Celestron’s iconic “orange tube” design is updated with the latest technology to deliver an exceptional stargazing experience for beginners and experienced observers alike. The NexStar 4SE combines advanced features, excellent optics, and an easy-to-use system in one compact package — making it an ideal first serious telescope at an economical price.

4-Inch Aperture with Impressive Light-Gathering Power

The 4-inch aperture provides excellent light-gathering ability at an affordable price, all while retaining a compact form factor.

With the NexStar 4SE, you can enjoy impressive views of:

• The Moon’s surface features

• Saturn’s rings

• Jupiter’s cloud bands

• Deep-sky objects like the Orion Nebula

Take the 4SE to a dark-sky site and you’ll also see:

• Hundreds of pinpoint stars in the Hercules Globular Cluster

• The spiral arms of the Whirlpool Galaxy

Fully Automated GoTo Mount with 40,000+ Object Database

The NexStar 4SE features a fully automated GoTo mount with a database of more than 40,000 celestial objects. The system automatically locates and tracks objects for you, making observing simple and intuitive.

Using the included NexStar+ hand control, you can:

• Locate over 40,000 celestial objects

• Take a Sky Tour and let the telescope show you the best objects currently visible

• Track your favourite targets with push-button ease

High-quality components and sturdy construction provide the pointing and tracking accuracy needed for reliable performance.

SkyAlign Technology for Fast, Easy Setup

Thanks to SkyAlign technology, alignment is quick and painless — even if you’re unfamiliar with the night sky.

Alignment is as easy as 1-2-3:

1. Center three bright objects in your eyepiece

2. Press ALIGN

3. Begin observing

For even easier alignment, you can attach StarSense AutoAlign and your NexStar SE aligns itself.

Revolutionary Single Fork Arm Mount

Celestron’s engineers designed the NexStar SE’s unique, patented single fork arm mount for maximum portability and quick setup.

• Breaks down into lightweight, compact components

• Easy to transport, even in small vehicles

• Quick assembly in your backyard or at your favourite observing site

• Sturdy steel tripod for stable support

The design ensures the telescope is one you’ll use often — portable, practical, and simple to set up.

A Legacy Reimagined for the 21st Century

In the 1970s, Celestron’s Schmidt-Cassegrain telescopes helped bring astronomy to the masses. Founder Tom Johnson developed Celestron’s proprietary method of producing Schmidt corrector plates, delivering superior views with maximum portability.

His vision was to create high-quality optical instruments at an affordable price — inspiring generations of amateur astronomers. Four decades later, the NexStar SE builds upon that legacy with cutting-edge features while staying true to that original intent.

Advanced Features That Grow with You

The NexStar SE is compatible with a range of high-tech accessories for expanding your observing capabilities.

• Add GPS functionality with SkySync

• Add automatic alignment with StarSense AutoAlign

• Use the built-in wedge to track long exposures

• Pair with NexImage cameras for imaging the Moon and planets

From your first observing session and for years to come, the NexStar 4SE is designed to be a trusted companion in exploring the night sky.

Solar Warning

Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.

Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.

Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
