An estimate of the maximum observable redshift is obtained using only t_{ 0} approximately equal to (14+- 3)10^{ 9}years, H_{ 0} approximately equal to 65 +- 10Km\sec^{ -1}Mpc^{ -1}(t_{ 0}H_{ 0} approximately equal to 0.91 +- 0.08/0.18) assuming \Lambda approximately equal to 0. The resulting maximum redshift z_{ +} approximately equal to 10 appears to give a reasonable upper limit to the highest actually observed redshifts. Some implications are discussed.
