Levenhuk Skyline AZ Telescopes

Congratulations on your purchase of a high-quality Levenhuk telescope! These instructions will help you set up, properly use, and care for your telescope. Please read them thoroughly before getting started.

CAUTION! Never look directly at the Sun – even for an instant – through your telescope or nderscope without a professionally made solar lter that completely covers the front of the instrument, or permanent eye damage may result. To avoid damage to the internal parts of your telescope, make sure the front end of the nderscope is covered with aluminum foil or another non-transparent material. Children should use the telescope under adult supervision only.

All parts of the telescope will arrive in one box. Be careful when unpacking it. We recommend keeping the original shipping containers. In the event that the telescope needs to be shipped to another location, having the proper shipping containers will help ensure that your telescope survives the journey intact. Make sure all the parts are present in the packaging. Be sure to check the box carefully, as some parts are small. No tools are needed other than those provided. All screws should be tightened securely to eliminate exing and wobbling, but be careful not to overtighten them, as that may strip the threads. During assembly (and anytime, for that matter), do not touch the surfaces of the optical elements with your ngers. The optical surfaces have delicate coatings on them that can easily be damaged if touched. Never remove lenses or mirrors from their housing, or the product warranty will be null and void.

Tripod assembly

• Slowly loosen the tripod locking knobs and gently pull out the lower section of each tripod leg. Tighten the screws to hold the legs in place.

• Spread the tripod legs apart to stand the tripod upright.

• Adjust the height of each tripod leg until the tripod head is properly leveled. Note that the tripod legs may not be the same length when the mount is leveled.

• Place the accessory tray on top of the bracket, and secure it with thumbscrews from underneath.

For Levenhuk Skyline 50x600 AZ, 60x700 AZ: secure the accessory tray with one screw in the middle of the tray. 1a,

Telescope assembly (models with fork mount)

• Remove the locking screw from the slow-motion control rod.

• Insert the rod into the hole on the side of the fork mount.

• Place the telescope tube between fork arms so that holes on the tube match the arm holes. Fasten the telescope tube to the mount with thumbscrews.

• Fasten the other end of the rod to the telescope tube by inserting the screw through shaft and tube holes and tightening it.

Telescope assembly (50x600 AZ):

• Remove the altitude lock knob from the mount head.

• Place the telescope optical tube on the altazimuth mount so that the hole in the optical tube lines up with the hole in the mount head.

• Insert the altitude lock knob through the mount head and optical tube. Make sure the hole is clear all the way through before tightening the knob. Secure the altitude lock knob. 2a

Diagonal mirror and eyepiece assembly

Refractors: 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.

Reectors: Loosen the focuser thumbscrew. Take off the plastic cap from the eyepiece tube. Insert the selected eyepiece and secure it by retightening the thumbscrew.

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 4a, reector 4b)

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.

To align the nderscope, choose a distant object that is at least 300 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.

Operating the mount

The AZ, AZ1, AZ2 mounts are alt-azimuth mounts that allow you to rotate the telescope about the

vertical and horizontal axes and vary 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.

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.

Barlow lens

A Barlow lens increases the magnifying power of an eyepiece, while reducing the eld of view. It expands the cone of the focused light before it reaches the focal point, so that the telescope’s focal length appears longer to the eyepiece. In addition to increasing magnication, the benets of using a Barlow lens include improved eye relief, and reduced spherical aberration of the eyepiece. For this reason, a Barlow plus a lens often outperform a single lens producing the same magnication. And the best advantage is that a Barlow lens can potentially double the number of eyepieces in your collection. (refractor , reector )

8a 8b

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 , reector )

9a 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.
