I think you misspoke slightly. You would never actually be able to see the BB itself. For some undetermined amount of time after the BB the entire universe was opaque. It was a sea of individual atoms that were still superheated but did not emit light in the former of photons.
This is true, for several (hundred?) million years after the Big Bang the universe was opaque.
Horizon documentary on the first stars that formed called Cosmic Dawn. Very well made like all of bbc's stuff

Well, it can't have been more than 400 million years because the Hubble Telescope has recorded a well-formed galaxy at that time. Galaxy GN-z11 is young and full of new stars at that time but it probably too many millions of years for it to form.
