Care and maintenance

• Never, under any circumstances, look directly at the Sun through this device without a special
filter, or look at another bright source of light or at a laser, as it may cause PERMANENT
RETINAL DAMAGE and may lead to BLINDNESS.
• Take the necessary precautions when using the device with children or others who have not read
or who do not fully understand these instructions.
• Do not try to disassemble the device on your own for any reason. For repairs and cleaning of any
kind, please contact your local specialized service center.
• Stop using the device if the lens fogs up. Do not wipe the lens! Remove moisture with a hair dryer
or point the telescope downward until the moisture naturally evaporates.
• Protect the device from sudden impact and excessive mechanical force.
• Do not touch the optical surfaces with your fingers. Clean the lens surface with compressed air
or a soft lens cleaning wipe. To clean the device exterior, use only the special cleaning wipes and
special tools that are recommended for cleaning the optics.
• Store the device in a dry, cool place away from hazardous acids and other chemicals, away from
heaters, open fire, and other sources of high temperatures.
• Replace the dust cap over the front end of the telescope whenever it is not in use. Always put
eyepieces in their protective cases and cover them with their caps. This prevents dust or dirt from
settling on the mirror or lens surfaces.
• Lubricate the mechanical components with metal and plastic connecting parts. Components to be
lubricated:
• Optical tube;
• Fine mechanics (focuser rail, telescope optical tube microfocuser);
• Mounting;
• Worm-and-worm pairs, bearings, cogs, threaded mounting gears.
Use all-purpose silicon-based greases with an operating temperature range of −60 ... +180°С
(−76 ... +356°F).
• If a part of the device or the battery is swallowed, seek medical attention immediately.
• Children should use the device under adult supervision only.
