TELESCOPE FOR VIEWING THE PLANETS

The Planets of our Solar System (Mercury / Venus / Mars / Jupiter / Saturn / Uranus / Neptune) are characterized by :

► Their small size
► Their relative brightness

Your equipment must have the following features

1. TELESCOPE

► High magnification
This is the most important criterion for the observation of planets because they have small apparent sizes.

► Average diameter
As the planets are brighter than deep sky objects, they require a smaller aperture to be visible. Indeed, it is often advisable to value magnification over diameter, but the latter must be sufficient to show maximum detail and provide optimum quality.

► Small focal ratio
As we value the focal length over the diameter of the tube, the focal ratio of a telescope intended for planets is often high.

2. EYEPIECE

► Small focal length
To increase the magnification (Magnification = Tube focal length / Eyepiece focal length)

3. MOUNT

► Manual or motorized tracking
If you want to photograph the planets, an azimuthal mount is sufficient because the exposures are very short. In visual observation, automatic tracking (motorized equatorial mount or azimuthal with Go-To) saves you from having to manually re-orient the telescope when the celestial body leaves the field of view.

4. FILTER

► Color filters
The color filters serve to highlight the details of the surface of each planet.
