Can a telescope have 3 lenses?
Yes. Apochromatic refractors often use 3 lenses in order to focus all visible wavelengths of light at a single point to minimize or eliminate chromatic aberration.
Why do most professional telescopes select reflectors over refractors as their primary optical design?
Professional telescopes often select reflectors over refractors as their primary optical design because reflectors are generally more cost-effective and can be made with larger apertures, allowing for better light-gathering capabilities and higher resolution images. Additionally, reflectors are less prone to chromatic aberration, which can distort images in refracting telescopes.
Which type of telescope was invented first?
The telescopes used by Leeuwenhoek, Huygens, and Galileo were refractors. Newton fashioned the first reflector, with a primary mirror of made polished brass.
Where do reflecting telescopes work best?
All telescopes work best in the vacuum of space. Aside from that, "where" really is not a great factor compared to other types of telescopes. The distinct advantage of some reflecting telescopes is that they don't suffer from chromatic aberration like refractors do.

Why are most large telescopes reflectors instead of refractors?
Most large telescopes are reflectors instead of refractors because reflectors are better at gathering and focusing light, allowing for clearer and more detailed images of distant objects in space. Reflectors also do not suffer from chromatic aberration, a common issue with refractors that can distort images.
