pickup the Telescope optical tube and slide the rail into the rail slot in the Altitude head. Leave the rail sticking out about 3 inches past the slot (toward the eyepiece end) and tighten the RAIL Lock knob to lock the rail in place.


While holding onto the Telescope optic tube, Loosen the Altitude clutch and rotate the telescope so it is level to the ground. (Line up the white Index lines). Firmly tighten the clutch by rotating clockwise. Do not over tighten!

Remove the rubber cap on the back of the optic tube and thread on the Visual Back.

 Visual-back-star diagonal in scope

Loosen the set screws in the Visual Back, Insert the eyepiece Diagonal, and gently tighten the 2 set screws on the Visual Back to hold the Diagonal in place.


Take out an eyepiece , (in this case a Astrometric eyepiece), remove the lens cap and insert it into the Star diagonal.

Gently tighten the 2 setscrews on the eyepiece Diagonal to hold the eyepiece in place.

Mount your finder-spotter scope on the Optics tube mount. Two different types shown.


Remove the Telescope Front Lens cover by rotating it approx 1/4 inch counterclockwise and pull it off. See index mark on cover and telescope body.

IN COLD WEATHER, Install a optional dew shield over the front of the scope. Line up the cutout in the shield with the rail on the scope as you slide it in place. Slide it on evenly until it touches the rail.

Take the Starsense Camera and slide it all the way back onto the rail mounted on the side the Scope.

Firmly tighten the two set screws to lock the Starsense camera on the rail. The set screws should engage v-grooves in the side of the rail mount. This ensures a repeatable location if you remove and reinstall the camera.

Take the coiled cable from the StarSense camera and plug it into one of the AUX ports on the Altitude Arm. It can be either port.

Roughly balance the Optic Tube

Once all the hardware has been mounted on the optics tube , the Tube should be roughly balanced.

1. With the optics tube in a horizontal position.

While holding onto the Telescope optic tube, loosen the Altitude clutch and make a note of which end of the optics tube wants to pivot towards the ground. Re-Level the tube and Tighten the Altitude clutch.

2. While holding onto the Telescope optic tube, partially loosen the rail lock knob enough so you can slide the rail in the rail slot.

Slide the optics tube rail in the rail slot to move the "heavy" end (identified in step 1) towards the Rail lock knob approx 1 inch.

3. Tighten the rail lock knob.

Repeat steps 1-3 until the Optics tube does not rotate from level when you loosen the Altitude clutch.

Telescope Hand Controller Installation

Find the NexStar or STARSENSE Hand Controller and plug it into the base of the Azimuth  head. Use either port.

scope plugins-switch.jpg


Mount the Hand control saddle on one of the tripod legs. Place the hand control in the saddle.





Plug the charger into the charging port on the base of the mount. Then plug the charger into a outlet to charge the Evolution battery.

The charging indicator LED located below the Altitude Clutch Knob will light up.

The charge level is indicated by how fast the LED blinks.

charge led

Once the battery is fully charged the light will be on all the time or very slowly turn on/off.

Unplug the charger from the Telescope.





Before powering up the telescope system.

Verify that the Telescope optic tube is level to the ground.

 (Line up the white Index lines)

If not, while holding onto the Telescope optic tube, Loosen the Altitude clutch and rotate the telescope to Line up the white Index lines. Firmly tighten the clutch by rotating clockwise. Do not over tighten!

Verify that the Azimuth motor and head Index marks are aligned.

If not , loosen the Azimuth clutch, rotate until the index marks are aligned , then tighten the clutch.




Turn on the telescope by pushing the rocker switch.

The display of the Hand controller will light up and tell you when the control computer is ready.

The telescope is now ready for performing an alignment per the manual.




I have had an evolution 9.25 for 2 years so the information you have supplied is very helpful and concise and would recommend it to new Evo user.

Excellent.  Exactly the realistic and essential details that manuals and videos don't make clear!
