203.2 mm EdgeHD optics with automatic alignment
Celestron NexStar Evolution 8 HD combines flat-field optics and StarSense AutoAlign with a rechargeable, WiFi-enabled mount for visual astronomy.
203.2 mmaperture
Corrected EdgeHD optics
The EdgeHD design reduces off-axis coma and field curvature, helping stars stay better corrected across the view.
2032 mmfocal length
Two starting magnifications
The included 40 mm and 13 mm eyepieces give approximately 51x and 156x. Start at lower power to find and frame a target.
GoTomotorised pointing
Align, then select a target
StarSense AutoAlign reads the star field to align the mount. After alignment, the motors locate and track selected objects.
Manual clutches and carry handles
The single-fork Evolution mount combines motorised pointing with manual movement in altitude and azimuth. Carry handles and accessory trays make the observing setup easier to manage.
Worm gears drive both axes, while the altitude and azimuth clutches allow manual positioning for setup and storage.
StarSense alignment, then wireless GoTo
02
Calibrate and align
Follow the first-use alignment and camera-calibration procedure. Once calibrated, StarSense can automatically align at the start of later sessions. StarSense calibration instructions.
03
Select an object
Choose a target after alignment and let GoTo move the telescope. Tracking keeps the view centred as the Earth rotates. Evolution setup manual.
Rechargeable power built into the mount
Up to 10 hoursRated observing runtime from the integrated battery. Actual endurance varies with use.
LiFePO4 batteryRechargeable lithium iron phosphate chemistry. Use the supplied AC adapter to charge the telescope.
USB chargingThe mount’s USB output can top up a smart device during an observing session.
Fully charge before the first session. During storage, recharge every 3 to 6 months rather than leaving the battery flat.
Plan the imaging accessories and connections
Visual and short-exposure use
The supplied alt-azimuth mount tracks objects for eyepiece observing. Lunar and planetary imaging uses an additional camera and suitable adapters.
Long-exposure deep-sky imaging
Alt-azimuth tracking still allows the field to rotate during long exposures. The optional Celestron 93665 wedge lists Evolution 8HD compatibility. It fits between mount and tripod; polar alignment is required for equatorial tracking.
Four AUX ports
The hand control can use any AUX port. There is no built-in GPS, autoguide port or periodic error correction.
Optional faster optics
The EdgeHD tube is Fastar/HyperStar compatible. Imaging at f/2 requires a compatible optional HyperStar lens and camera. The model-specific optional EdgeHD reducer gives f/7.

Good to know
Allow for the complete setup
The assembled kit weighs approximately 19.1 kg. Plan transport and assembly around the tube, mount and tripod.
Manual movement resets alignment
Release the clutches for setup or storage. If you move an aligned telescope manually, repeat alignment before using GoTo.
Solar observing requires specialist protection
Never look at the Sun without a suitable, securely fitted front aperture solar filter. Never project the Sun or use an eyepiece solar filter or Herschel wedge. Permanent eye injury can result. Supervise children.
