Place the two holes in the base of the finderscope
over the threaded posts so the finderscope base
sits flush on the telescope tube. Make sure that the
round window on the finderscope is pointed away
from the focuser.
Thread the two nuts back onto the threaded posts.
There is a small clear plastic tab inserted between the
battery and the contact. This was included to prevent
the battery from discharging during shipment. Pull
this out to allow your battery to work.
To use the Barlow lens, remove your eyepiece
from the telescope focuser, insert the Barlow lens
into the focuser and insert your eyepiece into the
Barlow lens. This will double the magnification of
whatever eyepiece you use it with.
Loosen the setscrews on the telescope focuser and
remove the dust cap.
To install the eyepiece, loosen the setscrews on the
focuser. Insert the silver barrel on the bottom of the
eyepiece into the focuser and secure by tightening
the setscrews. Always start using your low-power
eyepiece (25 mm) to help you find the target you
wish to view. You can always change to your high-
power eyepiece (10 mm) later.
To install the StarSense smartphone dock, loosen
the two setscrews on the dock mount on the top
of the telescope tube and slide the dovetail on the
bottom of the dock into the mount. Secure in place
by tightening both screws.
Remove the lens cap from the front of the telescope.
To observe, look through the eyepiece as shown
above. Focus the image by turning the knobs below
the focuser.
Downloading and
Activating the App
Before you take your telescope outside, download
the StarSense Explorer app to your mobile device.
Search for “Celestron StarSense 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.
