This is a comprehensive review of the Celestron NexStar 8SE telescope, showing you the good and the bad. Celestron NexStar 8SE (Click for Latest Price)If you’re serious about parting with a significant chunk of cash, for what is a great telescope, then read on.At Love the Night Sky, we believe the Celestron NexStar 8SE is a great beginner's telescope, but...We also believe you shouldn’t be surprised by what you've bought after reading one of our reviews.Like all the great things in life, the 8SE is not perfect (sadly).Read on to discover its small imperfections (and how to beat them), find out how to get the most value out of it and discover what current owners have to say about the 8SE and why they think it was well worth the money spent!The Celestron NexStar Range of TelescopesThe Celestron NexStar telescope range is a series of catadioptric telescopes in four sizes. Catadioptrics combine mirrors and lenses to provide a long focal length in a relatively short body. (You can read more here)In the range, there are 4”, 5”, 6” and 8” models.Each model comes with an altazimuth mount. Also included are motorized go-to tracking with easy 3-star alignment (we'll look at that in more detail later) and a database of 40,000 objects.At 8 inches of aperture, the NexStar 8SE is the ‘daddy’ of the group. It's a great choice if you’re an astronomy beginner or upgrader who:Has a decent budget (plan on spending $1200 - $1600, depending on accessories)A thirst for big light-gathering powerWants to see the best objects in the night sky within an hour of getting your scopeThe 8" NexStar is more popular than both the 4” and 5” models, and collects 77% more light that the 6" model. In this review, we’ll break down why it such a desirable scope and, more importantly, whether it’s the right one for you.The rest of this review covers these sections:The NexStar 8SE’s SpecsThe 8SE Telescope and its opticsCelestron's altazimuth mount for the 8SEThe goto motor and space object databaseWhat NexStar 8SE owners say about their scopeNexStar owner's resourcesOur recommendations for the Celestron NexStar 8SE Quick NavigationThe Celestron NexStar Range of Telescopes Specifications of The Celestron NexStar 8SEThe 8SE Telescope and OpticsThe NexStar's Altzimuth MountThe Goto Motor and Space Object DatabaseWhat NexStar 8SE Owners SayHelpful NexStar Owner's ResourcesOur Recommendation for the NexStar 8SE TelescopeRecommended Extras for the NexStar 8SETo go straight to the section you’re interested in, use the 'Quick Navigation' box on the right.

CLICK HERE TO VIEW CURRENT PRICING The 8SE Telescope and OpticsAn 8” primary mirror is a thing of beauty.With that aperture, you’ll be able to see objects down to magnitude 14, which just brings Pluto within reach if you have dark enough skies.The optics in the NexStar 8SE are incredibly well made and provide brilliant image clarity and detail.It’s aperture and focal length, mean the 8SE gives great viewing at the 150x to 200x magnification levels. This is ideal for the moon and planets, and you can push it beyond 200x for bright objects in good seeing.Of course, it's big aperture will show dimmer objects like galaxies and nebulae in detail. Even if you've had a 6" scope before, this one, with its extra 2" of aperture, gathers 77% more light- which makes a big difference to what you can see.What You Can See with the NexStar 8SE TelescopeAt a dark site you should be able to see the following objects with this 8” aperture telescope:Cloud bands on JupiterJupiter's moons (and their shadows) transiting the planetNeptune and her moon TritonSaturn's surface bands and Cassini Division in her ringsMany of Saturn's moons Martian ice caps and little moons Phobos and DeimosMany, many galaxies and nebulae, including all the Messier catalogueOne owner says that 'even colors begin to make themselves apparent [in the nebulae]'This article gives you much more detail about what you should expect to see with 8" of aperture, compared to just 6 inches. For example, looking at the second-last row, you'll see that a telescope of NexStar 8SE’s size will do a much better job of resolving double stars separated by less than an arcsecond.A similar discussion about what the 8SE can see was had in the Stargazers Lounge forum, and you can read the conversation here.Build quality is robust on the NexStar 8SE. That doesn’t mean it can be abused without consequence. But, it should suffer the odd knock in the field without you paying a heavy price for it. Collimating a NexStar telescope with Bob's Knobs (source)Whether you knock it or not, all telescopes which use mirrors come out of alignment eventually. When that happens on your 8SE, you'll have to collimate it. Here's a great 'how-to' guide on collimating the NexStar 8SE.Collimation requires a screwdriver to adjust the three screws which hold the mirror (see the picture).To make the process easier and less risky, replace the screws with a set of ‘Bob’s Knobs’. With these in place, collimation