Answer

Brief Explanations:

  1. Reflecting telescopes don't suffer from chromatic aberration (rainbow - like halo) as they use mirrors instead of lenses for the primary optical element.
  2. They can be made large as mirrors can be fabricated in large sizes more easily compared to lenses.
  3. Only the reflecting side of the primary mirror needs to be precisely shaped and smooth, reducing manufacturing complexity. The statement about using only lenses is incorrect as they use mirrors. The eyepiece creating an image is a feature of all telescopes and not a unique advantage of reflecting ones.

Answer:

There is no rainbow - like halo around the image. Reflecting telescopes can be made very large. Only the reflecting side of the primary mirror needs to be perfectly shaped and smooth.
