NexStar 6SE Computerized Telescope
Description
Celestron’s signature orange-tube telescope combines advanced features and excellent optics in one easy-to-use system, the NexStar 6SE. It’s the perfect choice for your first serious telescope, offering striking views at an economical price.
Our Founder’s Vision, Reimagined for the 21st Century
In the 1970s, Celestron’s Schmidt-Cassegrain telescopes brought the hobby of astronomy to the masses and established Celestron as the world’s premier telescope maker. Our founder, Tom Johnson, invented Celestron’s proprietary method of producing Schmidt corrector plates for superior views and maximum portability. Johnson believed in creating high-quality optical instruments at an affordable price, and inspired a generation of amateur astronomers.
Four decades later, we’ve improved upon this design by adding cutting-edge features, while staying true to our founder’s intent.
View the Universe’s Most Impressive Celestial Objects
The 6SE’s six-inch primary mirror packs enough light-gathering ability to observe the best that the solar system has to offer: Cassini’s Division in Saturn’s rings, the cloud bands on Jupiter, and geographic features on the surface of the Moon. When it comes to deep sky objects, take your 6SE to a dark-sky site and you’ll see hundreds of pinpoint stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy, and more.
Revolutionary Single Fork Arm Mount
We know the best telescope is the one you will use most often. That’s why Celestron’s engineers created NexStar SE’s unique, patented single fork arm mount. It’s perfectly portable and makes setup quick and easy. What’s more, the NexStar SE breaks down into several lightweight and compact pieces, making it easy to transport, even in small vehicles. You’ll have no problem getting the NexStar SE to your favorite observing site, or setting it up quickly in your backyard.
Of course, it’s what’s inside the mount that really counts. Sturdy construction from high-quality components give NexStar SE the pointing and tracking accuracy needed to observe and follow your favorite targets with push-button ease. Use the included NexStar+ hand control to locate over 40,000 celestial objects, or take a Sky Tour and let your telescope show you the best objects currently visible.
Aligning your telescope is simple and painless, too, thanks to SkyAlign. This process makes alignment as easy as 1-2-3: just center three bright objects in your eyepiece and press ALIGN. For even easier alignment, attach our StarSense AutoAlign and your NexStar SE aligns itself!
Advanced Features Let the NexStar SE Grow with You
The NexStar SE is compatible with all the high-tech accessories advanced users love. Provide GPS coordinates to your telescope with SkySync, or add automatic alignment functionality with StarSense AutoAlign.
For planetary imaging, pair your NexStar 6SE with one of our Skyris cameras. Or, experiment with wide-field deep sky astroimaging by replacing the telescope’s secondary mirror with a DSLR or astronomical CCD camera with a Fastar/HyperStar lens assembly. From your first observing session and for years to come, the NexStar SE is your trusted companion.
Celestron NexStar 6SE telescope: Full review
Combine the Celestron NexStar 6SE’s flawless optical coating, its ease of use and high-quality build and you have an instrument that is built to provide excellent views of the night sky for many observing sessions to come. Not many eyepieces are provided despite this Schmidt-Cassegrain’s high RRP and it does drain batteries quickly when in use, meaning that operation and add-ons come at an extra cost. A Vixen dovetail and a 1.25″ eyepiece fitting make this telescope versatile, affording the astronomer the opportunity to swap its mount and increase and improve their arsenal of filters and eyepieces, whilst being mindful of its useful magnification of 354x.
The Celestron NexStar 6SE is a telescope that’s an all-arounder, fit for a plethora of skywatching needs: especially since it can be used by beginners, who are just venturing into astronomy, and more seasoned observers with an excellent knowledge of the night sky (opens in new tab).
Celestron NexStar 6SE key specs Optical design: Schmidt-Cassegrain
Aperture: 150 mm (5.91″)
Focal length: 1499 mm (59″)
Focal ratio: f/10
Eyepiece focal length: 25 mm (60x)
Total kit weight: 21 lbs. (9.53 kg)
Mount type: Single-arm fork, alt-azimuth
Given its capabilities, this telescope is quite difficult to outgrow — it can be used as an observer’s main instrument or even as an add-on to existing kit, providing the astronomer with the flexibility of a quicker, fuss-free skywatching experience over more complex setups. The NexStar 6SE is easy to accessorize with additional eyepieces, red dot finders, filters and star diagonals, which is essential for bettering your views of solar system and deep-sky targets.
The telescope offers the opportunity to dabble in astrophotography, however, you will require a T-ring or adapter if you choose to image with a CCD, CMOS or DSLR or a smartphone adapter for photography with your iPhone or Android. Many beginners might find the idea of using a GoTo telescope daunting, but Celestron’s comprehensive manuals and software will put any worries to bed.
