What can you see with a 8 inch telescope?
The Moon, the bright planets, bright binary stars, bright open and globular clusters, bright nebulae, and bright galaxies are all possible targets. Light pollution and nebula filters may be useful to some degree on certain nebulae.
Is an 8 inch telescope good?
For visual observers 8” seems to be a sweet spot for most between image brightness and convenience. Most deep sky objects are just smudges visually in even 10 or 12 inch scope. In most cases good views require a camera and more specialized telescope. Exposure time buys you photons more easily than aperture.
What does an 8 inch telescope mean?
An 8-inch telescope (it doesn’t matter what type) will move you into a new dimension of viewing. The objects you see with an 8-inch scope will reveal more detail. Keep in mind, however, that if you stay interested in observing, you’ll crave even larger scopes.
What is the magnification of an 8 inch telescope?
As you get to 50x or 60x per inch of aperture, some faint extended deep space objects can become too dim to see. Thus, while an 8″ telescope is theoretically capable of a maximum useful deep space power of 480x (60 x 8), that much power is often usable only for splitting close binary stars.
How far can an 8 inch telescope see?
The most distant galaxies that you will be able to see with an 8″ telescope will be about 50 to 100 million light years away e.g. M109 with apparent magnitude 10.3 at distance 83 ± 24 million light years.
What is the focal length of an 8 inch telescope?
Some modern scope designs use a clever optical layout to squeeze a long focal length into a small optical tube. This telescope has an 8″ (200 mm) mirror with an 80″ (2000 mm) focal length, but the light folds into a tube less than 20″ (500 mm) long. More about this type of scope in a later article…
Should I get a 6 inch or 8 inch telescope?
The 6-inch may have a longer focal ratio and may be better at looking at the moon. The six inch is far more portable and user friendly, easier to make a good mirror, and less expensive. The 8- inch would require a heavier mount. Either one would be a good scope.
Is a 10 inch telescope good?
Choosing a 10″ inch aperture scope is a great size where you can find very capable instruments and not needing to spend a fortune. It’s also a great capacity and size factor. These telescopes will not be small or compact yet they have a comfortable size to be able to travel with.
Is a 90x telescope good?
90x magnification should be just fine for Jupiter and Saturn – you’d see the disc of Jupiter clearly with the four Galilean satellites and Saturn’s rings.
