Celestron NexStar Evolution 9.25 HD Telescope
Corrected 235 mm optics. StarSense handles the alignment.
A premium EdgeHD system for detailed visual observing and a practical path into lunar, planetary and brighter deep-sky imaging.
235 mm
EdgeHD aperture
Up to 10
additional alignment stars
10 hours
integrated battery runtime
28.4 kg
complete kit weight
EdgeHD optical correction
A flatter field from centre to edge.
The aplanatic EdgeHD design reduces off-axis coma and field curvature. Celestron states that its focal plane is more than three times flatter than a standard Schmidt-Cassegrain design, helping stars remain better corrected across full-frame sensors. StarBright XLT coatings support bright visual views.
Step 02
Let StarSense read the sky.
StarSense scans star patterns and calculates the telescope's location, date and time. Up to 10 additional alignment stars can be added.
Step 03
Select the first target.
After alignment, choose an object in the app and command the Evolution mount to slew to it.
The complete Evolution mount system
Power, tracking, connections and software work together.
The optical tube is only half the system. The mount is built to keep a long observing session moving from alignment to target selection and tracking.
Integrated power
Up to 10 hours without a separate field battery.
The built-in lithium iron phosphate battery is rated for a full extended observing session.
Drive system
Brass worm gears, DC servo motors and manual clutches.
Nine slew speeds reach up to 4 degrees per second, with sidereal, solar and lunar tracking rates.
Connections
Four AUX ports plus USB paths.
The hand control can use any AUX port. USB is available through the hand control input and mount output.
Included software
SkyPortal, Starry Night and Celestron PWI.
Plan sessions, control the telescope and build more advanced pointing models through the supplied software ecosystem.
Visual observing and beginning astroimaging
Three supported ways to use the 235 mm EdgeHD system.
Detailed visual observing
Use the supplied 25 mm eyepiece for 94x magnification, then add compatible eyepieces as your observing develops.
Moon and planets
Attach a planetary imaging camera for short-exposure lunar and planetary capture.
Brighter deep-sky targets
Experiment with a DSLR on brighter objects. Add an equatorial wedge when longer exposures become the goal.
What the imaging system supports, and what it still needs.
Optional f/2 path
Fastar/HyperStar compatible. Requires an optional compatible third-party lens assembly.
Longer exposures
Add an Evolution equatorial wedge. EQ North and EQ South alignment require a wedge.
Accessory control
Four AUX ports and USB connections. The hand control can use any AUX port.
Not built in
No GPS, autoguide port or periodic error correction. Plan the broader imaging system around these limits.
Who this 28.4 kg EdgeHD system suits.
A good fit if
- You want 235 mm EdgeHD optics for detailed visual observing.
- You value automatic alignment and phone or tablet control.
- You want to begin with lunar, planetary and brighter deep-sky imaging.
Another setup may suit you if
- You need a much lighter complete kit than 28.4 kg.
- You require a built-in autoguide port or periodic error correction.
- You want equatorial long-exposure imaging without adding a wedge.

The complete kit weighs 28.4 kg.
The optical tube weighs 9.53 kg, the mount head 7 kg and the tripod 12.06 kg. Plan transport and assembly around the separated components.
Equatorial imaging requires a wedge.
The supplied mount is an altitude-azimuth single-fork system. EQ North and EQ South alignment are available only with an equatorial wedge.
Solar observing needs a proper solar filter.
Never look at or project the Sun without the correct solar filter. Permanent eye injury and heat damage can result. Do not leave the telescope unsupervised around children.
