Assembly Guide : 90mm Cassegrain with iOptron
INTRODUCTION
Congratulations! You have bought a wonderful telescope. This is a precision optical instrument, and
you have many wonderful evenings of observing the night sky ahead of you. This guide is to help
you assemble your telescope properly.
We know that many people are visually oriented and that pictures of the assembly process are help-
ful. We have put this guide together to help you assemble your telescope for your first night of ob-
serving.
Once your telescope is assembled and ready to go, the rest is up to you. Learning astronomy is all
the fun anyhow! So let's get started . . .
ASSEMBLING THE TELESCOPE
Step 1 Attach the iOptron SmartStar Cube to
the tripod as shown in Figure 1.

Step 2 Attach the Accessory tray to the tripod
as shown in Figure 2.
Figure 2 – Attaching the Accessory Tray.
Step 3
Your 90mm telescope needs a “dovetail
mounting plate” attached to the bottom.
Sometimes, the plate will come pre-
attached to the telescope. You may skip
this step if your mount plate is pre-
attached. Other times, you may have to
attach the plate yourself. It’s easy. Using
a screwdriver, simply attach the dovetail
mounting plate to the bottom of the tele-
scope. Be sure the long end of the mount
plate is oriented to the front of the tele-
scope as shown in Figure 4

Star tripod and mount.

Step 5
Figure 5 – Attach the telescope to the mount.
Once the mounting plate is attached to
the telescope, simply slide the assem-
bled telescope right into mount and lock
it in place with the set screw as shown
in Figure 5.
Next, you can attach the optional sighting
scope to the main telescope as shown in
Figure 6
Step 6

tached to the telescope tube.
Step 7
Figure 7 – The angle prism screws into
the telescope tube.
The angle prism screws into the back of
the telescope tube as shown in Figure
7.

Step 8 Finally, insert one of your eyepieces
into the back of the angle prism, as
shown in Figure 8, and you are ready to
begin observing. Be sure to tighten the
set screw that holds the eyepiece in
place.
Thanks again for your business. We hope you enjoy your new
telescope!

prism. Be sure to ghten the silver set screw.
Step 9 Check the flip mirror switch. This
switch lets you choose to observe
through the back of the telescope or the
top of the telescope. To observe using
the back of the telescope, the switch
should be oriented parallel to the tele-
scope tube, as shown in Figure 9.
Figure 9 – The flip mirror is set so that
the image can be seen through the back
of the telescope.
