WARNING! Never use the Meade 16" Starfinder Telescope to look at the Sun! Observing the Sun, even for the shortest fraction of a second, will cause instant and irreversible damage to your eye as well as physical damage to the telescope itself. When observing with the telescope during the daytime, do not point the telescope even close to the Sun. 1 2 24 3 23 4 21 22 5 6 20 7 8 19 18 9 14 17 15 10 13 11 16 12

Most tracking errors are the result of improper balancing. With an improperly balanced telescope objects may become difficult to find or, once found, may be easily lost. To balance the telescope: 1. Loosen the declination lock kn

While the recommended supply voltage is 12vDC, the telescope will operate in a range of 6-18vDC. COLLIMATION OF THE OPTICAL SYSTEM After the secondary mirror assembly has been installed, it will be necessary to collimate, or align the secondary mirror with the primary mirror. 1.

Because of its much wider 2 field, the viewfinder may be of significant assistance in locating and centering objects, after the setting circles have been used to locate the approximate position of the object. Pinpoint application of the setting circles req

The Basic Camera Adapter (see OPTIONAL ACCESSORIES, this page) and T- Mount for your specific brand of SLR camera serve as the link between telescope and camera. The Starfinder Equatorial Telescope design allows the user to take short exposure photographs of the Moon and planets using either prime-focus or eyepiece projec
