Characters who have displayed telescopic visionEdit
Clark Kent - This ability first manifested in Slumber although he would often look at the stars in space by combining his enhanced eyesight with the aid of his telescope when he was younger. Clark can, according to himself, see 50 feet in all directions and angles. (Pilot)
Kara Kent - Kara used this ability to see earthly objects from outer-space. (Veritas)
Isis - Isis, while occupying a host, has the ability to see objects and people from afar. (Isis)
When Clark was younger, he wasn't able to see things at the intensity that he can now, so he used a telescope to aid him combine with his already heightened vision.
