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

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 faut-il prévoir ?

Aucun oculaire n'est fourni avec cette version. Le grossissement se calcule en divisant la focale du télescope (2032 mm) par celle de l'oculaire : par exemple, un 25 mm donne 81×.

Est-il facile à transporter ?

Oui, c'est un instrument léger : le tube pèse environ 6,35 kg pour environ 43,2 cm de long.

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 ?

Ce tube est vendu seul : les possibilités photo dépendent de la monture choisie. Avec sa longue focale (2032 mm), il est surtout fait pour la vidéo planétaire et lunaire sur une monture motorisée. Le tube pèse environ 6,35 kg : tenez-en compte pour la capacité de charge de la monture.

Product description

Celestron C8 EdgeHD: The Swiss Army Knife of Astronomy

Discover the universe with the Celestron C8 EdgeHD, an aplanatic Schmidt-Cassegrain telescope designed to deliver sharp, aberration-free images, right down to the edges of the widest sensors and eyepieces. Ideal for visual observation and astrophotographic imaging, it combines optical innovation and versatility to meet the needs of amateur and professional astronomers alike.

Superior Optical Quality

Aberration-free images : Corrects coma and field curvature for exceptional sharpness across the entire field of view.
Ultra-flat focal plane: Three times flatter than a conventional Schmidt-Cassegrain, for sharp stars even with the largest CCD or CMOS sensors.
Ideal for modern imaging: Optimizes the capture of every detail.

Optimized mechanical performance

Mirror locking system : Holds the primary mirror in place to reduce movement during long exposures, ensuring a centered image.
Integrated cooling vents : Vents at the rear of the tube for rapid dissipation of hot air, while a 50-micron mesh filter prevents dust ingress.
Fastar compatibility : The telescope can be converted into an ultra-fast f/2 system by removing the secondary mirror and adding a third-party accessory.

Unrivalled optical versatility

Native focal ratio of f/10 : Ideal for capturing the fine details of deep-sky objects.
Adjustable focal length : Focal reducer, Barlow or Fastar options to adapt the field of view to your needs.

StarBright XLT technology

Wide spectrum : Optimizes light transmission on all optical surfaces.
Bright, high-contrast images: Capture more detail in faint objects and complex deep-sky structures.

Individual Test and Quality Guarantee

Every Celestron C8 EdgeHD undergoes rigorous quality control with artificial star and camera tests to ensure optimum performance in the field.

Accessories Included

9×50 Telescope: Easily find celestial objects.
1.25" diagonal mirror: for comfortable observation with eyepieces.
Plössl 40 mm eyepiece: Ideal for beginners.

Versatile applications

Visual observation : Enjoy unrivalled image quality for planets, the Moon and deep-sky objects.
Advanced astrophotography : Capture breathtaking details of nebulae, galaxies and star clusters.
Fast imaging with Fastar : Perfect for maximizing your time under the starry sky.

Conclusion

The Celestron C8 EdgeHD combines optical quality and flexibility to deliver outstanding performance for all your celestial explorations. Dive into the universe with an instrument designed to meet your highest expectations.

Frequently asked questions

What can you see with the Celestron C8 EdgeHD?

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.

What eyepieces should you bring?

No eyepiece is included with this model. The magnification is calculated by dividing the telescope's focal length (2032 mm) by that of the eyepiece: for example, a 25 mm eyepiece provides 81× magnification.

Is it easy to carry?

Yes, it's a lightweight instrument: the tube weighs about 6.35 kg and is about 43.2 cm long.

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?

This tube is sold separately: its photographic capabilities depend on the mount you choose. With its long focal length (2032 mm), it is primarily designed for planetary and lunar video recording on a motorized mount. The tube weighs approximately 6.35 kg: take this into account when considering the mount’s load capacity.