becomes a less risky job you can do with just your fingers. Celestron NexStar 8SE on altazimuth mount (click for latest price)Setting Up the NexStar 8SEWhen you see a picture of Celestron’s 8-incher, you might not appreciate just how easy it is to set up and transport.As with any telescope, if you read the instruction manual thoroughly first, setting it up will be easier and faster. Even so, if you've never used a scope before, allow yourself at least an hour to get going.With repeated use, you will get quicker at setting up and taking down the 8SE. Many owners report that once you’ve gone through the process a few times to get used to it, setup takes as little as fifteen minutes.Takedown is just as quick and the whole scope packs away into rather small dimensions - certainly small enough for the average trunk.Which brings us to the question of storage. NexStar Carrying Case (click for latest price)Your 8SE will arrive in boxes that are robust and adequate for storage and transporting, to begin with. Over time and use, they will get tired.When they stop being useful, consider the storage/carrying case designed for the NexStar range.This will make it easier to carry and provides your precious telescope with great protection during storage and transportation.There's one final thing to think about when setting up your 8SE...Temperature!Like all catadioptric scopes, the tube is a sealed unit, so takes a long time for the air trapped inside to equalize its temperature with the outside world.When there's a difference in temperature between the scope and the air outside, you don't get great performance.For best viewing, get the scope set up outside 2-3 hours before using it. If the night is cold, use a dew shield to prevent the scope misting up with condensation. Verdict: A great ‘light bucket’ of a telescope which is quick and simple to erect. Although it's not the lightest of scopes, the 8SE is sturdy and compact enough to transport with ease, especially using the purpose-designed NexStar case. CLICK HERE TO VIEW CURRENT PRICING The NexStar's Altzimuth MountAn altazimuth mount is one which can be simply moved up/down and left/right. This means you can point your scope at any part of the sky.Unlike an equatorial mount, altazimuth mounts are not aligned to Earth's angle of rotation.Why is that important, you might ask, well… unless you’re thinking about astrophotography, it’s not important at all.The NexStar 8SE and AstrophotographyThe 8SE comes with a computerised tracking motor and it will keep objects in your eyepiece as they slowly move across the night sky. For naked eye viewing, that's great. Orion Nebula through the NexStar 8SE telescope (source)However, if you do want to get into astrophotography, then the tracking motor coupled to an alt-az mount has limitations. In particular, there is some ‘drift’ of the scope over time. This means images with long exposure times will have trails on them.Bright objects, such as the moon and planets, only need short exposures, so you can still produce great astropics of them with the 8SE.But...If deep space galaxies and faint nebulae are your things, then that's more of a challenge, although this guy seems to be doing just fine, judging from his pictures.You can mount the 8SE on an equatorial mount and the Celestron C90 T-adapter and T-mount let you attach your DSLR camera to the 8SE.Best Ways to Mount the 8SEThe major benefit of an altazimuth mount is you don't need to worry about polar alignment. Your scope is ready to go as soon as it's mounted.When setting up the Celestron NexStar 8SE though, actually attaching the telescope to the mount is the most difficult part of setup.Advice from owners is to attach the scope to the single-armed fork first (and on a soft surface like carpet to prevent scratches). Then, make sure it’s securely locked in place before finally attaching the fork to the stand.You’re much less likely to damage the scope accidentally doing it this way. Because you won't be using the locking screws whilst holding a heavy telescope above waist height, there's less chance you'll slip and damage the scope.One other piece of advice is to mount the telescope as far forward in its mounting housing as you can safely get it. This prevents the eyepiece hitting the mount when you point the scope towards the zenith.The 8SE Single Arm Fork and Vibration IssuesFor the NexStar models, Celestron has chosen to mount them on a single-armed fork.That single arm has to support a lot of weight in the 8SE. Without a steadying second arm, you will see some minor vibration at the eyepiece when you touch the scope, such as when adjusting focus.Thankfully, 8SE owners have come up with three ways you can manage this annoyance. From the cheapest to most expensive, they are:Pause in between each turn of the focussing wheel to let any vibration subside (free)Get vibration dampening pads for the mount which will effectively remove most of the tremor (about $50)Install a motorised focuser