The image will be formed at infinite distance as parallel ray come out of the lens after refraction through lens.
When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
If the object is more distant from the lens than the focal length of the lens, a real image is formed.

If an object lies within the focal length of a convex lens, its image will be erect, bigger in size and virtual. It will be on the same side of the object.
The image formed is larger than the object, right-side up, and virtual.

Here's the equation you want. It's called the "Lensmaker's Formula".1/i + 1/o = 1/fi = image distance from the lenso = object distance from the lensf = focal length of the lens
If the object is more distant from the lens than the focal length of the lens, a real image is formed.
A concave lens will appear!

1/(focal length) = 1/(distance of object) + 1/(distance of image) is the formula for calculating x of a lens knowing only the focal length which is the distance from the lens to the image of sun formed by it.
The telescope has an object lens at the top, which is a large lens with a long focal length. It produces an inverted image of a distant obect at the focal point. The eyepiece is a smaller lens, and you look through the eyepice at the image formed by the object lens. The image is formed in space, it does not need a screen, and you can see it with the eyepiece. The ratio of the focal lengths of the two lenses is the linear magnification.
If an object lies within the focal length of a convex lens, its image will be erect, bigger in size and virtual. It will be on the same side of the object.
Convex (I prefer converging lenses) lenses are thicker in the middle than at the edges. This causes the rays to converge towards the principle axis (line running through the center of the lens perpendicular to the surface). two images will be formed. When the object you are viewing is farther from the lens than the focal length you will have an inverted real image. This image can be enlarged (when the object is between the focal length and twice the focal length), the same size (when the object is twice the focal length from the lens) or reduced (when the object is beyond twice the focal length). When the object is closer to the lens than the focal length you are using the lense as a magnifying glass and you will have an upright virtual image.
The image formed is larger than the object, right-side up, and virtual.
The image is formed behind the lens at a distance equal to the focal length. If the distance to the object is D1 and the focal length is F, then the distance D2 to the image is given by this equation: 1/D2 = 1/F - 1/D1
