Levenhuk Skyline BASE 110S [13/47] Camera adapter

Optical accessories assembly

Your telescope can be equipped with additional accessories, such as eyepieces, diagonal mirror or prism, or

a Barlow lens. The accessories should be installed in well-dened ordering.

Refractors (g. 4a): Loosen the focuser thumbscrew. Insert the diagonal mirror into the focuser tube and

retighten the thumbscrew to hold the diagonal mirror in place. Then, insert the desired eyepiece into the

diagonal mirror and secure it by retightening the thumbscrew. If a Barlow lens is needed, install it between

the diagonal mirror and the eyepiece.

Reectors (g. 4b): Loosen the focuser thumbscrew and take o the plastic cap from the focuser tube.

Insert the selected eyepiece and secure it by retightening the thumbscrew. If a Barlow lens is needed,

install it between the focuser and the eyepiece.

Optical nderscope assembly and alignment

Unthread two screws in the back of the telescope tube. Place the nderscope base above the holes on the

tube. Lock the nderscope base into position by tightening the screws (refractor 5a, reector 5b).

Optical nderscopes are very useful accessories. When they are correctly aligned with the telescope,

objects can be quickly located and brought to the center of the view. Turn the scope end in and out to

adjust focus (g. 6).

To align the nderscope, choose a distant object that is at least 550 yards (500 meters) away and point

the telescope at the object. Adjust the telescope so that the object is in the center of the view in

your eyepiece. Check the nderscope to see if the object is also centered on the crosshairs. Use three

adjustment screws to center the nderscope crosshairs on the object (g. 7).

Operating the mount

The AZ mount is an alt-azimuth mount that allows you to rotate the telescope about the vertical and

horizontal axes and change its altitude and azimuth. To adjust the azimuth, loosen the big locking knob

under the mount base and rotate the tube left or right about the axis then retighten it. To adjust the

altitude, loosen the altitude adjustment knob and rotate the tube. For more precise motions use the

altitude slow-motion control. Due to Earth’s movement, the objects will be constantly shifting out of your

view, so you will have to adjust the altitude and azimuth of your telescope to continue your observations

(g. 8).

Reference materials usually list declination coordinates in degrees, hours and minutes above or below the

horizon line. Azimuth coordinates may sometimes be listed with the compass points (N, SW, ENE, etc.), but

it is more commonly listed in degrees around the 360-deg plane, where north is 0°, east is 90°, etc.

Focusing

Slowly rotate the focus knobs one way or the other until the image in the eyepiece is sharp. The image

usually has to be nely refocused over time due to small variations caused by temperature changes,

exures, etc. Refocusing is almost always necessary when you change an eyepiece, add or remove a Barlow

lens (refractor 9a, reector 9b).

Camera adapter

To attach a camera to your telescope you may need an adapter to get the camera focused. Some refractors

are designed to be used with diagonal mirrors and thus need a longer focal length when used with camera.

To achieve that, simply attach an extender to the focuser of your telescope and then attach the camera

with a T-adapter to the extender (g. 10).