Celestron NexStar 6SE: Design
Sturdy, robust build
StarBright XLT optical coating for crisp views
Eight AA batteries drain quickly

A single 25mm Plössl eyepiece is supplied with the Celestron 6SE to provide a magnification of 60x, but so much more can be achieved from the optical system, so we advise purchasing a selection of eyepieces and filters — bearing in mind that the highest useful magnification is 354x — to get the very best out of this telescope.
Setting this Schmidt-Cassegrain up took next to no time at all, and we were impressed with the quality of many of its components, especially its red dot finder and sturdy stainless steel tripod. The robust build of the NexStar 6SE promises to last years of observing sessions, provided it is treated with care. Additionally, since catadioptric telescopes can succumb to moisture during observations, a dew shield would be a worthy investment to protect the optical system and prolong the telescope’s lifetime.
Weighing in at 21 lbs. (9.53 kilograms), the Celestron 6SE is a touch on the heavy side due to the technology and components compacted into it: a minor inconvenience for those who might need assistance in transporting their ‘scope from one location to another. Despite this, the NexStar 6SE boasts quality over lighter instruments, so we don’t consider this to be a major setback in the design.
What is quite a large flaw is the requirement of eight AA batteries to operate the computerized alt-azimuth fork mount. Sadly the NexStar 6SE drains batteries quite quickly, making using it quite frustrating when the computer “clocks out” whilst you’re engrossed in observing. Over time — and with constantly replacing the batteries — using the telescope has the potential to become quite an expensive enterprise.
Undeterred, we tried out rechargeable batteries (opens in new tab) as a means to investigate an alternative route for powering the NexStar 6SE, but discovered that the telescope would act strangely with low power and found a quick loss of charge was still a problem. We strongly recommend purchasing an AC power cord from Celestron — unfortunately, this is not included with the telescope.
Celestron promises a great deal when it comes to the operational abilities of this instrument, so we were delighted to discover that the NexStar 6SE did exactly what it says on the tin when we took it out to test on a clear December evening.
For one, the star alignment — which employs Celestron’s SkyAlign technology and enables calibration for accurately finding targets — was impressively simple, and it wasn’t long before we were all set up and ready to tour the winter night sky.
Celestron NexStar 6SE: First light and functionality
Noisy motorized mount and obvious vibration
Accurately tracks targets
No colour-fringing or visual defects
Our first target was the Orion Nebula (Messier 42) (opens in new tab), which can be found just below Orion’s Belt (opens in new tab) and is easily visible to the naked eye as a fuzzy patch, glowing at magnitude (opens in new tab) +4. Using the control to instruct the NexStar to view this diffuse nebula, the computerized mount ran smoothly and the GoTo technology was very accurate in locating objects. The Trapezium Cluster, for instance, is nestled at the heart of the Orion Nebula and was found to be aligned close to the centre of the field of view.
When we brought the heart of the star-forming region into view we did notice a degree of vibration while focusing but, once finished, observations could be taken in without any hindrance. Thanks to the excellent StarBright XLT optical coating our observations of the nebula and its stellar members were very crisp, bright and clear, with no defects in the optics.
While the telescope slews to its target — this model possesses nine speeds — the mount does make a great deal of noise, particularly when we used the moderate to fast settings. If you find the noise off-putting and are happy to observe without a computerized mount, it’s quite easy to switch over to a manual one given that the tube possesses a Vixen-style dovetail. Remember though, you will need a Vixen adapter if you want to fit the tube to another Celestron mount.
Heading back inside to warm up with a hot drink, we decided to give the NexStar’s lunar, solar and sidereal tracking a test and left it focused on a star. Upon returning to the telescope 30 minutes later, we found that our target hadn’t drifted out of the field of view, highlighting the instrument’s suitability for long-exposure astrophotography.

With the nearly-full moon taking pride of place quite late into the evening, we took the opportunity to view our natural satellite’s cratered surface. The lunar views that we saw were impressive: the NexStar revealed well-defined crater walls and lunar mare to a very high standard — the craters Copernicus and Tycho were particularly impressive and crystal clear using the modest 5.91” aperture.
With gas giant Jupiter also at a good position in the sky and a few degrees away from the moon, the NexStar made short work of locating the planet and its four largest satellites: Io, Europa, Ganymede and Callisto. Jupiter was visible in the field of view as a bright disk, with Ganymede and Europa appearing as sharp points of white light flanking the giant’s left limb, while Io and Callisto could be found relatively near to the planet’s right. Faint brown and cream bands were visible across Jupiter’s surface.
