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.
Can you see Andromeda with 8-inch telescope?
Located south of Andromeda, this fainter galaxy will be hard to spot even in an 8-inch telescope if the night isn't perfectly dark. The Andromeda Galaxy, the Triangulum Galaxy and our own Milky Way are the three largest members of our local cluster of galaxies, imaginatively called 'The Local Group'.Dec 7, 2021
What can you see with a 8 Dobsonian?
You will be able to see quite a bit! Open clusters and globular clusters will be great, although the fainter globs won't look like much. Some galaxies won't be visible due to your moderate light pollution but many will.
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…Apr 4, 2020
What is a good size telescope?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. For most purposes, a telescope's maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you'd need a 12-inch-wide scope to get a decent image at 600×.
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.
What can you see with a 8-inch reflector?
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 Dobsonian telescope worth it?
It is bigger and heavier but still manageable in 2 trips. I really like having the extra aperture under dark skies and think it's worth the extra effort to see more. At home I prefer the 8" with the lighter weight and quick easy setup.
What is the most popular size refractor telescope?
- Sky-Watcher 120mm Refractor Telescope Best Overall. Check Price on Optics Planet.
- Orion ED80T Refracting Telescope. Check Price on Optics Planet.
- Gskyer Refractor Telescope Best Value.
- Celestron AstroMaster Refracting Telescope.
- Meade Infinity 102mm Refractor Telescopes.
What size of the telescope is best to use?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than a smaller one can.
Which is better 60mm or 70mm telescope?
However, a 70 mm refractor (which collects 36% more light than a 60mm telescope) is considered by many amateur astronomers to be the minimum size for a good quality beginner refractor telescope. It is acceptable for observing bright objects like lunar details, planets, star clusters, and bright double stars.
What can I see with a 80mm refractor telescope?
The 80mm objective lens and short 400mm (f/5.0) focal length are perfect for taking in wide swaths of the heavens, making it ideal for larger deep-sky objects. You'll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system.
