11049 NexStar 4SE Computerised Maksutov-Cassegrain Telescope with Fully Automated Mount, SkyAlign Technology and XLT Coating, Black/Orange

This telescope is pretty good for the beginner who's not so interested in learning their way around the sky but is more inclined to be a tourist of the sky and who may intend to make use of the integrated equatorial wedge(otherwise the Nexstar 127 SLT is a better buy due to the extra inch of aperture). With 8 fresh quality AA batteries the GoTo is pretty accurate when setup properly (it uses American dating system), easily placing objects within the field of view of a 25, 32 or 40mm Plossl eyepiece. Downside is it eats through batteries as it only works at it's best with fresh batteries, if you observe a lot and for long periods a Celestron or Skywatcher 7ah or 17ah power tank is required. The focuser seems to work well with not much in the way of the vibration after focusing, the tripod is nice and stable when extended but don't go bumping into it. The accessory tray can easily hold 4 1.25" eyepieces and a Barlow Lens which I've found is all I need for observing with this scope. The optics are high quality producing good views of the moon, planets and double stars, and open clusters though these don't tend to fit in the whole view even when it's only had a short time to cool down. But if you're more interested in faint deep sky objects this telescope will have too small an aperture to satisfy you, and you'd be better off with the 8SE or a dobsonian. It is highly portable, I carry it from a living room through a hallway and two rooms in one piece fully assembled with tripod legs up and with eyepieces+barlow lens in their accessory tray, it'd be a good choice for someone living in a high flat. Last couple things is if you do get this scope or another of the SE series I highly reccomend purchasing the Celestron SkyQLink 1 or 2 either work with Android or iOS and using Skyportal app or Sky Safari 4 Plus or Pro to control the telescope, it's a lot better than using the handcontrol. You will also want a a Celestron or Skywatcher powertank to provide a steady power supply to keep the GoTo accurate for hours on end.

This is an excellent telescope. I've had a few telescopes in the past, but this one is much better. Really good quality and great size, but I recommend also buying the CELESTRON WIFI MODULE because I couldn't figure out why it wasn't connecting to my laptop, and then I realised I had to buy this additional product. They are about £130, so not cheap but definitely worth it as its not included with the telescope. Even if you don't want to do it online, you can align one planet in the sky, and it automatically knows where the others are. It works very well and is overall a great product. Building the stand/tripod might be a bit tricky, so I recommend watching a YouTube tutorial.

I study astrophysics at university and I wanted a scope so that I could do some amateur astrophotography in my spare time. The scope is very good value for money but you do pay a bit more. The scope can be set up by one person in under 5 minutes. It has brilliant features in the hand control that make it easy for beginners but incredibly flexible for more advanced users. The tripod is well built and very stable and has a wedge for photography and for setting the mount to equitorial. The finderscope is a brilliant addition. The scope itself has great optics and produces very clear images of stars and planets. I would recommend anyone get a few more eyepieces and a barlow lens to get more magnification. If you want to photograph deep sky objects alone (or fainter stars viewed in the eyepiece) I would suggest a scope with bigger aperture but definately from this range of telescope. Overall, the quality from the tripod, fork arm and scope are top notch. This would be an great choice for a starter scope, I am very pleased with it. Happy star-gazing.

FIRST IMPRESSIONS ON GETTING IT OUT OF ITS MANY BOXES. ON OF THEM SAID MADE IN CHINA WHOOPS IT NEARLY GOT RETURNED ASAP.BUT. i FIGURED CELESTRON HAD USED A RECLAIMED BOX THIS AINT CHINA ITS TOO GOOD SO DOWN TO THE NITTY GRITTY IT IS A SOLID MADE ITEM LOOKS AND FEELS GOOD. VERY EASY TO PUT TOGETHER i STUUFED SOME BATTERYS IN AND DID A MANUAL TERESTRIAL VIEWING OF A NEGHBOURS CHIMNEY. CLEAR AS CHRYSTAL. SO TONIGHT ITS JUPITER AND THE MOON i HAVE NOT AS YET SET UP THE GOTO BUT THE MOTORS SEEM TO BE SMOOTH AND THE TRIPOD IS SOLID AS A ROCK. SO SHOULD BE QUITE GOOD ENOUGH FOR LONG DISTANCE VIEWING i HAVE A 2TIMES BARLOW TO FIT ALSO A SEBEN ZOOM LENSE SO ALL TO TRY OUT AT PRESS i WILL BE UPDATING THE FINAL REULTS IN A FEW DAYS SKY PERMITING i HAVE ORDERED A POWER TANK TO SAVE ON BATTERIES SO NEXT FEW WEEKS WILL TELL THE SKIES HERE ARE FULL OF HEAT HAZE SO MAY HAVE TO WAIT TILL SEPTEMBER AND BE CONTENT WITH OLD MAN MOON OR JUPE IF I AM LUCKY turns out all celestron tackle now made in china including this scope however it is solidly made but I am having great difficulty setting up the go to I put in my location the correct time etc but am having no luck aligning it at this time if I succede i will add more

