Qu'est-ce qu'on peut voir avec le Celestron StarSense Explorer 127 ?

The Moon in detail, the planets (Jupiter’s bands and moons, Saturn’s rings), and, under a dark sky, the brightest clusters and nebulae, such as the Orion Nebula. Its maximum useful magnification is approximately 254× (2 × the diameter in mm); in practice, atmospheric turbulence often makes it necessary to stay below this limit.

Which eyepieces are included, and what are their magnifications?

Two eyepieces are included: 25 mm and 10 mm. With a focal length of 1,000 mm, they provide 40× and 100× magnification. To determine the magnification of an eyepiece, divide the telescope's focal length by that of the eyepiece.

Is it easy to carry?

The tube weighs about 3.44 kg and is about 45.7 cm long, and the tripod weighs about 1.7 kg.

Should we aim it at him?

Yes, just like any Newtonian telescope. A quick check every now and then is enough, especially after transporting it. With a collimation laser, it’s quick and easy. At f/7.9, it’s fairly forgiving: a slight misalignment is hardly noticeable.

Can we take pictures?

The included smartphone adapter lets you take souvenir photos of the Moon and the planets—but that's all. Deep-sky photography isn't possible: the mount doesn't track the sky's movement.

What's in the box?

Optical tube, mount, and tripod (pre-assembled), 25 mm and 10 mm eyepieces, 2× Barlow lens, StarPointer red-dot finder, accessory plate, StarSense Explorer smartphone mount.
