The power , or magnification of a telescope is determined by the focal length of the telescope and the focal length of the eyepiece being used.
T o calculate eyepiece power , divide the tele- scope's focal length by the eyepiece's focal length. It is important to understand that menu selections are set in a loop Fig.

Landmark Survey automatically slews the telescope to all user-defined landm Viewing terrestrial objects requires looking along the Earth's surface through heat waves. These heat waves often cause degradation of image quality. Low power eyepieces, like the MA 25mm eyepiece, magnify these heat waves less t Autostar provides a database of bright stars and two stars from this database are chosen by the observer for alignment.
Most satellites are in low orbit, tra veling at appro ximately 17, mph. They mov e quickly across the sky and are visible only f or a fe w minutes, requiring A utostar to slew the telescope r apidly. Best viewing is near Sunrise or Sunset when the sky is still dark.
In this format vignetting occurs: the photographic image appears on film with a slight darkening vignetting at the corners of the 35mm frame Fig. Meade accessories greatly extend many important applications to the telescope, from low-power , wide-field terrestrial viewing to high-power lunar and planetary observing. The premium quality of these accessories is well-suited to the quality of the The Set includes light yellow , very light red, very light blue, and neutral density filters.