Very advanced telescope you need large field to point the sky

Being a total newby in amateur astronomy I read extensively through various web sites and product reviews before deciding on the NexStar 4 SE. The three deciding factors at the end were: quality of the instrument, portability and price. So far the telescope has not disappointed me. It is a beautiful instrument, excellent build quality and the computerized star finder is a great tool. If anything I would have liked Celestron to have included an additional eyepiece in the kit as standard. The included 25 mm eyepiece gives a 52 times magnification, which is excellent for viewing the moon, but too low to clearly resolve the planets. Being a 4" device, the magnification can realisticly go up to 240 times, so inlcuding a 12 mm eyepiece or a 2X Barlow lens would have made it a totally perfect experience out of the box.

Cercavo un telescopietto leggero, facile da trasportare e montare, soprattutto preciso nel puntamento automatico: ho trovato tutto quel che cercavo in questo piccolo Nexstar4. Imballo accurato, istruzioni in inglese ma comprensibili, lingua italiana sulla pulsantiera. Facile da montare, basta avere un pò di dimestichezza coi telescopi ed essere astrofili alle prime armi. Per chi è già più esperto poi, nessun problema: operativo in 5-7 minuti. Cercatore a punto rosso: funzionale; va spento dopo l'allineamento col cielo, poiché non ingrandisce nulla ma serve solo a puntare le due o tre stelle scelte per l'allineamento stesso. Poi il telescopio punta in automatico (go-to) quel che si vuole. L'allineamento è anche guidato sulla pulsantiera, step by step, per qualsiasi tipo si scelga di fare (ne sono disponibili più tipi). Unico neo: montatura instabile se c'è vento, dato che il tubo ottico in tal caso vibra. Possibile alimentazione con batteria scooter 12 V, che dà maggior durata rispetto alle pile. Se l'allineamento è fatto bene, il puntamento è preciso, non ha sbagliato un colpo finora e centra tutto nell'oculare (in dotazione ne danno uno da focale 25 mm). Coi suoi 100 mm di diametro, non ha grosse pretese sul deep sky, ma da un cielo decente gli oggetti Messier sono garantiti, con delle difficoltà per alcune galassie. Luna e pianeti ok. Per avere visione raddrizzata (lo strumento non la dà) occorre un prisma raddrizzatore suo, da avvitare al tubo, di difficile reperibilità... io Io l'ho trovato usato su sito inglese.... Per fare foto al fuoco diretto, vuole un suo adattatore da avvitare al fondo del tubo, nella stessa sede del prisma raddrizzatore (bisogna in ogni caso avere T-ring). Anche questo non si trova facilmente. Nel complesso comunque sono soddisfatto e lo ricomprerei.

This was originally bought for a ground based study of satellite antenna and terrestrial microwave physical interference project. I used it to find visible obstructions like buildings, trees, etc following the satellite arc and line-of-site communications at a proposed telecommunications sight. It is quite powerful. For instance, at a 4km distance, it could barely show a single window of a high rise condominium building in is field of view. Since then, it has been used for enjoyment. Looking at the moon, stars, etc. And I have bought many other accessories, lenses, etc for this new hobby. As a star gazer, you might want a more powerful scope, but it has been fun to start with. I bought a camera lens adapter for my digital SLR and have taken some amazing pictures with it. Talk about a telefoto lens! I still struggle with the automatic tracking feature. I guess I need to learn a little bit more about the stars to get it working properly.

Ich habe mir dieses Teleskop gekauft weil, es sehr kompakt und relativ leicht zu bedienen ist. dank der "SkyAlign" Technologie lässt sich das Teleskop sehr leicht ausrichten. Die Einrichtung des Handcomputers ist relativ einfach und gut beschrieben. Das Teleskop kann auch sehr gut als Tischteleskop verwendet werden. Es kann mit 8AA Batterien (nicht im Lieferumfang enthalten) oder, mit einem optional erhältlichem Netzteil betrieben werden. Wenn das Teleskop mit Batterien betrieben wird alten diese ca.4-5 Stunden. Dank dem Leuchtpunktsucher kann jedes Himmelsobjekt sehr leicht anvisiert werden. Fazit : Das Teleskop eignet sich gut als Reiseteleskop und lässt sich leicht handhaben.

Muy bueno , básico pero cumple lo que requeria

This is a good product. But it came with 25mm eye piece and you have to purchase alot of additional stuff to view or gaze. It should have at least two eye pieces like 25 and atleast 9mm with it. And there is no tutorial to teach you how to do it. It may become frustrating for customer company should provide easy installation help one time to customer or easy guide video which shows what a each thing is doing like allignment process is very kinda of seems hard. But it's a overall good product not to mention the seller is amazing I would suggest go for 6se or 8se is best of right budget 127slt is better than 4se
