Picture of Jupiter's moons without a telescope

In summary, the conversation is about someone taking a picture of Jupiter's moons without a telescope using a 300 mm zoom lens on a Canon Digital Rebel. They mention using a tripod and a Tameron 70-300 lens in manual mode with a 2 second exposure. They also plan to try using the stock lens in the future when Jupiter returns to the evening sky.

COOL! How did you manage that?
Tripod shot. Tameron 70-300 lens on a Canon Digital Rebel. Manual mode, 2 second exposure. I forget the ISO. Probably the stock lens (?-70 mm) will get a photo of the moons too. I have to wait till Jupiter returns to the evening sky.

The four largest moons of Jupiter that can be seen without a telescope are Io, Europa, Ganymede, and Callisto. These are also known as the Galilean moons, named after the astronomer Galileo Galilei who discovered them in 1610.

2. How far away can Jupiter's moons be seen without a telescope?

The distance at which Jupiter's moons can be seen without a telescope varies depending on the brightness of the moon and the clarity of the sky. On a clear night, these moons can be seen from approximately 400 million miles away.

3. Why are these moons visible without a telescope?

These moons are visible without a telescope because they are relatively large and bright, with diameters ranging from 2,000 to 4,000 miles. They also reflect light from the sun, making them easier to see in the night sky.

4. Is it possible to see Jupiter's moons without a telescope from anywhere on Earth?

Yes, it is possible to see Jupiter's moons without a telescope from anywhere on Earth, as long as the sky is clear and the moons are in the right position. However, they may be more difficult to see in areas with light pollution.

5. Can the colors of Jupiter's moons be seen without a telescope?

No, the colors of Jupiter's moons cannot be seen without a telescope. These moons appear as small white dots in the night sky, and their colors can only be seen through a telescope or captured in images taken by spacecraft.
