WARNING:The accessory tray of the standard tripod ensures that the tripod legs are firmly expanded, which prevents the tripod from accidentally tipping over. When using the CQ40 on the standard tripod, an accessory tray should always be used to ensure stability. - Page 7 Fig.4 Right Ascension Clutch knob RA flexible control cable DEC lination Clutch knob DEC flexible control cable Latitude adjustment Latitude locking lever lever (up-down) M10 tripod clamping screw Slide the sleeve end of the RA and DEC flexible control cables over the nipples on the end of the worm gear axis.

INSTALLING THE TELESCOPE The clutch knobs on the right ascension and declination axis must be turned to a tight lock before mounting a tele- scope. Mount the telescope firmly onto the base using the telescope clamping knob (Fig.5 and ounting the telescope accessories Eyepiece Newton telescope type (fig.7): Focus tube... -

CQ40 mount The CQ40 mount is designed to be used in the Equatorial mode, which allows the user to take full advantage of the extra possibilities offered by this mode: - The CQ40’s setting circles can be used to help finding objects invisible to the naked eye. -

Vertical adjustment: This is the role of the latitude adjustment lever. Loosen the latitude locking lever, adjust the height till the marker of the latitude scale indicates the latitude of your observing site, and lock the latitude locking lever again. The adjustments described to reach EQ mode orientation of the mount, can be done with or without the telescope attached. - Page 11 Pointing to the North Celestial Celestial Pole Fig.15 Pole (NCP): For the following examples, it is as- sumed that the observing site is in the Northern Hemisphere. In the first case (Fig.15.2), the optical tube is pointing to the NCP. This is its probable position following the polar-alignment step.
- Page 12 Pointing to directions other than due North: Pointing in any direction other than due North requires a combination of R.A. and Dec positions (Fig.17). This can be visualized as a series of Dec arcs, each resulting from the position of rotation of the R.A. axis. In practice however, the telescope is usually pointed, with the aid of a finderscope, by loosening both the R.A.

sing the setting circles The quickest way to find objects is to learn the Constellations and use the Red Dot Finder for aiming. Downloading a star chart on a smartphone or tablet helps finding the position of faint objects which are not visible by the naked eye. -
Page 14: Choosing The Appropriate Eyepiece
hoosing the Appropriate Eyepiece Calculating the magnication (power) The magnification produced by a telescope is determined by the focal length of the eyepiece that is used with it. To determine a magnification for your telescope, divide its focal length by the focal length of the eyepieces you are going to use. -
Page 15: Observing The Sky
OBSERNING THE SKY ky conditions Sky conditions are usually defined by two atmospheric characteristics, seeing, or the steadiness of the air, and transparency, light scattering due to the amount of water vapour and particulate material in the air. When you ob- serve the Moon and the planets, and they appear as though water is running over them, you probably have bad “seeing”... - Page 16 CAUTION! NEVER USE YOUR TELESCOPE TO LOOK DIRECTLY AT THE SUN. PERMANENT EYE DAMAGE WILL RESULT. USE A PROPER SOLAR FILTER FIRMLY MOUNTED ON THE FRONT OF THE TELESCOPE FOR VIEWING THE SUN. WHEN OBSERVING THE SUN, PLACE A DUST CAP OVER YOUR FINDERSCOPE OR REMOVE IT TO PROTECT YOU FROM ACCIDENTAL EXPOSURE.
