EyEpiEcEs
The accessory kit comes two eyepieces for medium to higher power viewing. The 17 mm eyepiece will give a medium power
but wider a field of view, while the 6 mm is higher power but gives a narrow field of view. Consult your telescope’s owner’s
manual for information on calculating magnification and field of view.
Barlow / T-adapTEr
The Barlow / T-adapter can be used in three ways:
1. Visual Barlow: Use this to double the magnification of any eyepiece used in your telescope. To do this, install the Barlow
lens between the eyepiece and the eyepiece holder of your telescope.
2. T-adapter: Use this to attach a dSlR camera to your telescope for basic imaging. If you have a 1000 mm focal length
telescope, the telescope will function as a 1000 mm telephoto lens. To do this, remove the black lens assembly from the
bottom of the Barlow by unthreading it from the silver barrel. Insert the silver barrel into your telescope’s eyepiece holder
and secure it well using the set screws. Thread a T-ring (sold separately) onto the large threads at the back of the Barlow.
Now attach your dSlR camera to the T-ring. To focus the camera, use the telescope’s focus knob while looking through
the viewfinder or by using “live preview” mode (if supported). Some short focal length telescopes or telescopes with limited
inward focus travel may not reach focus with this method, but should still be able to work using the next method.
3. Teleconverter: Use this to attach a dSlR camera to your telescope while doubling the focal length of the scope. If you have
a telescope with a 1000 mm focal length, using this method will double the power of the telescope making it equivalent to
a 2000 mm telephoto lens. To do this, insert the silver barrel into your telescope’s eyepiece holder and secure it well using
the set screws. Thread a T-ring (sold separately) onto the large threads at the back of the Barlow. Now attach your dSlR
camera to the T-ring. To focus the camera, use the telescope’s focus knob while looking through the viewfinder or by using
“live preview” mode if your camera supports this.
Note: To connect your camera, you will need a DLSR with a removable lens assembly. T-rings are available through your local camera stores and must be purchased for the exact brand and
model of camera that you own. The T-Ring attach to the body of the camera in place of the normal lens, allowing you to thread it securely to your T-adapter.
