A bigger one.
Several factors contribute to the power of a telescope. The size of the objective or primary mirror is a crucial factor, as a larger diameter allows the telescope to capture more light. The quality of the optics and the level of precision in their construction also affect the power of a telescope. Additionally, the type and quality of the eyepiece used can further enhance the power by magnifying the image.
The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.
The most powerful telescope is the Hubble telescope, please note you did not ask where.
The difference between the 10mm and 20mm lenses is the focal length they provide. The 10mm lens will give you higher magnification and a narrower field of view, while the 20mm lens will give you lower magnification and a wider field of view. Choose the lens based on your observing preferences and the object you want to view.
It refracts (bends) light into a focal point

-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.
A telescope lens works to magnify distant objects by bending and focusing light rays that enter the lens. This allows the lens to gather more light and bring the image of the distant object into focus, making it appear larger and clearer when viewed through the telescope.
The light-gathering power of a telescope is determined by its aperture, which refers to the width of a telescopes primary mirror or objective lens.
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.

It's much more powerful

The focal length of EyePiece is relatively larger to that of the Objective lens. Power of a lens is inversely proportional to it's focal length. Therefore, Objective is slightly more powerful than EyePiece.
The "objective" lens (as opposed to the eyepiece).
