Qu'est-ce qu'on peut voir avec le Celestron NexStar Evolution C8 ?

La Lune en grand détail et les planètes : les bandes et les lunes de Jupiter, les anneaux de Saturne. Avec 203 mm de diamètre, il capte beaucoup de lumière : sous un ciel bien noir, galaxies et nébuleuses lumineuses deviennent accessibles. Son grossissement utile maximal est d'environ 406× (2 × le diamètre en mm) ; en pratique, la turbulence de l'atmosphère impose souvent de rester en dessous.

Quels oculaires sont fournis et quels grossissements ?

Deux oculaires fournis : 40 mm et 13 mm. Avec 2032 mm de focale, ils donnent 51× et 156×. Pour connaître le grossissement d'un oculaire, divisez la focale du télescope par celle de l'oculaire.

Est-il facile à transporter ?

Il reste transportable en voiture : le tube pèse environ 5,67 kg pour environ 43,2 cm de long et la monture environ 7 kg (plus 5,44 kg pour le trépied).

Faut-il le collimater ?

Rarement. L'optique est réglée en usine ; de temps en temps, un contrôle sur étoile suffit : on pointe une étoile brillante, on la défocalise légèrement et les anneaux doivent être bien concentriques. Si besoin, le réglage se fait avec les vis du miroir secondaire.

Peut-on faire de la photo ?

La monture motorisée suit les objets : c'est idéal pour filmer la Lune et les planètes avec un smartphone ou une petite caméra planétaire, et les planètes apparaissent déjà grandes grâce aux 2032 mm de focale. Les longues poses du ciel profond restent limitées, car une monture azimutale fait tourner le champ.

Que contient la boîte ?

Tube optique, monture à bras unique et trépied, plateau porte-accessoires, WiFi intégré, batterie lithium-fer intégrée, raquette NexStar+, oculaires 40 mm et 13 mm, chercheur point rouge, visual back, renvoi coudé, adaptateur secteur (4 fiches).

L'alimentation est-elle fournie avec le Celestron NextStar Evolution C8 (203mm) SCT Wifi ?

Oui. La monture NexStar Evolution intègre une batterie LiFePO4 rechargeable (9,6 V, 4,5 Ah) et l'adaptateur secteur de recharge est fourni. Aucune alimentation supplémentaire n'est nécessaire.

Frequently asked questions

What can you see with the Celestron NexStar Evolution C8?

The Moon in great detail and the planets: Jupiter’s bands and moons, Saturn’s rings. With a diameter of 203 mm, it captures a great deal of light: under a very dark sky, bright galaxies and nebulae become visible. Its maximum useful magnification is approximately 406× (2 × the diameter in mm); in practice, atmospheric turbulence often limits observation to lower magnifications.

Which eyepieces are included, and what are their magnifications?

Two eyepieces are included: 40 mm and 13 mm. With a focal length of 2032 mm, they provide 51× and 156× magnification. To calculate the magnification of an eyepiece, divide the telescope’s focal length by that of the eyepiece.

Is it easy to carry?

It can still be transported by car: the tube weighs about 5.67 kg and is about 43.2 cm long, and the mount weighs about 7 kg (plus 5.44 kg for the tripod).

Should we aim it at him?

Rarely. The optics are adjusted at the factory; from time to time, a star test is sufficient: point the telescope at a bright star, defocus it slightly, and the rings should be perfectly concentric. If necessary, adjustments can be made using the screws on the secondary mirror.

Can we take pictures?

The motorized mount tracks objects: this is ideal for filming the Moon and the planets with a smartphone or a small planetary camera, and the planets already appear large thanks to the 2032 mm focal length. Long exposures of the deep sky remain limited, since an azimuth mount rotates the field of view.

What's in the box?

Optical tube, single-arm mount and tripod, accessory plate, built-in Wi-Fi, built-in lithium-iron battery, NexStar+ hand controller, 40 mm and 13 mm eyepieces, red-dot finder, visual back, right-angle prism, AC adapter (4 plugs).

Does the Celestron NextStar Evolution C8 (203mm) SCT Wi-Fi come with a power supply?

Yes. The NexStar Evolution mount includes a rechargeable LiFePO4 battery (9.6 V, 4.5 Ah), and the AC power adapter is included. No additional power source is required.