so you don't need to touch the telescope by hand (about $80)Verdict: Vibration through the mount is the weakest link of this otherwise amazing telescope package, although it is easily remedied. Setup of the NexStar 8SE is simple and straightforward, even a complete beginner can be looking at stars through the eyepiece within an hour. CLICK HERE TO VIEW CURRENT PRICING The Goto Motor and Space Object DatabaseSo, you’ve got your wonderful NexStar 8SE mounted and ready to go.It’s time to complete setup by telling it where in the world you are so you can find objects to look at with ease.The database and goto motor take away all the heartache of trying to locate an object by map reading and star-hopping. Instead, with these clever electronics, you'll go straight to the object you want to see and use your precious viewing time studying it rather than trying to find it!How to Use Celestron's SkyAlign TechnologyA galaxy and nebula takes up such a small piece of sky that your telescope needs incredibly accurate aiming to get it centred in your eyepiece and then track it as Earth rotates.To be as accurate as possible, Celestron’s goto system needs to know exactly where on the planet your telescope is and the precise local time.Celestron's NexStar range has technology they call ‘SkyAlign’ to achieve this. For SkyAlign to work at its best, you need to do three things:Your exact locationThe local time (including time zone and daylight savings info)Show it the location of three bright, night sky objectsBefore doing any of that, you must make sure the telescope is level (it comes with a spirit level) and the viewfinder is aligned with the scope (otherwise you won't be able to point it at the three bright objects when the time comes).The easiest time to align the red dot viewfinder is during the day. Point the telescope at a distant, stationary object like a telegraph pole, chimney or radio mast. Centre the top of the object in your eyepiece.Now, without moving the main scope, adjust the viewfinder so that the same object’s top is in the very centre of the viewfinder. When it is, your scope and viewfinder are aligned!At night, when you’re ready to use the scope, enter your location. You can use the nearest town, but you’ll have a better experience if you put in the coordinates of where you’re actually observing from.Put the local time in the go-to controller. You also need to give your timezone and say whether daylight savings is in force or not.With that done, it’s time to do the three star align.Find three bright stars in your sky. It's best if they're in different parts of the sky and there are no points of light nearby which could confuse the sensor, such as street lights.Celestron’s video shows you exactly what to do. That's it, you can now start observing!Pick a star, planet or deep space object from the database and get looking.Our advice is to do some daytime preparation for an evening's viewing. Make sure you know what's visible at the time and location you’ll be using the scope. That way, you won’t waste time trying to see stuff that’s not out.Powering the Goto 8SE MotorThe biggest bugbear amongst users of the NexStar telescope range is...Power supply!The goto controller is ‘powered’ by AA batteries.However, you cannot use rechargeables as they don't have enough ‘juice’, and even a decent branded set of AAs will get quickly eaten by your setup.The reality is, they are really only there to retain information like date and time when the unit is switched off.However, despite many, many complaints across the internet, Celestron does not package the NexStar range with any power cable. You will need to get at least one of the following for any serious usage of the equipment (affiliate links):Power packAC adapterIf you buy the adapter, make sure you get at least six foot of cord so you won’t pull it out moving the telescope around.Your first night as an 8SE owner will be so much more rewarding if you've got your power source sorted!Controlling the Goto 8SE MotorThe NexStar database has 40,000 objects stored within it. You select from planets, stars and deep space objects using the controller. Make your choice and the telescope will quickly slew to point at it.As you get more into astronomy, you may want to use other software for controlling your 8SE. So, you’ll be pleased to learn that you can do exactly that.The free (and brilliant) software Stellarium can be used control your goto motor, just see the video for how.You can also use your iPhone or iPad to control where your telescope is pointing by using the SkyQ Link (affiliate link).Essentially a WiFi adapter, the SkyQ Link picks up control signals from your iDevice using the relevant app. Verdict: The NexStar 8SE's goto and tracking motor is a very intelligent piece of programming. By simply telling it where you are, your telescope will find up to 40,000 different objects for you to look at... and you can just enjoy seeing them, rather than wasting time trying to find them.
