During 1976-1986 years spectral investigations of X-ray binary A0535+26 = HDE 245770 and runaway supergiant HD 188209 were carried out with the 6-m telescope. The probable orbit of Be-star HDE 245770 with P=35d1 is suggested, P« Harmanec has also found a period of 0d187 in radial velocities. At times of 1h Hp emission profiles are variable, A search for pulsar period (P=104 a) in positional and photometric parameters of emission has given no positive results, profiles of the runaway HL 188209 varies from night to night. The orbit with P= 18d84 is found together with probable nonradial pulsations at times of -^1 day.
