Alpha Centauri is the name given to what appears as a single star to the naked eye and the brightest star in the southern constellation of Centaurus. At 0.27 apparent visual magnitude (calculated from A and B magnitudes), it is fainter only than Sirius and Canopus. The next-brightest star in the night sky is Arcturus. Alpha Centauri is a multiple-star system, with its two main stars being Alpha Centauri A ( Cen A) and Alpha Centauri B ( Cen B), usually defined to identify them as the different components of the binary Cen AB. A third companion--Proxima Centauri (or Proxima or Cen C)--is much further away than the distance between stars A and B, but is still gravitationally associated with the AB system. As viewed from Earth, it is located at an angular separation of 2.2 from the two main stars. Proxima Centauri would appear to the naked eye as a separate star from Cen AB if it were bright enough to be seen without a telescope. Alpha Centauri AB and Proxima Centauri form a visual double star. Together, the three components make a triple star system, referred to by double-star observers as the triple star (or multiple star), Cen AB-C.

Can we conclude that can you see alpha centauri without a telescope?
yes
