What the NexStar 4 SE is and who it is for

The Celestron NexStar 4 SE is a 102mm Maksutov-Cassegrain computerized telescope designed for visual astronomy. Its 4-inch aperture gathers ample light for detailed planetary and deep-sky observation. The single fork arm mount includes a GoTo system with a database of 38,181 objects. A 25mm eyepiece and StarPointer finderscope are included in the box.

What this replaces and when the jump is worth it

The package adds a SkyPortal WiFi module for wireless control via mobile device, replacing the need for a wired hand controller during alignment and slewing. Upgrading from a manual alt-azimuth or equatorial mount is worth it when you want automated object location without learning star-hopping. The flash-upgradeable hand control keeps firmware current.

Who this suits and who should look elsewhere

The telescope suits beginners and experienced observers who want a portable, computerized system with a compact optical tube. SkyAlign software enables quick setup by aligning on any three bright celestial objects. Buyers who want a larger aperture for fainter deep-sky objects should consider other models. The 1.25-inch eyepiece barrel limits the maximum true field of view.
