【国内正規品】 CELESTRON 天体望遠鏡 ネクスター 8SE [CE11069] 147409

初心者の私としては手に余る高性能でした。 シュミットカセグレンは正確に光軸調整しなければ酷いピンボケ、 温度管理も厳密にしなければ像はムラムラ。 焦点距離の長さが仇となり空気の悪さが極端に画像劣化につながります。 ネットで調べながら調整を進めている途中ですが、条件が揃えば素晴らしい性能を発揮します。 スカイアライメント等の性能も申し分ありません。 ただ、国内販売店から買う気はしないですね。 私は$999＋送料$300＋国内送料3,000円で米国から直接 通販で購入しました。 アイピース等のオプションも全て日本の半額で買えます。 故障時の修理は自己責任となりますが、差額でもう１台買えますからね。

米アマゾンでの価格は1079ドルの商品です。 国内正規品は、日本語マニュアル、日本国内での保証、日本語化ハンドコントローラーが付いて 22万8千円になります。（2013年6月13日現在） 国内正規代理店であるサイトロンジャパンの名前が明記してあるにも関わらず、並行輸入品を販売 する業者さんは倫理観が欠如しているとしか思えません。一部業者さんは国内正規品より高い価格 で登録している始末です。 amazonにはメールを送りましたが対処がなされていないようなのでここで注意喚起させて頂きます。 ※追記 星一つの評価をさせていただいていましたが、商品自体の評価とは無関係でありレビュー本来の趣旨 とは違ってしまいますので、改めて星三つにさせていただきました。

This is my second scope. The first was a Bushnell 4.5 inch reflector of disputable quality. The mirror was good, but I had to replace the flimzy tripod and get better eyepieces to even attempt to see anything clearly. This telescope is superior a hundred fold . The image of jupiter, for instance, is crisp and clear with the included 25mm eyepiece, Seeing hasn't been very good here, in Quebec City, these last few days, but I was able to observe the king of planets with a 10mm eyepiece and enjoy details impossible to discern with my old reflector. Allignement of the go to is relatively simple. The hand controller has a red backlight to preserve night vision. However, with the backlight on during allignement, the scrolling of instructions on the hand controller display is unreadable. Tracking is good, but I have noticed that occasionaly, the scope seems to loose track of the object, which makes it necessary to use the hand controller to bring things back on track. One of the reasons I purchased this scope was because it can be easily transported and assembled. The tube need not be removed from the mount. It can be rotated vertically to align with the mount arm into a neat compact package easily storable in my OTA bag. The tripod is also compact and light. Contrary to other comments, I find the tripod and mount well built and sturdy enough for the nexstar. A question of opinion, I suppose. I purchased the 18774 power tank with this scope, which I think is essential. The tracking motor will eat through the required AA batteries in no time. I also burchased the AC adapter. There is only one 25mm eyepiece included with the scope. The purchase of a few more of different magnification, a barlow and a few filters such as a lunar filter is a good idea. However, the nexstar is highly usable with the included accessory. There are many resources on the web which are helpful in the use of this SCT. Michael Swanson's Nexstar site, for one, has a lot of good info, although some of it seems outdated. Youtube is also a good source of valuable information. Included in the box: Scope and tripod (obviously) , tripod accessory tray, level for the tripod, 25mm eyepiece, 1.25 inch Star diagonal, Starpointer finderscope, The Sky Level 1 Astronomy Software, NexRemote telescope control software, RS232 Cable (you'll need an RS232 to USB adapter for newer computers) The good: Crisp image Easy assembly Easily transportable and storable Sturdy enough tripod Easy alignement with the hand controller The Bad: Scrolling text on the hand controller is unreadable when backlight is on. Tracking sometimes lost. To conclude, I have so far no regrets with my purchase. And although I have only a few hours of observations with the scope, I am quite satisfied. With mars and saturn soon to be in opposition, I believe the next few weeks will bring loads of astronomical fun. ***After a couple months of use, I thought it would be a good idea to share my experience with this scope. I had mentionned in my initial review that the scrolling text on the hand controller (HC) was unreadable at night, with the red backlight on. As I navigated through the numerous menus on the HC, I realized that I could set the speed of the scrolling, which pretty well solved that problem. So scratch that from the "Bad". The gears in this scope produce some backlash. This problem is well documented on the web and must be taken into consideration when attempting to do a proper star alignement and expect the scope to center on planets. Without some ajustements in the settings of the HC, planets will never align properly in your eye piece once the star alignement has been performed. I've found some very helpful astronomy forums with valuable info regarding different settings to minimize the impact of this backlash. I've added a spotting scope which makes the optical tube back heavy. I had no idea that this could have an impact on the the alignement, but it does. Call that a newb's mistake, I suppose . All in all, my experience with this telescopes has greatly improved with the knowledge collected on the web. So, the second point on my "bad" list still applies, but it can be remedied. My allignements are still not perfect. I still have to test some settings, but I'm getting very close. It's only a matter of time. But all this does not minimize the fact that this great telescope has enabled me to observe the marvels of our solar system and beyond with a clarity that truly amazes me. It's easy to set up, light and transportable. A great buy for a beginner like myself, and certainly for more experienced amateur astronomers. And worthy of its fifth star. (PS. The celestron GPS for this scope is a very helpful addition, by the way.) Celestron 93969 SkySync GPS Accessory

Il prodotto è di buona fattura, non ho trovato difetti di sorta. Buono anche l'imballaggio che può essere usato anche per lo stoccaggio dello strumento. Il treppiede è ben fatto e solido ed è di rapido montaggio con la testa della montatura. Per i principianti come me, consiglio di scaricare il software Celestron per aiutare l'allineamento del telescopio e per l'update del computer della montatura. Sono molto soddisfatto dell' acquisto.

This is my first telescope since I was a teen. Setting up the telescope wasn’t easy. Need patience, but once set up great views. As the telescope only comes with one lens, you should include additional lenses with greater magnification.

Mer teleskåp än jag väntat mig Att prövas när det är möjligt för alla molnen.

Possesseurs de plusieurs équipements optiques (longue,vue, jumelles...) je voulais acquérir un télescope facile d'utilisation et me permettant d'observer prioritairement notre système solaire (Jupiter et ses lunes, Saturne et ses fabuleux anneaux). Ce modèle NexStar 8SE de Celestron m'attire depuis un certain temps car il m'a paru présenter un bon compromis en terme de rapport performance/prix tout en étant accessible à mon budget. Doté d'une technologie moderne il offre une vision directe en temps réel de l'image sans passer par un traitement numérique long (et fastidieux) préalable comme c'est fait dans les télescopes numériques récents (et onéreux) qualifiés "intelligents". Ce modèle est intéressant avec son miroir 8 pouces et moderne car conçus pour être piloté par informatique (intégrée) et le cas échéant par le PC. Ce télescope arrive en trois pièces principales plus quelques accessoires (pertinents) dans un packaging absolument impeccable et livré avec soin par Chronopost. Je ne l'ai pas encore utilisé car il réclame un travail de calibration et de paramétrage et la période de décembre n'est pas idéale pour réaliser ce travail de paramétrage. Je donne néanmoins 5 étoiles pour le packaging impeccable et l'excellente qualité de fabrication et des composants intégrés. Ce télescope est très bien évalué par les utilisateurs sur Internet. J'espère que la mise en route va se passer sans difficulté. Je compte compléter mon commentaire dans quelque temps après l'avoir monté et essayé. Entre-temps, je prévois de l'enrichir par un supplément d'accessoire. Je suis très content de mon achat.
