Why do space telescopes produce clearer images than telescopes on Earth?
What Makes Hubble Different From Telescopes on Earth? Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.

How strong 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 do I need to know before buying a telescope?
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.
Is getting a telescope worth it?
Most telescopes that cost less than $300 aren’t really worth it. We suggest getting good binoculars instead. Stay away from any telescope advertised for its magnifying power. For a child, look for a tabletop telescope that’s portable, easy to push around the sky, and virtually indestructible.
How do I know which telescope to buy?
To determine what type of stargazing a telescope is best for, look at its f-ratio. The f-ratio is the telescope’s focal length divided by its aperture. For a telescope with a 900-mm focal length and a 70-mm aperture, this gives an f-ratio of 12.9 or f/12.9.