As we discovered when observing the Orion Nebula, views through the Schmidt-Cassegrain’s optics were impressively clear and bright with no chromatic aberration — or colour fringing — evident. Jupiter will only continue to make an excellent target by increasing the telescope’s magnification, something we highly recommend either by using a Barlow lens as well as additional eyepieces with a 1.25” fitting. A blue filter will provide excellent contrast, playing up the rills and festoons in the gas giant’s cloud layers and promote easy viewing of the planetary king’s famous storm: the Great Red Spot.
Celestron NexStar 6SE: Verdict
The NexStar 6SE is a great representation of Celestron’s iconic telescope range. Given its capabilities and revolutionary technology, the price tag is reasonable, but the package does lack a good selection of eyepieces that would provide an even greater variety of views. The setup offers a lifetime of observations provided it is treated with care and little-to-no maintenance is carried out on the optics and computerized mount.
The NexStar 6SE’s alignment technology takes the hassle out of calibrating the instrument and, once completed, the GoTo system is exceedingly accurate in locating targets at the touch of a button. The telescope’s database boasts 40,000 targets to slew to but, despite the useful magnification of 354x, it’s not possible to view all objects with clarity even with extra accessories, such as eyepieces and a Barlow Lens. In some cases though, astrophotography picks out some of the fainter targets that are visible in telescopes with larger apertures.
The GoTo facility does drain batteries and is a tad on the noisy side when in operation, but a constant power supply and taking the telescope to a remote location (if you’re concerned about waking the neighbors!) are easy fixes to an otherwise superb instrument.
Celestron – NexStar 6SE Schmidt-Cassegrain Computerized Telescope – 11068
Celestron NexStar 6SE Schmidt-Cassegrain Computerized Telescope
With an aperture of 150mm (6″), focal length of 1500mm and focal ratio of f/10, the Celestron NexStar 6SE Schmidt-Cassegrain Computerized Telescope is perfect for planetary observing. Since slower focal ratios render smaller field of views and high magnification, great detail can be resolved on objects with high surface brightness. The rings of Saturn and cloud bands of Jupiter should be easily apparent with this telescope. Even some deep sky objects might be within reach of this scope such as the Orion Nebula or bright globular clusters. Light reflectivity is also improved tremendously with Celestron’s StarBright XLT coatings with mirrors reaching a reflectivity rate of 95%, almost a 10% improvement over standard aluminum-based coatings.
The single arm fork mount keeps this telescope extremely portable, so it is perfect to take out for a night or two of hassle-free visual observing. Celestron has implemented a very simple alignment procedure so the observer can start viewing almost immediately. The SkyAlign method simply required the user to point and center three bright stars (or planets) after entering the date, time and location and the computer controller can calculate what stars were selected without the user even having to know the names. With the optional GPS SkySync Accessory (not included), the location and time entry is not necessary and the GPS will automatically gather that information from the first satellite available. To update the telescope’s operating system, the user can update via the internet through Flash Upgradeable Technology.

Celestron NexStar 6 SE 10 Telescope for sale online
Celestron spent lots of money on lenses, but way too little on ergonomics.
Doesn’t have an auto-off, so you burn $9.00 worth of batteries each time you forget to hit the off switch. The instruction manual does not match the product. There is a legal caveat acknowledging this, but the product is too complex and too expensive to have an incorrect and confusing instruction manual. It needs to be updated. The sighting device is a cheap red-dot scope from a kids Daisy air rifle, too cheap for a $700 telescope, and it doesn’t have sufficient adjustment range to get the dot aligned, so you just have to get it as close as possible and then extrapolate in your mind to where the telescope is really pointing. And there is no glare guard to the sighting device, so the smallest amount of ambient light creates a reflection of the sighting device base that prevents seeing stars through the sighting device. I find it bizzare that you must go through the alignment process each and every time you power up. The telescope would be infinitely more useful if you could align the telescope once, and not move it, and it would still be still aligned the next time. Yet the manufacture didn’t invest a dime to save the alignment. Particularly bad since you can’t leave the power on. Maybe an AC Adapter would fix that. I was originally very impressed by the alignment process-some really smart software engineers! After first successful alignment I said “find the moon” and it got real close, but the moon was just outside the view. With the cheapo viewfinder I didn’t know which way to nudge the moon back in view. (if you can’t find the moon, how will you ever find a distant star?) Then I said “find Uranus,” which worked. Then I said “find the moon” again, and the telescope pointed 180 deg away from the moon. I’m not so impressed anymore with the software. Read full review
