10. In order for you to get the optimum performance from the mount and OTA combination you must assemble and adjust the mount correctly The following fundamentals of telescope mounts are included to help you understand the big picture before you get into the specific details of the ZEQ25 mount Telescope mounts are either equatorial mounts or altitude azimuth Alt Az mounts Both types of mounts rotate the OTA around two perpendicular axes to point to a desired object in the night sky An equatorial mount has the right ascension R A axis aligned with the celestial North Pole CNP or celestial South Pole CSP in southern hemisphere to provide rotation matching the celestial sphere rotation around the Earth and the declination axis DEC to provide elevation relative to the celestial equator Since all celestial objects appear to rotate around the CNP the R A axis allows the OTA to rotate with the celestial sphere and provide accurate tracking for visual observations and astrophotography R A is the celestial equivalent of longitude Like longitude R A measures an angle that increases toward the East as measured from a zero reference point on the celestial equator An Alt Az mount has a horizontal axis to provide vertical altitude OTA movement from the local horizon and a vertical axis to provide horizontal azimuth OTA movement similar to compass headings An Alt Az mount can provide tracking that is good enough for visual observing and short
