What does f10 mean on a telescope? Wide field telescopes have a focal ratio of f/7 or less. Focal ratio also influences the brightness of extended objects like a nebula or galaxy. For example, a telescope with focal ratio of f/5 will show an image of four times the brightness as a telescope with focal ratio of f/10, all other things being equal.
Then, What can I see with a 40x telescope?
At 40x you can use the scope for several astro viewing aspects: Clusters, Open and Globular, double stars, some nebula – M42 being the obvious. Depending on how dark your skies are some planetary nebula. And as ever in this hobby there is the moon.

What telescope can see the farthest?
The furthest galaxy ever observed by the Hubble telescope is the GN-z11 galaxy, about 13.4 billion light-years away. As the galaxy is so far away and light can only travel so fast (299,792,458 meters a second), Hubble is effectively looking back in time when viewing very distant objects.
Can I see Saturn with a 60mm telescope?
Jupiter and Saturn are two of the finest showpieces in the sky for the 60mm scope. Typically about a dozen asteroids will be bright enough on any given year to be seen with a 60mm telescope. Also, usually two or three comets appear that can be seen, sometimes more.
Is 60 mm telescope good?
