Frequently asked questions

Frequently asked questions

Qu'est-ce qu'on peut voir avec le Celestron NexStar C4 ?

The Moon in great detail, the planets (Jupiter’s bands, Saturn’s rings, Venus’s phases), and double stars: its long focal length naturally provides high magnification. For deep-sky observing, it is limited to the brightest clusters and objects. Its maximum useful magnification is approximately 204× (2 × the diameter in mm); in practice, atmospheric turbulence often requires staying below this limit.

Which eyepieces are included, and what are their magnifications?

Included eyepiece: 25 mm. With a focal length of 1,325 mm, it provides 53× magnification. To calculate the magnification of an eyepiece, divide the telescope's focal length by the eyepiece's focal length.

Is it easy to carry?

It can still be transported by car: the tube weighs about 2.7 kg and is about 34.3 cm long, and the mount weighs about 3.2 kg (plus 4.54 kg for the tripod).

Should we aim it at him?

No, practically never: a Maksutov's optics are factory-adjusted and remain stable, which is one of its major advantages for beginners. To check, a star test is all it takes: point the telescope at a bright star, defocus it slightly, and the rings should be perfectly concentric.

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 1,325 mm focal length. Long exposures of the deep sky remain limited, since an azimuth mount causes the field of view to rotate.

What's in the box?

Optical tube, single-arm mount and tripod, accessory plate, StarPointer red-dot finder, integrated equatorial mount, NexStar+ hand controller, 25 mm eyepiece.

L'alimentation est-elle fournie avec le Kit NextStar C4 ?

Yes. The kit includes a 12-volt Powertank battery, which powers the NexStar SE mount (12 V DC, 750 mA, positive center) both in the field and at home.
