Is an 8 inch telescope good?
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.
How big of a telescope do you need to see galaxies?
If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to use a telescope with an aperture of 8 inches or more. Bode’s Galaxy (M81) glows brightly enough to show up through binoculars, but the larger the telescope you can point at it, the better.
What is better Newtonian or refractor telescope?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
What can I see with 5 inch telescope?
5-inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 91 arcseconds and can be magnified up to 254 times the human eye. 5″ Optical tubes also make exceptional light gatherers by allowing an observer to see 14.3 magnitude stars!
What can I see with an 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.
How big of a telescope do I need to see the flag on the Moon?
around 200 meters
The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.
