What is a good power for a telescope? - Promautengineeringsolutions

As a rule of thumb, the maximum usable power is equal to 50-60 times the aperture of the telescope (in inches) under ideal conditions. Powers higher than this usually give you a dim, lower-contrast image. For example, the maximum power range on a 90mm telescope (3.6 in aperture) is 180x-216x.13 Nov 2014

What is a good magnification on a telescope?

50x per inch Experienced planetary observers use 20x to 30x per inch of aperture to see the most planetary detail. Double-star observers go higher, up to 50x per inch (which corresponds to a ½-mm exit pupil). Beyond this, telescope magnification power and eye limitations degrade the view.

Is 400mm good for a telescope?

With 400mm you could watch objects like: Andromeda galaxy core. Orion nebula, other large emission or reflective nebulae (e.g. Pleiades) large star clusters.

Is a 114mm telescope good?

114mm aperture has impressive light-gathering capability to provide excellent views of planets and bright deep sky objects. Fast focal ratio (f/5.2) shortens exposure times for deep sky photography . Pan and tilt control on alt-azimuth mount allows for smooth movements when navigating the night sky.

Is a 70mm telescope good?

With a 70mm telescope, you will easily be able to see every planet in the Solar System. You will also be able to take a great look at the Moon and clearly distinguish most of its recognizable features and craters. Mars will look great. … The magnitude limit of a 70mm telescope is about 11.9.

What can you see with a 100mm telescope?

How powerful does a telescope have to be to see the rings of Saturn?

25x The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.

What can you see with a 130mm telescope?

With a 130mm (5. 1") aperture size, the Polaris 130 will deliver bright, clear images for the aspiring astronomer to enjoy. Whether you're viewing the Moon, planets, or deep-sky objects such as nebulae, galaxies, and star clusters, the view through the Polaris 130 will keep you looking up for a long time.

How far can a 400mm telescope reach?

On a full-frame camera, with a 400mm lens, you can reach up to 8x zoom and on a crop-sensor having 1.5 crop factor, you can get results of up to 600mm lens with the same 400mm lens. If you mean how far it can shoot, then you can shoot as far as you need.
