CAUTION! Never look directly at the Sun – even for an instant – through your telescope or finderscope without a
professionally made solar filter 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 finderscope
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.
Be sure to check the box carefully, as some parts are small. All screws should be tightened securely to
eliminate flexing 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 fingers. 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 (except for Blitz 70s BASE) (fig. 2).
• 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 (except for Blitz 70s BASE).
• Place the accessory tray on top of the bracket, and secure it with thumbscrews from underneath or
secure the accessory tray with one screw in the middle of the tray (except for Blitz 50 BASE, Blitz 70s
BASE).
Mount assembly
Mount without a fork (fig. 3a):
• The telescope tube has a mounting tab on its underside. Place this tab into the slot on the tripod top.
• Tighten the knurled knob on the tripod head to attach the tube onto the tripod.
• Screw the altitude slow-motion control into the threaded socket at the rear of the mount.
Fork mount (fig. 3b):
• 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.
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-defined ordering.
Refractors (fig. 1a, 1b): Loosen the focuser thumbscrew. Insert the diagonal mirror into the focuser tube
and retighten the thumbscrew to hold the diagonal mirror in place (fig. 5a). 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 focuser and the eyepiece.
Reflectors (fig. 1c): Loosen the focuser thumbscrew and take off the plastic cap from the focuser tube.
Insert the selected eyepiece and secure it by retightening the thumbscrew (fig. 5b). If a Barlow lens is
needed, install it between the focuser and the eyepiece.
Barlow lens
A Barlow lens increases the magnifying power of an eyepiece, while reducing the field 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 magnification, the benefits 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 magnification. And the best advantage is that a Barlow
lens can potentially double the number of eyepieces in your collection.
