The Celestron NexStar 8SE is a Schmidt-Cassegrain telescope for visual observing of the Moon, planets and brighter deep-sky objects. Align the mount, choose a target and let its motors handle the pointing and tracking.
The 8-inch-class optical system gathers light for astronomical observing. Darker skies help reveal faint deep-sky targets; atmospheric steadiness controls the finest planetary detail.
The supplied 25 mm eyepiece gives approximately 81×. Changing to another compatible eyepiece changes the magnification; higher power is useful only when the target and conditions support it.
After alignment, select an object with the NexStar+ hand control. The single-arm mount moves to it and tracks its motion, reducing the need to keep nudging the telescope.
The 8SE puts its 8-inch optical tube on a single-arm mount with a removable hand control. A right-angle star diagonal lets you observe from beside the rear of the telescope. The tube, mount and tripod separate for transport.

Level the tripod, align the red-dot finder with the telescope and enter the location, date and time in the hand control.
Choose SkyAlign. Use the direction buttons to centre each object in the finder, then accurately in the eyepiece. You do not need to know the stars' names.
After alignment succeeds, select a target from the hand control. Sky Tour suggests objects for the current sky. A catalogue entry does not guarantee visibility from your site.
For the complete setup sequence, read the NexStar 8SE instruction manual.
AA batteries, external power supplies, cameras and WiFi modules are not included.
The mount takes eight AA batteries, which are not included. For an external supply, use a compatible centre-positive 12 V DC adapter or Celestron PowerTank. These are optional accessories.
In normal altazimuth use, field rotation limits long-exposure deep-sky imaging. Equatorial operation needs an optional wedge and accurate polar alignment.
Turbulent air softens detail at high power. Begin with the supplied eyepiece and increase magnification only while the view remains clear. Deep-sky objects are easier to see away from bright skies.
Never point the telescope or finder at the Sun without a properly fitted, suitable front-mounted solar filter. Never use an eyepiece solar filter or project the Sun. Permanent eye injury can result. Supervise children and never leave the telescope unattended.
